ROM Address	Length	Type	Description	Details
$008000	39 bytes	ASM	This is the starting address of SMW. This takes care of basic initialization such as disabling IRQ, HDMA, DMA, clearing the SPC ports, enabling F-blank, disabling emulation mode, disabling decimal mode, initializing the direct page, and setting up the stack.
$008027	43 bytes	ASM	This is code is responsible for uploading the OAM clear routine to $7F8000. The uploaded routine is essentially an unrolled loop which stores #$F0 to all of the OAM mirror($0200) Y positions.
$008052	25 bytes	ASM	This is the main part of the SMW initialization routine. SPC engine upload, sample upload, OAM setup, windowing setup, and RAM clearing all happens here.
$00806B	14 bytes	ASM	This is the main game loop of SMW. It is used to wait for V-blank to complete before executing the code of the next frame. One of the frame counters ($13) is also incremented here.
$00810E	15 bytes	Subroutine (JSR)	OW Music uploader.
$008134	37 bytes	Subroutine (JSR)	Uploads level music bank.
$008159	17 bytes	Subroutine (JSR)	Credit music uploader.
$00816A	522 bytes	Misc.	SMW's NMI routine. For more information, see here.
$008179	49 bytes	ASM	Handles transfers to and from the SPC700 (I/O). Changing all values to [EA] (NOP) or jumping over the code effectively mutes all sound.
$008293	1 byte	Misc.	How many scanlines the status bar uses during a regular level.
$00835D	1 byte	Layer 3	How many scanlines the status bar uses during the battles with Bowser, Ludwig, and Reznor.
$008370	1 byte	Layer 3	How many scanlines the status bar and ceiling use during the battles with Morton and Roy.
$008374	162 bytes	Misc.	SMW's IRQ routine.
$008449	44 bytes	Misc.	Code that transfer Sprite OAM mirror (sprite OAM table at $7E0200-$7E041F, a total of 544 bytes) to register $2104 to draw sprites.
$008494	52 bytes	Sprite tilemap related	Copies OAM's extra bits (size and 9th bit X position: `%000000SX`) data stored in $7E0420, and reformats, or “compacts” each 4 bytes of that into each byte to $7E0400 (`%SXSXSXSX`).	$0420 and $0400 format
$0084C8	8 bytes	Subroutine (JSL)	JSL wrapper for the stripe image uploader (pointer lies in $12), which can be found at $0085D2. Because it upload tiles, it must run in either f- or v-blank (e.g. in NMI).
$0084D0	258 bytes	Stripe Image	Stripe image pointer table. Each 24-bit pointer here corresponds to a value of $12, but only multiples of 3 are used (the first pointer is for value $00, the second is for value $03, the third for $06, etc.).
$0085D2	40 bytes	Subroutine (JSR)	Subroutine which uploads the stripe image pointed by $12 to VRAM. The pointer is loaded from the table at $0084D0, and then the routine at $00871E is called. Afterwards, if $12 is #$00, the stripe image length at $7F837B is set to 0 and the terminator $FF is written to the beginning of $7F837D. In any case, $12 is reset to 0 before returning. To call this routine from outside bank 0 you can JSL to the wrapper at $0084C8. This should only be done during a blank period (usually NMI).
$0085FA	86 bytes	Subroutine (JSR)	Fills the entire layer 3 tilemap with tile 0x0FC (transparent tile) i.e. the code "empties" it. Also wipes the OAM before returning.
$008650	119 bytes	Subroutine (JSR)	This is the routine that polls the controller and updates $15, $16, $17, $18. $0086A0 (x8A0) - Change to [9C A0 0D AD A0 0D A2 00] to cause both player 1 & 2 to be controlled by controller 1.
$0086C7	24 bytes	Subroutine (JSR)	Subroutine that initializes the OAM table in Roy, Morton and Ludwig's rooms. It first initializes the first 100 tiles to be 16x16 (by setting $0420,x to #$02), then jumps in the middle of the standard OAM clear routine (JSL $7F812E).
$0086DF	27 bytes	Subroutine (JSL)	Pointer subroutine: Jump to a 2-byte pointer, the position of the pointer used is "Position after the JSL + 1 + (A*2)". The subroutine should always be accessed by a JSL.
$0086FA	36 bytes	Subroutine (JSL)	Pointer subroutine: Jump to a 3-byte pointer, the position of the pointer used is "Position after the JSL + 1 + (A*3)". The subroutine should always be accessed by a JSL.
$00871E	143 bytes	Stripe Image	Stripe Image Uploader. Uses $00-$02 as a 24-bit pointer to tile data. See this thread how the stripe image format works. Must be run during a blank, usually NMI. To call from a custom routine, do this: - Store stripe image pointer (24-bit) to $00-$02 - Push 24-bit return address (bank -> mid -> lo) - PHB : LDA #$00 : PHA : PLB - PEA $84CD - JSL $00871E
$0087AD	617 bytes	Subroutine (JSL)	This routine is the DMA routine in charge of updating layers one and two as needed. This is controlled by the addresses $1BE4 and $1CE6 when they are a non-zero value.
$008A4E	43 bytes	Subroutine (JSR)	Clear RAM subroutine. This is part of the reset routine. Specifically, it clears ram $00-$FF (direct page), $0200-$1FFF, $0681 and the stripe image table (by setting $7F837B to #$0000 and the start of $7F837D to #$FF).
$008A79	59 bytes	ASM	The routine that sets up certain VRAM-related registers in normal levels. - $008A80: Default value for $2107 [23]. - $008A85: Default value for $2108 [33]. - $008A8A: Default value for $2109 [53]. - $008A8F: Default value for $210B [00]. - $008A94: Default value for $210C [04]. - $008AAB: Default value for $2130 [02], although it's actually stored to the mirror here (i.e. $44). $210A is never set, since it is only ever used in Mode 0.
$008ACD	138 bytes	Subroutine (JSR)	Routine that updates the mode 7 matrix parameters mirrors at $2E-$34 using the rotation and scale parameters at $36-$38. SMW calls it every frame in mode 7 bosses (when $0D9B is >= #$80), and the "Easy Mode 7 patch" calls it every frame in mode 7 levels, but you may need to call it manually if you're using mode 7 in special situations (for example, on the Overworld). On SA-1 roms, this must be called when running on the SNES CPU.	Call routine code
$008C59	40 bytes	Layer 3	Tile array for numbers in bonus star counter.
$008C81	126 bytes	Layer 3	Default status bar tiles info table. Format for each 8x8 tile: %TTTTTTTT %YXPCCCTT $008C81-$008C88: top line of status bar (4 top tiles of the item box) $008C89-$008CC0: Second line of status bar $008CC1-$008CF6: Third line of status bar $008CF7-$008CFE: bottom line of status bar (4 bottom tiles of item box)	Table of addresses
$008D8B	1 byte	Timer	Timer speed (USE WITH $008E2E)
$008D90	28 bytes	Misc.	These four tables indicate the DMA settings and the source address to use for the status bar tiles (the ones that are uploaded at the very beginning of the level). The tables get stored in the order of $43x0-$43x6.
$008DAC	59 bytes	Layer 3	The routine that draws the status bar onto the screen. It uses DMA to write the Layer 3 tiles to VRAM.
$008DF5	5 bytes	Layer 3	The tiles that make up Luigi's name in the status bar.
$008DFA	4 bytes	Sprite tilemap related	Tilemap of reserve item. First byte is mushroom, second is flower, third is star, fourth is feather.
$008DFE	4 bytes	Sprite tilemap related	YXPPCCCT of stars in the item box. It cycles between the four entries every second frame.
$008E02	4 bytes	Sprite tilemap related	YXPPCCCT data for reserve item. First byte is mushroom, second is flower, third is bypassed ($008DFF), fourth is feather.
$008E06	20 bytes	Layer 3	Bonus star counter tilemap - 2 bytes for each number. Every first byte is for the upper tile, every second byte for the bottom tile.
$008E1A	480 bytes	Layer 3	The routine that updates the values of all the addresses used for the status bar ($0EF9-$0F2F). $008E28 - Change this address to AD to disable the timer. $008E2E - Timer speed (USE WITH $008D8B) $008E45 - Tile that each timer digit resets to after reaching 0. Can be any value from $00-$80. (e.g. Change to $0F: 100 -> 0FF -> 0FE ... 0F0 -> 0EF ... etc.) $008E5C - Time is Running Out SFX. Change from FF to 00 to stop the music from speeding up when time reaches 99. $008E6B - [22 06 F6 00] Change to [EA EA EA EA] to not kill Mario when the timer reaches zero. The timer will count down normally and stop at zero, but Mario will not die $008EDB - Change this and/or $008F09 from 20 12 90 to EA EA EA to disable writing the score to the status bar when playing as Mario and/or Luigi, respectively. Useful if you want to place another counter in place of the score using Smallhacker's Status Bar Editor. Note: This alone will NOT stop writing blank tiles if the first N tiles/bytes at $0F29-$0F2E contains the value #$00 (the "0" graphic). To prevent that, consider using this patch. $008EE3 - Change to BRA [80] to write zeroes instead of blank tiles to Mario's score counter. Use with $008F11. $008F11 - Change to BRA [80] to write zeroes instead of blank tiles to Luigi's score counter. Use with $008EE3. $008F2C - How many coins you need to get an 1up (USE WITH $008F37) $008F2F - [EE E4 18] Change to [EA EA EA] to not gain a life after collecting enough for one. $008F37 - Number of coins to subtract from the counter when you gain enough for a 1up (Default: $64 (100). Change to [01] to create a coin wallet effect - use with $008F2F. $008F41 - (Use with $008F45) Maximum life limit, minus one. Warning: Changing this to anything higher than 0x7E (127 lives) will remove the life limit entirely! Also, if you have more than 99 lives, the life counter will appear slightly glitched. $008F45 - (Use with $008F41) Maximum life limit, minus one. Note that if you have more than 99 lives, the life counter will appear slightly glitched. $008F62 - Number of bonus stars required to enter bonus game $008F67 - [8D 25 14] Change to EA EA EA to disable entering bonus game when player has 100 bonus stars. $008F6F - Amount of bonus stars that will be subtracted when 100 bonus stars are collected. Change to [01] to make 99 the maximum amount of bonus stars you can get - to create a bonus star wallet effect, use with $008F67. $008F7E - Writes coins to status bar. Changing to [EA EA EA EA EA EA] will disable the coins from being written to the status bar. $008F95 - [09] The X position of the small bonus star counter in the status bar. $008FC5 - [20 79 90] Change to EA EA EA to disable the item GFX in the status bar $008FCE - Length of "LUIGI" text (Status bar) $008FE7 - [FC](blank tile) Tile used on the status bar when there's no Yoshi coin in that spot. $008FED - [2E](coin tile) Tile used on the status bar when there is a Yoshi coin in that spot. Change to [FC](blank tile) to visually disable collected Yoshi Coins.
$008F1D	30 bytes	Misc.	Routine that handles actually increasing the player's coin count and giving a life from 100 coins, controlled by RAM address $7E13CC.
$008FDC	1 byte	Layer 3	[05] If the player has collected at least this number of Dragon Coins, the status bar will display $008FE0 Dragon Coins instead (none by default).
$008FE0	1 byte	Layer 3	[00] Number of Dragon Coins to display in the status bar, if the player has collected at least 5.
$008FF0	2 bytes	Layer 3	Location of the first Dragon Coin tile in the status bar.	Diagram
$008FFA	24 bytes	Misc.	Table containing six 32-bit numbers representing hexadecimal powers of 10, used by the 6-digit HexToDec routine at $009012 used to display the player's score. The numbers are not direct 32-bit values, though, and are instead two consecutive 16-bit values that are directly concatenated together. For instance, the number 100000 (0x186A0 is hex) is represented here as [$0001,$86A0].	16-bit values
$009012	51 bytes	Subroutine (JSR)	6-digit HexToDec subroutine, used to write a player's score into status bar (note: although the score is shown in-game as 7 digits, the 7th digit is just a static 0 tile). This function calculates the digits by repeatedly subtracting powers of 10 (in hexadecimal) from the input number until no more can be subtracted. Input: - Y: Set to #$00 - X: Status bar position to write to (indexed from $0F15) - $00-$03: Hexadecimal value to convert. Note that this is not provided as a normal 32-bit value, though, and instead should be provided as two 16-bit values, with $00 being the high word and $02 being the low word.
$009045	12 bytes	Subroutine (JSR)	Subroutine used to convert a hexadecimal value to 2-digit decimal (also known by HexToDec). A JSL to this routine can be found at $00974C. Input: -A: 8-bit value to convert Output: -A: 1s digit -X: 10s digit
$009051	40 bytes	Subroutine (JSR)	Subroutine used to convert the player's bonus stars from hexadecimal to decimal, and then write them to the status bar. Note that this only writes them as single-tile 8x8 digits, though; the main status bar's code at $008FAF is responsible for later converting these small digits to the 8x16 numbers actually seen in-game.
$009053	3 bytes	Layer 3	Change to EAEAEA to get rid of the small bonus stars. Use in conjunction with address $00:9068
$009068	3 bytes	Layer 3	Change to EAEAEA to get rid of the small bonus stars. Use in conjunction with address $00:9053
$009079	88 bytes	Sprite tilemap related	Subroutine that draws the power up item to the item box on the status bar during levels. $0090AE is the X position of the Item Box item. $0090B3 is the Y position of the Item Box item. Note: Those two positions are only graphical. It won't change where the item drops from when select is pressed. To change that, see $028052 and $028060
$0090D1	104 bytes	Sprite tilemap related	Tile numbers for 'MARIO START' and various similar messages. $0090EE is for the top half of Time Up. $009122 is for the bottom half of Time Up.
$009139	98 bytes	Sprite tilemap related	YXPPCCCT properties for 'MARIO START' and various similar messages. Change $00913F from 30 to 34 and $009170 from F0 to F4 to fix the S in "Mario/Luigi Start". $009156 is for the top half of 'TIME UP".

$0091DB	1 byte	ASM	Change it to D0 to switch the "Mario/Luigi Start"
$00922F	33 bytes	Subroutine (JSR)	Routine that uploads the entire palette from $0703 to CGRAM. Note that it first resets $0703 and $0704 to $0000 (i.e. turns color 0 to black). This routine is called during various loading screens (Nintendo Presents, level load, overworld load, cutscene load, credits load) but not during gameplay.
$009250	51 bytes	Subroutine (JSR)	Routine that initializes the windowing HDMA parameters. It sets the window to use HDMA channel 7 (or 1, if using SA-1 pack v1.35+) and to use $04A0 as the source. It also initializes that buffer to all $FF00 (i.e. no window is shown). This is only called on game reset.
$0092AE	2 bytes	Misc.	The scanline × 2 of the solid lava colour in the Iggy/Larry boss battle. Change it to $A8,$01 (dw $01A8) to have it begin just where the sprite lava tiles end.

$0093CB	1 byte	Misc.	Blinking Nintendo Presents (0F = 0 time, 1F = 1 time, 2F = 2 times, etc) Also known as Nintendo Presents Brightness (Values use Brightness Register ($0DAE))
$009436	3 bytes	Misc.	Change from [AD 33 14] to [4C 17 94] to disable the circle fade in from Title screen. Use in conjunction with address $009AAD.
$00943B	1 byte	Misc.	How fast the circle right before the titlescreen opens. Default value is 04. The higher the value, the faster it opens. Don't go beyond #$19.
$009451	7 bytes	Palette	Back area colours to use for each castle destruction scene (One byte per movie)
$009459	7 bytes	Palette	Palette row (in the range 00-07) used by the castle in each castle destruction scene. 1 byte per scene.

$00968E	32 bytes	ASM	This is the beginning of the code that is executed for game mode 10 (the black period between fadeout from the OW and Mario Start). $0096A5 is which Layer 1 tile on the overworld will prevent the "Mario Start!" from appearing if the player is on it. (Default is $56, the Yoshi's House tile.) Change $0096A6 to EA EA to make MARIO START! appear on the Yoshi's house OW tile number, or to 80 03 to make the MARIO START! never appear.
$0096AE	158 bytes	ASM	This is the code that is executed by game mode 03 (Load title). Game mode 11 (Mario Start) also uses parts of this code. The shared parts starts at $0096D5. - $0096C4: music bank used for the Title Screen. 0E = Overworld Music, 48 = Level Music, 59 = Ending Music. - $0096C7: title screen (level C7) music. - $0096CC: title screen level number + $24. - $009724: intro screen (level C5) music. - $009725: changing it to [9C FB 1D] will allow you to change the music for the intro via Lunar Magic. - $009737: Bowser scene 1 music.

$009A16	1 byte	Coordinate	Y lo position of Mario at the start of the Morton/Ludwig/Roy battle.
$009A1F	47 bytes	Subroutine (JSR)	Writes the Map16 data for Ludwig/Morton/Roy's boss battle room. $009A40 is what tile the lava tiles in the Morton/Ludwig/Roy battles act like (by default: 05). Only Map16 page 00 is usable.
$009AAD	3 bytes	Misc.	Change from [A9 33 85] to [4C C0 9A] to disable the circle fade in from Title screen. Use in conjunction with address $009436.
$009AB2	1 byte	Misc.	Change to [03] to make all layers appear at the same time during titlescreen load.
$009ACB	76 bytes	Subroutine (JSR)	The cursor routine used in file selection, player selection, and erase file. $009AD3 - If you change this to EA EA EA, the cursor arrow will never be shown in front of the game-start menus. (It will still act as though it were there, though.) $009AE4 - SFX that comes up when you select a game at the title screen. $009AFA - SFX played when you change an option at the title screen and overworld menus.
$009B1D	2 bytes	Palette	BG Palette for the File Erase screen. Original value is $39C9.
$009BBC	1 byte	Sound effect	SFX for saving the game.
$009BC9	74 bytes	Subroutine (JSL)	Save Game function. (Load Game starts around $009CEF. Last byte used in SRAM seems to be $70:0358.)	Documentation
$009C1F	69 bytes	Controller	Mario's movement data on Title Screen. Format: xx yy xx yy xx yy [...] $FF The XXs is the value to store to $15, except that the Select flag (#$20) is instead used to tell if the XY flag (#$40) should be masked away from $16 (if it's set, that bit is stored to $16 unchanged; if clear, that bit is masked away. All other bits are stored to $16.) The YYs is how long to keep that value there. Setting an XX to $FF ends it.
$009C6A	1 byte	ASM	Change to 80 to open save game menu without pressing a button or Title Screen Playing.
$009C82	3 bytes	ASM	Change to [EA A9 00] to remove title screen movement. Title screen will not loop.

$009C9F	4 bytes	ASM	Change from 22 00 80 7F to EA EA EA EA to disable sprites from disappearing on the title screen when pressing a button (opening file select menu)
$009CA9	1 byte	Misc.	Display following layers: ---o4321. o = sprite layer, 4 = layer 4 (unused), 3 = layer 3 (no effect however), 2 = layer 2, 1 = layer 1. Clear the corresponding bits for these layers to not make them display on file select screen load.
$009CAD	3 bytes	ASM	Change '9C 9F 0D' to 'EA EA EA', and, if you happened to have a HDMA effect in the titlescreen, it will not be disabled when you go to the File Menu.
$009CB1	1 byte	Level number	Determines the low byte of the intro level number. Subtract 0x24 for the actual low byte (by default, E9-24=C5, meaning level C5, or possibly 1C5 with Lunar Magic's Display Level Message 1 fix). Change to [00] to skip the intro level and warp to the overworld immediately.
$009CCB	3 bytes	Misc.	SRAM starting addresses for each of the three save files, high byte.
$009CCE	3 bytes	Misc.	SRAM starting addresses for each of the three save files, low byte.
$009CD4	2 bytes	Palette	BG Palette for File and Player Select screens. Original value is $7393.
$009CD7	4 bytes	Sprite tilemap related	Y displacement for tiles in the first shared GFX routine ($019CF3).
$009CDB	24 bytes	Sprite tilemap related	Properties for tiles in the first shared GFX routine ($019CF3). It's indexed by the value of $05 times 4.
$009D30	8 bytes	Subroutine (JSR)	Subroutine used for changing the background color on the titlescreen, when entering/exiting the file erase menu. To use, load the color (16-bit) to A and a CGADDSUB value (for half-color math) to Y first.

$009E74	10 bytes	Stripe Image	Table containing the stripe image header (see here for more info) for the cursor in various menus. The entries are as follows: - $51CB: unused - $51E8: file select menu - $5208: player select menu - $51C4: unused - $51E5: file erase menu
$009E7E	4 bytes	Misc.	Table of four bitwise values ($01,$02,$04,$08) indexed by $1B92 and used in the cursor draw routine to determine on which row to actually draw it.
$009E82	94 bytes	Subroutine (JSR)	Routine that draws the cursor on the screen for different menus (file select, player select, file erase). It uses $1B92 to determine on which row to draw it, and $1B91 to skip drawing it every so often to create the blinking effect. $009EBA ($FC) holds the tile that's drawn in the rows that aren't supposed to show the cursor. $009EBB ($38) holds its YXPCCCTT properties. $009EC1 ($2E) holds the cursor tile number. $009EC2 ($3D) holds its YXPCCCTT properties.
$009EE0	16 bytes	Overworld	Initial level flags. This table is made of a pair of bytes where the first byte contains the translevel number and the second byte the overworld level settings. In an LM-modified ROM, this table is unused, with the initial flag data instead being loaded from a table at $05DDA0 that just contains one byte per translevel.
$009EF0	22 bytes	Overworld	Initial overworld position data for Mario and Luigi, corresponding to addresses $1F11 through $1F26. The values are copied there on creation of a new save file.
$009F06	35 bytes	Subroutine (JSR)	Routine to initialize RAM for a new save file. This first clears the SRAM buffer at $7E1F49, then loads into it the initial level flags (using the table at $009EE0) and initial overworld positions for both players (using the table at $009EF0).
$009F2A	1 byte	Misc.	Speed of Fade-ins and Fade-outs.
$009F2F	1 byte	Overworld border	Change from 01 to 0F to stop fadeout on entering level, new area, and back to submap. (Use with $00:9F59)
$009F37	81 bytes	Subroutine (JSR)	Fading/mosaic routine. Change $009F59 from D0 to 90 to eliminate all fadeouts. (use in conjunction with $009F2F). Mod note: I've heard that this one is buggy. Use on your own risk. $009F67 controls which layers are affected by the mosaic effect. Format: xxxx4321. The numbers present the layer numbers to add mosaic on. So 1 = Layer 1, 2 = Layer 2, etc.
$009F88	48 bytes	Layer 3	Layer 3 settings. The table is indexed by 3t + i, where t is the tileset number and i is the Layer 3 image setting (00 = variable tide, 01 = low tide, 02 = tileset-specific image). It is used by the routine at $009FB8. The actual format seems to be: 01 = variable-height tide 02 = fixed-height tide 80 = Layer 3 smashers/cage 81 = slow-auto-scrolling background (except in tilesets 1 and 3, where it will be a background that scrolls at half the rate Layer 1 does) C0 = same as 80, except without the smasher palette
$009FB8	141 bytes	Subroutine (JSR)	The main Layer 3 handling routine in levels. - $009FDA: Starting Y position of the rising/lowering tide. - $009FDF: Y position of the fixed-height tide. - $009FF3: One of two tilesets for which the tileset-specific Layer 3 background will not auto-scroll. The other is at $009FF7. - $009FF7: One of two tilesets for which the tileset-specific Layer 3 background will not auto-scroll. The other is at $009FF3. - $00A00A: Pointer to the layer 3 crusher palette.
$00A045	38 bytes	Layer 3	The routine that sets the interaction of the Layer 3 tide tiles. Both $00A04E and $00A04F are the low byte of the Map16 tile that the tides act like; nothing is stored to the high byte, so this is always on page 0.
$00A06B	14 bytes	Coordinate	16-bit X-coordinates for each of the seven submaps. The main map has values of 0, and is overridden elsewhere.
$00A079	14 bytes	Coordinate	16-bit Y-coordinates for each of the seven submaps. The main map has values of 0, and is overridden elsewhere.
$00A09C	1 byte	Timer	Timer to disable skipping the intro message (level C5). The timer decreases every 4 frame.
$00A0CC	3 bytes	Misc.	Saves Mario/Luigi's powerups based on which one you are using for the level
$00A0F9	1 byte	ASM	Part of the routine that runs after dying with zero lives. If # of levels beat is zero, then it will take you back to the intro screen, if levels beat is positive, it will take you back to the last place you saved on the OW and bring up the Continue/End dialog. Change this byte to BRA ($80) to cause it to not send you to the intro screen and bring up the Continue/End dialog if you haven't saved for the first time. (In other words, it will take you back to Yoshi's House on an unedited overworld.)
$00A148	1 byte	Overworld	GFX file for animated tiles (waterfalls etc) on the overworld.
$00A15A	4 bytes	Overworld border	Call to the routine to draw the number of lives on the overworld border. Change to [80 02] (BRA $02) to disable the amount of lives from being shown in the overworld border. Use with $04A530.
$00A1E3	1 byte	ASM	Change to 0xEA to keep the game running when a message box is on the screen.
$00A21E	1 byte	Controller	Button to press for Pause. (Checks $16)
$00A21F	1 byte	ASM	Change from F0 (BEQ) to 80 (BRA) to disable pausing
$00A22D	1 byte	Timer	Timer (in frames) that runs to prevent the pause flag from being flipped instantly. Change [3C] to another value to change the time it takes for Mario to pause/unpause.
$00A23E	1 byte	Music	Change to 12 and music will continue to play when you pause the game. Changing [11] to another value will alter the sound effect that occurs when pausing the game.
$00A248	1 byte	Debug	DEBUG: Advance frame / Slow motion (00 = enable)
$00A256	1 byte	Debug	DEBUG: Slow motion speed
$00A25B	47 bytes	Controller	Code to handle leaving the level with Start+Select. Change $00:A268 to 00 to always allow leaving the level. Change $00:A273 to 00 to beat the level by doing that, not just leave it. Holding A or B will give the secret exit.
$00A300	144 bytes	Subroutine (JSR)	The routine that handles the graphics that get DMA'd to the first five 16x16 tiles in SP1. It also write the necessary colors to the player's palette (colors 6-F). $00A30A - Mario/Luigi Palette - Starting Index (Changing this will cause Mario/Luigi to flash when the screen fades out after beating a boss) $00A320 - Mario/Luigi Palette - Amount of colours * 2 $00A307 - [F0] Changing this to [80] will skip the player's palette write code, removing palette 8's hardcoded colors.
$00A390	1 byte	ASM	[C2] Change to 60 to disable all animations in levels. This includes colour 64. Note: LM will still show the animations.
$00A3DB	2 bytes	Overworld border	[00 08] For which VRAM address animation data will be broken up into two lines of two tiles instead of a single line of four tiles.
$00A400	2 bytes	Overworld border	[00 09] VRAM address of the second line of two animated tiles (value should be $00A3DB + 0x100).
$00A41A	1 byte	Palette	[A9] Changing this to 60 will disable the flashing yellow color in levels, but not on the overworld.
$00A41B	1 byte	Palette	Palette number to use for the flashing palette. Default value is $64
$00A429	12 bytes	Palette	Changing [B9 0C B6 8D 22 21 B9 0D B6 8D 22 21] to [80 0A EA EA EA EA EA EA EA EA EA EA] will disable the flash animation of colour #64. Make sure that the "View Animation" function in Lunar Magic is disabled. WARNING: Will disable the animated colours on the OW too!
$00A439	1 byte	Misc.	Change [F0] (BEQ) to [80] (BRA) to prevent various tiles in SP1 to be overwritten (which meant using ExGFX for them would have no effect). This does not affect tiles 00-09, 10-19 and 7F of SP1.
$00A514	1 byte	Palette	The first animated colour on the overworld. (Default: 6D.)
$00A51D	1 byte	Palette	The second animated colour on the overworld. (Default: 7D.)
$00A635	353 bytes	ASM	Routine responsible for initializing various things during loading of levels and castle destruction cutscenes. This includes: - Resetting P-switch, star, and directional coin timers, as well as resetting their music. - Controlling the flag for whether the coinblock bonus room minigame is still playable. - Clearing RAM addresses $71-$93 and $13DA-$1410. - Preventing Yoshi from spawning if the level has a No-Yoshi entrance. - Preparing Mario's entrance action (as defined by $192A) for both regular levels and No-Yoshi entrances. $00A6B6: Initialization of a No-Yoshi level. $00A6CC: Initialization of a regular level.
$00A757	1 byte	Misc.	How far to offset the players position to the right when exiting a vertical pipe. Values above 0F aren't recommended.
$00A75F	1 byte	Misc.	How many frames to move Mario when exiting upward from a vertical pipe.
$00A763	1 byte	Misc.	How many frames to move Mario when exiting downward from a vertical pipe while small.

$00BA60	32 bytes	Pointer	The low byte of a series of Map16 data pointers in horizontal levels. The high bytes are at $00BA9C, and the bank byte is either $7E or $7F. These are indexed by screen number; each byte in this table and the other corresponds to the start of a particular screen's Map16 data (or chunk of 0x1B0 bytes). These are used in various routines that read or write Map16 data to find where a particular tile is.
$00BA80	28 bytes	Pointer	The low byte of a series of Map16 data pointers in vertical levels. The high bytes are at $00BABC, and the bank byte is either $7E or $7F. These are indexed by screen number; each byte in this table and the other corresponds to the start of a particular screen's Map16 data (or chunk of 0x200 bytes, which means that all of these will be 00 in a clean ROM anyway). These are used in various routines that read or write Map16 data to find where a particular tile is.

These are indexed by screen number; each byte in this table and the other corresponds to the start of a particular screen's Map16 data (or chunk of 0x200 bytes, which means that these are all simply multiples of 2 plus #$C8). These are used in various routines that read or write Map16 data to find where a particular tile is.
$00BEB0	268 bytes	Subroutine (JSL)	SMW's Map16-tile-generating routine. It uses values of $9C to determine which tile to generate, but these values are hardcoded. (See RAM address $9C.) This is the main part; $00BFBC runs the codes for each tile.
$00BFBC	67 bytes	Subroutine (JSR)	A subroutine used with $00BEB0; it runs different codes depending on the value of $9C. The pointers for the different values begin at $00BFC9. They go from 01 to 1B, although the actual codes are kind of weird...the pointers vary depending on which Map16 page the tile is on, whether or not item memory should be affected, and if there are special cases (such as the Yoshi coin, which generates two tiles simultaneously).
$00C00D	86 bytes	Subroutine (JSR)	The subroutine that sets item memory bits. It is called during the subroutine at $00BEB0 for values of $9C that utilize item memory.
$00C06B	9 bytes	Misc.	Tiles to generate on Map16 page 0, used for values 01-09 of $9C. Note that the first byte is unused.
$00C074	54 bytes	Subroutine (JSR)	SMW's subroutine for generating tiles on Map16 page 0. $00C077 is an alternate entry point to this routine; if it is used instead, then the tile generation will not affect item memory.
$00C0B2	15 bytes	Misc.	Tiles to generate on Map16 page 1, used for values 0A-17 of $9C.
$00C0C1	58 bytes	ASM	A portion of code used in SMW for generating tiles on Map16 page 1. $00C0C4 is an alternate entry point to this routine; if it is used instead, then the tile generation will not affect item memory.
$00C0FB	177 bytes	ASM	The portion of code in SMW's Map16-tile-generating routine that changes the actual graphics of the tile. Both $00C074 and $00C0C1 use it (the former jumps to it, and it immediately follows the latter).
$00C29E	72 bytes	Misc.	BG Tiles/Palette for Flipped Gate (1)
$00C2E6	72 bytes	Misc.	BG Tiles/Palette for Flipped Gate (2)
$00C4AF	1 byte	Misc.	If you change this byte from [02] to [01], the keyhole will activate the normal exit.
$00C526	1 byte	Music	Music played when you have completed the Bonus Game.
$00C558	1 byte	Sound effect	POW Finishing Sound Effect.
$00C570	1 byte	Misc.	[F0] Change to [80] to make the item not drop when the player presses Select.
$00C576	1 byte	Debug	DEBUG: Powerup select (F0 = enable)
$00C599	28 bytes	Pointer	Pointer to Mario's animation routines. ($7E0071)
$00C5CE	3 bytes	ASM	[9C 9F 0D] This address disables HDMA effects when player animation #$0B (Freeze) is triggered. To fix this, change to [EA EA EA] (NOP #3).
$00C5E8	248 bytes	Misc.	Movement data for all of the castle destruction scenes. Each data entry consists of two values, the first being the command and the second being the number of frames to keep that command active. If bit 4 of the command byte is set, question marks will be drawn above Mario (as in Roy/Ludwig's scenes). If bit 5 is clear, the rest of the byte is read as input data for $15/$16. If bit 5 is set, then the first four bits are used to run additional commands. x0-x6 will run a variety of small routines, while x7-xF will change Mario's pose. If #$2D, the P-balloon sound will also be played (for Lemmy's). Lastly, #$FF marks the end of that scene's data.
$00C6E0	7 bytes	Misc.	Base indices to the data at $00C5E8 for each of the castle destruction scenes.
$00C848	40 bytes	Controller	Table that holds controller input data for the No Yoshi cutscenes, used by the routine at $00C870. The table is divided in two parts: the first (15 bytes) is used when the player doesn't have a Yoshi, the second (25 bytes) is used when there's Yoshi. The table is formatted as a sequence of two bytes chunks: the first is used as the input data, which first is ANDed with #$DF and then copied to $15 (so the third highest bit is ignored). When the value equals #$20, #$80 is stored to $18, to force an A press and dismount Yoshi. Instead, when the value has the second highest bit set (#$40), the entrance door starts animating. The second byte is the number of frames that the current input will be used, before passing on to the next. $88 is used as an index for the current entry being used, while $89 is used for the timer. Both parts of the table end with a $FF byte which makes the cutscene end when reached.
$00C870	165 bytes	Subroutine (JSR)	Routine that handles No Yoshi cutscenes, run whenever $71 is #$0A. The routine first sets up sprite data depending on the current cutscene type (ghost house, rope or castle). Then, it checks if A or B are pressed: in this case, the cutscene ends immediately. Otherwise, the player's controls are disabled, and the player's movement is handled by using the table at $00C848 (follow the link for more details on this). The entrance door animation is handled once a certain value in the table (#$40) is reached. During the entire process the code at $00CD82 is jumped to to handle some of Mario's physics (jump, cape spinning, throwing fireballs, cape flying) and animations. Once the value #$FF is read from the table (or the player presses A/B), the cutscene ends and the gamemode is changed to #$0F (fade to level).
$00C92C	2 bytes	Misc.	[F0 3D] Change to [EA EA] to prevent Mario walking after touching goal spheres or the goal tape.
$00C9A7	8 bytes	Level number	The level numbers that triggers the seven castle destruction sequences and the credits scene. The first byte is for scene 1, the second is for scene 2, and so on, while the last byte is for the level which triggers the credits (specifically, as Front Door; back door can be found at $00CA13).
$00C9BD	1 byte	Music	Goal point fade-out music
$00C9FE	3 bytes	ASM	[8D D5 0D] The code itself stores either 01 or 02 to $0DD5. Change to [EA EA EA] to make it possible to set the normal/secret exit info through $0DD5 via LevelASM, sprites, etc. (Note: To activate any exit at all, $0DD5 has to be explicitly set to 01, 02, 03 or 04. Leaving it as 00 will cause no exit to be activated at all, and values 05-FF should not be used.)
$00CA0C	1 byte	Level number	Translevel number of the level where defeating a boss will activate the secret exit.
$00CA12	2 bytes	Misc.	[C9 31] Changing this to [80 11] will prevent any "boss defeated" scenes from ever being played. $00CA13 is one of the two level numbers that triggers the credits scene. The other is at $00C9AE.
$00CA2C	1 byte	Misc.	Set to 00 to disable midway points (they'll still make you big though)
$00CA31	13 bytes	Subroutine (JSR)	Set the "peace" pose for the player depending on whether they're on Yoshi or not.
$00CB0C	1 byte	ASM	Change from '8D' to '0C' to not make HDMA gradients act strangely at the end of the level (goal tape). Of course, you should still avoid using HDMA channel 7 if this is all you change.
$00CB12	258 bytes	Misc.	Opening window data. $00CBA3 - Change 4B to 49 to fix a misplaced tile on the keyhole "iris in" effect.
$00CC84	1 byte	Debug	DEBUG: Change from [$80] to [$F0] to enable free roam mode. When enabled, hold A and press L to cycle the mode between normal, P-speed, and no-clip. See $7E1E01 for more details.
$00CC85	1 byte	Debug	Change this to 00 and you'll activate free roaming mode (just like $00CC84)
$00CD4E	4 bytes	ASM	[AD 8F 14 0D] Change to [EA EA EA AD] to enable climbing while holding an item
$00CD5F	1 byte	Mario physics	Change from [15] to [16] so you don't automatically grab whatever you are climbing (vine, net, etc.) again if you happen to still be holding up/down. Instead after you jump it will let go and let you jump until you press up/down again.
$00CDA9	4 bytes	Misc.	Mario riding on Yoshi animations
$00CDC5	1 byte	Misc.	Animation frame for Mario crouching on Yoshi
$00CDF6	131 bytes	Subroutine (JSR)	L & R scrolling routine. Change $00CDFC from D0 to 80 to disable L & R scrolling. Or change to [EA EA] to allow scrolling even if the player is holding multiple buttons (works best if $00CE12 is set to 01). $00CE12 is the number of frames L or R must be held before screen scrolling occurs. $00CE40 is the screen scroll sound effect.
$00CE99	8 bytes	Mario tilemap	Spin Jump frame table (00 00 - Mario Standing - Small - Big) (25 44 - Mario Back to Screen - Small - Big) (00 00 - Same as first) (0F 45 - Mario Facing Screen - Small - Big) They are indexed by the frame counter.
$00CEA1	8 bytes	Mario tilemap	Spinjump direction table.
$00CEA9	8 bytes	Mario tilemap	Cape spin cape image table. These are run while spin jumping with a cape or doing a spin attack. Only these four cape images ($02,$07,$06,$09) seem to work with cape contact, and will only work if RAM $14A6 is above zero.
$00CEB1	387 bytes	Subroutine (JSL)	The code that updates the player and cape poses, and sets them to $13E0 and $13DF. It also updates certain other related things such as flipping mario's direction when spinjumping.
$00CEBE	1 byte	Mario physics	Amount of frames to show the cape at highest altitude frame. (After, for example, a spin-jump has been done.)
$00CF42	1 byte	Mario physics	Power-up that can attack with both cape spin and spin jump

$00CFCA	1 byte	Controller	Which button to press to look up. (Look at Ram Address $7E:0015 for values).
$00CFCB	1 byte	Mario physics	Change from [F0] to [80] to disable looking up.
$00CFCE	1 byte	Mario tilemap	This is the player looking up pose, the default is #$03.
$00D034	8 bytes	Mario physics	Cape Collision X (Horizontal) Offsets: Two bytes for right and left, on ground and in air. The first two sets are for when Mario is on the ground while spinning ($0C,$00- right; $F4,$FF left), and the second two are while he is in the air ($08,$00 - right; $F8,$FF - left) The first byte in each set determines the position per pixel, the second sets whether it is in front or behind him ($FF is behind, $00 is in front) Use $FF-$80 for the behind byte($FF), and $00-$79 for the in front byte ($00) This does not effect the image offsets.
$00D03C	8 bytes	Mario physics	Cape Collision Y (Vertical) Offsets: 2 bytes for right and left, on ground and in air. The first two sets are for when Mario is on the ground while spinning ($10,$00 - right; $10,$00 - left), and the second two are while he is in the air ($02,$00 - right; $02,$00 - left) The first byte in each set determines the position per pixel, the second sets whether it is above him or below him ($FF is below his feet, $00 is from his feet up) Use $FF-$80 for the below byte ($FF), and $00-$79 for the above byte ($00) This does not effect the image offsets.
$00D044	30 bytes	Mario physics	Routine that does the actual calculation for cape-interaction. Uses the two tables at $00:D034 and $00:D03C.
$00D062	31 bytes	Subroutine (JSR)	Cape Swing routine. $00:D065 controls which power-up the player needs to have to be able to cape spin. Change $00:D067 to 00 to make mario cape spin in all forms. $00:D077 controls how long Cape Spin lasts. $00:D07C controls the cape spin sound effect to generate.
$00D081	45 bytes	Subroutine (JSR)	Fireball throwing routine. $00D082 is the power-up that can throw fireballs. Change $00D084 to 00 to let Mario throw fireballs in all forms. Change $00D085 from A5 73 to A9 00 to enable throwing fireballs while ducking. Change $00D087 from 0D 7A 18 to EA EA EA to enable throwing fireballs while on Yoshi. Change $00D08A to 80 do disable throwing fireballs. Change $00D093 from F0 to 80 to disable throwing fireballs while spin jumping.
$00D0B9	1 byte	Mario tilemap	Mario death pose (uses RAM $13E0)
$00D0D5	3 bytes	ASM	Set 9C C1 0D to EA EA EA in order to not lose Yoshi on the OW when you fall down a pit when on top of Yoshi.
$00D0D8	3 bytes	ASM	ASM that handles losing lives. Change to [EA EA EA] to not lose a life after dying. Change to [80 03 EA] to always go to the Game Over screen when dying.
$00D0DE	1 byte	Music	Game Over music
$00D0F1	1 byte	ASM	ASM that handles the 'TIME UP!' message. Change 'D0' to '80' to disable it.
$00D0F8	10 bytes	Misc.	Controls timer for TIME UP/GAME OVER message. Change $00D0F9 from C0 to 00 to remove the animation, and change $00D0FE from FF to whatever you want to shorten the timer (however, 00 is as long as FF; 01 is the shortest).
$00D11A	1 byte	ASM	Change [85] to [60] and Mario will not flip X-wise when he dies.
$00D11D	12 bytes	Mario tilemap	Mario Shrinking Animation poses (uses RAM $13E0).
$00D141	1 byte	Timer	How long flashing invincibility (when you get hit) lasts
$00D156	5 bytes	ASM	Change to EE E4 18 EA 64 to turn the Mushroom into a 1up, but it'll still play the animation
$00D18D	6 bytes	Mario physics	Speed at which Mario enters/exits a pipe. The first two bytes are horizontal speed when entering/exiting a horizontal pipe. The next two bytes are both horizontal speed in vertical pipes, and vertical speed in horizontal pipes. The last two are the vertical speed in vertical pipes.
$00D1AE	1 byte	Misc.	Animation frame for Mario entering horizontal pipe on Yoshi
$00D20A	1 byte	Mario tilemap	Mario's pose for entering a vertical pipe (Default is 0F - facing screen)
$00D229	1 byte	Misc.	Animation frame for Mario entering vertical pipe on Yoshi
$00D231	5 bytes	Mario tilemap	Change (A9 02 8D F9 13) to EA EA EA EA EA to remove Mario's priority when he's going into a pipe.
$00D255	1 byte	Sound effect	Mario emerge from vertical pipe Sound Effect.
$00D2BD	16 bytes	Mario physics	Mario's jump height. The earlier ones are when Mario is moving slowly (or standing still); the latter is when he's moving faster. Even entries are normal jump, odd are spin.	Formula
$00D2CD	60 bytes	Mario physics	Player deceleration table for each type of slope, in the order of $13E1. This table contains two 16-bit values for each slope type to accelerate/decelerate the player towards the slope's base speed (see $00D5C9). The first value is used when the X speed is above the slope's base speed (so decrease the player's X speed) while the second is used when below the slope's base speed (so increase it). The first two entries of this table (for flat ground) are also used when Mario is swimming as well. Additionally, they get used when the player is not on the ground, but is above their maximum X speed and left/right is being held. When on the ground in a slippery level, the table at $00D309 is used instead.
$00D309	60 bytes	Mario physics	Player deceleration table in slippery levels for each type of slope. For more details on its format, see its non-slippery variant at $00D2CD.
$00D345	104 bytes	Mario physics	Accelerations for Mario in a non-slippery level, or in a slippery level while in midair. The table is split into sets of four 16-bit values each, in the order of $13E1. The values in these sets are ordered as: walking (no X/Y) left, running (X/Y held) left, walking right, running right.
$00D3AD	16 bytes	Mario physics	Accelerations for Mario when flying. Consists of 16-bit values in two sets (facing left/right) of two groups (moving left/right) with two values each (no X/Y and X/Y held).
$00D3BD	24 bytes	Mario physics	Sliding accelerations on slopes in a non-slippery level. Each value is 16-bit, in the same order as $13E1 (excluding flat ground).
$00D3D5	104 bytes	Mario physics	Turning decelerations for Mario in a non-slippery level, or in a slippery level while in midair. The table is split into sets of four 16-bit values each, in the order of $13E1. The values in these sets are ordered as: walking (no X/Y) left, running (X/Y held) left, walking right, running right.
$00D43D	104 bytes	Mario physics	Accelerations for Mario in a slippery level. The table is split into sets of four 16-bit values, in the order of $13E1. The values in these sets are ordered as: walking (no X/Y) left, running (X/Y held) left, walking right, running right.
$00D4B5	24 bytes	Mario physics	Sliding accelerations on slopes in a slippery level. Each value is 16-bit, in the same order as $13E1 (excluding flat ground).
$00D4CD	104 bytes	Mario physics	Turning decelerations for Mario in a slippery level. The table is split into sets of four 16-bit values, in the order of $13E1. The values in these sets are ordered as: walking (no X/Y) left, running (X/Y held) left, walking right, running right.
$00D535	104 bytes	Mario physics	Mario's maximum X speeds on flat ground and on slopes. The table consists of sets of 8 bytes, in the order of $13E1. Each of these sets then consists of four groups of two bytes each (for max left and max right), in the order: walking, running, running fast, sprinting. The "running fast" values get used when running faster than #$23 (defined at $00D723) and either on the ground or shot out of a diagonal pipe.
$00D59D	16 bytes	Mario physics	Mario's maximum X speeds while flying. The first 8 bytes are facing right, the second 8 are facing left. Each of these sets are split into four groups of two bytes each (for maximum left and right speeds). Only the first two groups are actually used, for flying without X/Y and flying with X/Y respectively. Also, in case it's not clear, the maximum speeds in the direction opposite of Mario's are from pressing that direction with B to slow down (e.g. <+B when facing right).
$00D5AD	16 bytes	Mario physics	Mario's maximum X speeds in water. The first set of 8 bytes is for when Mario isn't carrying an item, while the second set is with one. Each set consists of four groups of two bytes each (for max left and max right), in the order: on ground, swimming, on ground in a tide, swimming in a tide.
$00D5BD	12 bytes	Mario physics	Mario's maximum X speeds when sliding down slopes with the down button. In the order of $13E1, without flat ground or flying included.
$00D5C9	26 bytes	Mario physics	Base X speeds (16-bit) for the player when standing on each type of slope, in the order of $13E1. When the player is standing on a slope without holding left or right, the game will accelerate/decelerate them towards the slope's corresponding value here. See $00D2CD for corresponding acceleration speeds.
$00D5E7	2 bytes	Mario physics	Value added to the player's X speed as they're floating in water freely in a level where a Layer 3 tide is active. The value is 16-bit, with the high byte corresponding to Mario's regular X speed ($7B), and the low byte corresponding to the accumulating fraction bits ($7A).
$00D5E9	2 bytes	Mario physics	Value added to the player's X speed as they're in water and on the ground in a level where a Layer 3 tide is active. The value is 16-bit, with the high byte corresponding to Mario's regular X speed ($7B), and the low byte corresponding to the accumulating fraction bits ($7A).
$00D603	1 byte	Controller	Which button to press to duck. Format: byetUDLR; b = A or B; y = X or Y; e = select; t = Start; U = up; D = down; L = left, R = right.
$00D604	1 byte	ASM	Change from F0 (BEQ) to 80 (BRA) to disable ducking. Note that setting $01EB16 to [EA EA A5 73] (NOP #2 : LDA $73) is a good idea if you're using this.
$00D61C	2 bytes	ASM	Change from 30 12 to EA EA to disable jumping.
$00D63E	1 byte	ASM	Change from 10 to 80 to disable Spin Jump.
$00D644	1 byte	Mario physics	[19] Change to [00] to allow Mario to spin jump while carrying an item. Because Mario spins so fast, the animation will not be smooth.
$00D645	1 byte	ASM	Change this from "1A" to "60" to disable spin jumping. Unlike 0583E (SNES $00:D63E) from "10" to "80", changing this address does not make the "A" button do the regular jump, but it disables spin jumping altogether. This way, you can use the "A" button for something else without it jumping automatically. Note: Still allows you to spinjump out of the water and dismount Yoshi.
$00D64A	1 byte	Misc.	Spin Jump Sound, uses bank 1DFC.
$00D65E	10 bytes	ASM	Mario jumping routine. (Sound effect + store to Mario Y speed.) $00D65F is the Sound effect for Mario jumping. $00D661 is the bank for the sound effect. By default it uses $1DFA, but you can make it use $1DFC by changing $00D661 to FC or $1DF9 by changing it to F9.
$00D66F	1 byte	Mario physics	Change to 80 to disable Cape Flight and Jumping High while dashing. Interestingly enough, changing it to A9 will make Mario do a dash jump with every jump, even at a standstill, and will allow him to gain speed in the air. In addition, doing so will have the effect of causing every Jump performed by Cape Mario to become a Cape Flight.
$00D674	1 byte	Mario physics	[D0] Change to 80 to prevent the player from flying with a cape. The player will still be able to float, cape-spin, and jump higher when running but will never "take off".
$00D677	1 byte	Mario physics	Mario fly time
$00D707	1 byte	Mario tilemap	[0D] Mario's turning(skidding) pose
$00D717	1 byte	ASM	Change [50] to [80] to disable running and cause Mario to never run. The Y (or X) button will not cause Mario to run. This does not affect other uses of the Y button, like shooting fireballs or carrying sprites.
$00D718	1 byte	Mario physics	Change [1E] to [00] to cause Mario to always run, as if the Y button is always down. This does not affect other uses of the Y button, like shooting fireballs or carrying sprites. Also, Cape Mario will still need the Y button to fly.
$00D72C	1 byte	Misc.	Number of frames Mario should continue to show his running frames for after jumping.
$00D7A5	3 bytes	Mario physics	Gravity. The first byte is when not holding B (or A), the second is gravity when holding B/A, and the third is when riding on a winged Yoshi.
$00D7AF	1 byte	Mario physics	Falling maximum speed (without button held)
$00D7B0	1 byte	Mario physics	Falling maximum speed with button held
$00D7B9	1 byte	Mario physics	The speed at which Mario falls with a cape. Set it lower to make him float slower, higher to float faster, and over D0 to enable unlimited jumping in midair with the cape.
$00D7BA	1 byte	Mario physics	Flight acceleration (added to y speed)
$00D7C8	7 bytes	Mario physics	Maximum falling speed for cape mario, index by RAM address $1407 (cape phase).
$00D7CF	6 bytes	Mario physics	cape speed
$00D805	1 byte	Mario physics	Power-up that can fly
$00D8EA	1 byte	Misc.	power-up that can float (cape by default)
$00D905	1 byte	Mario physics	change to 16 = Raccoon Mario (floating if you tap Y instead of holding it)
$00D909	1 byte	Mario physics	Time until you stop floating after you have pressed B while while in the air with a cape.
$00D972	1 byte	Mario physics	Change to 00 to disable sprinting after running on the ground for a long period of time. Note that cape flight will also be disabled as a consequence.
$00D998	1 byte	ASM	Change this from [F0] (BEQ) to [80] (BRA) so that when the player is carrying an item while swimming, his Y speed won't be affected (the player will sink normally). Also, if you change this to [D0] (BNE), the player will float if carrying nothing and sink if carrying an item.
$00D9D0	1 byte	Mario physics	Maximum sinking speed of player when holding an item while swimming. When adjusting this value, it's recommended that it's equal to x5BD4. Format of RAM $7E007D.
$00D9D4	1 byte	Mario physics	Maximum sinking speed of player when holding an item while swimming. When adjusting this value, it's recommended that it's equal to x5BD0. Format of RAM $7E007D.
$00D9D8	1 byte	Mario physics	Maximum rising speed of player when holding an item while swimming. When adjusting this value, it's recommended that it's equal to $00D9DC. Format of RAM $7E007D.
$00D9DC	1 byte	Mario physics	Maximum rising speed of player when holding an item while swimming. When adjusting this value, it's recommended that it's equal to x5BD8. Format of RAM $7E007D.
$00DA37	1 byte	ASM	Change to 80 to disable ducking underwater, can be used in conjunction with $00D604 hex edit.
$00DA55	84 bytes	Mario physics	Mario's horizontal water interaction routine.
$00DA8E	1 byte	Mario tilemap	Shooting fireball while swimming pose. Default is #$18 (Swimming pose 3)
$00DAAA	1 byte	Sound effect	Sound effect that plays when you press the button to swim
$00DAB7	1 byte	Mario physics	Vine climbing speed 1 (right and down)
$00DAB9	1 byte	Mario physics	Vine climbing speed 2 (left and up)
$00DB9A	1 byte	ASM	[10] Change to 80 to disable jumping while climbing.
$00DBA6	1 byte	Sound effect	Sound effect to play when jumping while climbing. The bank it stores to is located at $00DBA8 [$1DFA by default] and can be changed to $1DF9 or $1DFC.
$00DBB3	1 byte	Sound effect	Sound effect played when Mario hits a net. (1DF9)
$00DC2D	75 bytes	Mario physics	Routine that updates the player's X and Y position ($94/$13DA and $96/$13DC) using their X and Y speed ($7B and $7D). The player's speed is actually measured in units of "subpixels" corresponding to 1/16th of a full pixel. So a speed of $10 will increase his position by 1 pixel per frame, while a speed of $08 will increase his position by 1 pixel every 2 frames.
$00DC78	4 bytes	Misc.	Number of animation frames to use for walking/running Mario, indexed by Mario's status. Ex: db $01,$02,$02,$02 The first byte it for small Mario, next is Super (Big) Mario, then Cape Mario, and finally Fire Mario. $01 means 2 frames for small Mario and $02 means 3 frames for the others. Longer animations are possible, but that'd require moving stuff around in $13E0, which hasn't been researched yet.
$00DC7C	112 bytes	Mario tilemap	Animation rates for both Mario's run animation and his cape animation (as it's flapping in the "wind" from running). Indexed by the absolute value of Mario's X speed divided by 8, plus $13E5 (which holds a multiple of 8). Index = \|MarioXSpeed\| / 8 + $13E5	Byte structure
$00DD4E	228 bytes	Mario tilemap	X positions of Mario's tiles in various poses, two bytes per tile.

$00E18C	2 bytes	Palette	This is a two byte table used to index the player's palette based on the direction the player is facing.
$00E18E	70 bytes	Mario tilemap	Cape tilemap indices. That table controls the additional tiles used by the cape powerup, indexed by $7E13E0.
$00E1D4	70 bytes	Mario tilemap	Miscellaneous table to the cape tiles. The values in the table is indexed by $00E18E which in turn is indexed by $7E13E0. Stored in this order are the hidden tiles flags (see $7E0078 for more information), 3rd player tile / cape image (equivalent to the tile number on page 9 in Lunar Magic), index to the 3rd tile offset, index to the 8x8 tile image (same formula as with 3rd image) and index to 8x8 tile number. The data has got no clear separation (that is, multiple tilemap data are interleaved) and indices can only be derived from $00E18E. Note that if the third tile image is loaded, values 0x00 - 0x03 is used together with $7E13DF × 4 as an index to the tables $00E23A and $00E266 instead.
$00E23A	44 bytes	Mario tilemap	Cape tile map
$00E266	44 bytes	Mario tilemap	cape offsets
$00E292	16 bytes	Misc.	Table used to determine when to draw Mario while he is flashing (when being hurt). It's set up so Mario will blink faster as the invulnerability timer gets closer to 0. Indexed by $1497 divided by 8, it determines how frequently Mario will be drawn on screen (lower values = more frequently), but in some situations he will be drawn nonetheless (specifically, when $9D or $13FB are set). The values in the table should all be powers of 2.

$00E4FB	33 bytes	Mario physics	Y speeds to give Mario when moving up various slope tiles (i.e. towards its "peak"). These values are ordered the same way as $00E4B9, though the "flat ground" value is unused.
$00E51C	33 bytes	Misc.	Sizes of the "top" area on various slope tiles; if Mario is moving downwards while within this distance from the top of the ledge/slope, he will be pushed on top of it. These values are ordered the same way as $00E4B9.
$00E53D	33 bytes	Misc.	Values stored to $13EE/$15B8 for each slope tile. These values are ordered the same way as $00E4B9, although the upside-down slope values actually do get used (perhaps unintentionally) for fireballs.
$00E55E	106 bytes	Misc.	Indices to the tables at $00E4B9-$00E53D and $00E632, when in any tileset except 0 and 7 (used for upside-down slopes). This table is indexed by Map16 tile number, for the range 16E-1D7. An index to this table is stored at $82.

$00E632	512 bytes	Misc.	Values stored to $1694 for slopes, to indicate how far the top of the slope is from the top of the actual tile at any given X position; essentially, these values define the actual shape of each slope. The indices to this table are the same as $00E4B9 (excluding flat ground), except multiplied by #$10 and with the sprite's X position within the tile (from $9A) added to it.
$00E913	12 bytes	Mario physics	Table of X speeds that conveyors push Mario with. Each 16 bit value refers to one type of conveyor: - $0001: flat right. - $FFFF: flat left. - $0001: up right. - $0001: down right. - $FFFF: up left. - $FFFF: down left.

$00EBDD	68 bytes	Mario physics	Door interaction routine. Handles boss doors, normal doors and p-switch doors. $00EBDE: The Map16 tile of a door which can be entered from any position if touched (used for the large castle door). $00EBE5: The tileset where the castle door is enterable. $00EBE9: The Map16 tile number for the normal door (independent of power up and p-switch). $00EBED: The Map16 tile number for the small door (enterable when not big, independent of p-switch). $00EBF6: The Map16 tile number for the p-switch door (independent of power up, p-switch must be active). $00EBFA: The Map16 tile number for the small p-switch door (enterable when not big, p-switch must be active). $00EBFD: Code that checks Mario's powerup state when entering doors. Change to [80 02] (BRA $02) to allow small doors can be entered even if Mario is big, and normal doors to be entered even if riding Yoshi. $00EC01: Checks whether Mario is centered enough to enter a non-boss door. Replace it with [$80,$03] to disable this behaviour. $00EC09: Replace it with [$00] to allow doors to be enterable in the air. $00EC10: Sound effect to play. $00EC11 (8-bit) is the SFX ID and $00EC13 (16-bit) is the SFX port. See $7E1DF9 to $7E1DFC for more details Note: All the Map16 tiles must be located on page 0.
$00EC0B	1 byte	Controller	Change from 16 to 15 to allow Mario to enter doors by holding up, instead of just pressing it.

$00EE69	2 bytes	ASM	Change to EA EA (NOP #2) if you want Small Mario to be able to break turn blocks with a spin jump. Alternatively, change this address to 80 18 (BRA $18) if you want turn blocks to not be breakable by spin jumps.
$00EE79	1 byte	Objects	Controls which (page 1) tile activates the brown creating/eating block sprite when stood on. Note that a few tiles are handled before this and can not trigger this effect.
$00EEB2	1 byte	Objects	Change from 1E to 04 (BNE jumps to `$00EEB7` instead of `$00EED1`) to make it possible to trigger already triggered switch palace switches, as opposed to them randomly becoming solid for no obvious reason. Note that this only applies to switches inserted using Direct Map16; switches inserted as extended objects will still disappear.
$00EEF6	1 byte	Mario physics	Change this to [80] to disable sliding on slopes. The slide will instead be changed to ducking like on flat terrain
$00EEF8	3 bytes	ASM	Change to [EA A9 00] to enable sliding while holding an item.
$00EF01	1 byte	Mario tilemap	[1C] Mario sliding pose.
$00F05C	36 bytes	Misc.	Table for several Map16 blocks that handles which bounce block sprite is shown when the block is hit. Please see this thread and this thread for additional information.

$00F120	217 bytes	Mario physics	Shared Map16 page 1 interaction routine. This handles Munchers, spikes and bounce blocks (including but not limited to Note Blocks and ?-blocks). This routine is called for most of Mario's interaction points as well as carryable sprites and the cape. The order in which the routine goes as follows: Check for Yoshi Handle hurt blocks Hande bounce blocks The routine can be jumped at various points: $00F120 includes the Yoshi check and is used if the player is above a block. $00F127 handles hurt blocks regardless whether the player rides Yoshi or not and is used for the other sides of a block. $00F160 handles only bounce sprites and is used for the invisible blocks and sprite interaction. All these routines take the following inputs: A: Map16 tile which is interacted Y: Block direction (follows a similar fomat as $7E0077).	Additional Data
$00F160	263 bytes	Subroutine (JSL)	Routine used to trigger SMW blocks, used for example by kicked sprites to make ON/OFF blocks, Note blocks, etc. activate when hitting them.

$00F2BB	3 bytes	ASM	Change [99 3C 1F] to [EA EA EA] to make the 1up checkpoint work again when reentering a level
$00F2C0	183 bytes	Mario physics	Shared Map16 interaction routine to handle interaction with various tiles on page 0. The tile number is passed in Y, and the specific interaction point being processed is identified via a value passed in A, using a format similar to that of $74. The routine specifically handles interaction for the following tiles, in the following order: Liquids (000-005) Midpoints (038) Climbable blocks (006-01C) Moons (tile 06E) Yoshi coins (tiles 02D, 02E) Normal coins (tiles 02A-02C) The game uses multiple entry points to the routine depending on the interaction point being processed: $00F2C0: MarioBody. This specifically sets A to #$01. $00F2C2: MarioAbove and MarioBelow. $00F2C9: MarioSide and MarioHead. This skips liquid interaction. $00F309: TopCorner and WallFeet. This skips liquid, midpoint, and climbable block interaction.	Additional Data
$00F2CD	33 bytes	Objects	The code for the midway point tile (Map16 tile 38, not the extended object). - $00F2CE: what tile gets generated after breaking the midway point tape (see $9C; default is 02 - none). - $00F2D5: change to [80 01] to disable the glitter that appears after touching a midpoint. - $00F2E2: change to [80] to disable midway powerups (or [80 01] to make them always make you big, even if you have a better powerup). - $00F2E5: what powerup midway points give you. - $00F2E9: what sound effect midway points play.

Note that this will also stop them from respawning when you've got five of them. - $00F34A: number of Yoshi coins that need to be collected to trigger the "collected all" flag. - $00F354: changing [99 2F 1F] to [EA EA EA] will make the Yoshi coins reappear even after collecting all 5 (or more) of them. - $00F359: Yoshi coin sound. - $00F35E: amount of regular coins a Dragon Coin gives you. - $00F364: value stored to $9C when the coin is collected.
$00F377	59 bytes	Subroutine (JSL)	The subroutine that handles the score when you get a Yoshi coin. Changing $00F37A [EE 20 14] to [EA EA EA] will stop the Yoshi Coin counter from increasing and giving you points and giving you a life after you collected enough for one.
$00F38A	40 bytes	Subroutine (JSL)	Subroutine to spawn a score sprite at Mario's position. Load the score sprite to spawn in A before calling; alternatively, jump a few bytes earlier to $00F388 to specifically spawn a 1up score sprite.
$00F3B2	18 bytes	Subroutine (JSR)	This subroutine gets an index to the "one bit per level" tables ($1F2F, $1F3C, $1FEE) depending on the overworld level number ($13BF). When it returns, Y holds the byte index to $1F2F and A holds the bit to check/set.
$00F3E3	1 byte	Coordinate	[0A] Signed offset of the enterable region of the left tile of an exit-enabled vertical pipe from the left edge of the tile, in pixels, minus 1 Change to #$FF to make up pipes enterable as no matter where you hit them. (For use with the hex edit at $00F3F9)

$00F3ED	1 byte	Misc.	[37] Offset of entering vertical pipes. Setting it to any other number than 36-38 will make the player incapable of entering.
$00F3F9	1 byte	Coordinate	[05] Width of the enterable region of a vertical exit-enabled pipe tile (either one), in pixels In vanilla SMW, this is half the width of the enterable region of the entire pipe, but this won't be true if the two exit-enabled pipe tiles are made to have overlapping enterable regions. Change to #$10 to make up pipes enterable no matter where you hit them. (For use with the hex edit at $00F3E3)
$00F43A	1 byte	Sound effect	Going Down Pipe Sound
$00F443	10 bytes	Subroutine (JSR)	Subroutine that checks if Mario is in the center of a door. Not used for boss doors. $00F44B [08] is the width of the enterable region of the door (up to 0x10). $00F447 [04] is how far to offset the enterable region; this should be set to half of $00F44B.
$00F44D	24 bytes	Mario physics	Routine that sets up Mario's object collision points for RAM addresses $98-$9B, inclusive.
$00F545	80 bytes	Subroutine (JSL)	Routine that handles behaviours for various Map16 tiles. For P-Switch dependent tiles, this routine only sets the "act as", not the graphics. $00F54C: Map16 tile number (low byte) that should act like a ? Coin Block when the blue P-Switch is active. Default is ($00)29, the Invisible POW ? Coin Block. $00F555: Map16 tile number (low byte) that the Invisible POW ? Coin Block should act like when the blue P-Switch is active. Default is ($01)24, the ? Coin Block. $00F55B: Map16 tile number (low byte) that should act like a Brown "used" Block when the blue P-Switch is active.

If the result is less than #$10, the value gets incremented by 1 and stored to $1423. This makes it so that only tiles ($00)EC to ($00)FB, the Palace Switch tiles, set $1423. $00F57B: Map16 tile number (low byte) that should act like a Coin when the blue P-Switch is active. Default is ($01)32, the Brown "used" Block. $00F585: Map16 tile number (low byte) that should act like a Coin when the silver P-Switch is active.

$00F598	2 bytes	Mario physics	Highest Y position that the player is able to be at, 16 bit. Note that this is a negative value.
$00F5AD	2 bytes	Misc.	Change to 80 03 (BRA $03) to make it so falling into a pit results in death even in Yoshi wings levels, or to 80 00 (BRA $00) to make it so falling into a pit will always activate the normal exit.
$00F5B7	79 bytes	Subroutine (JSL)	Hurt Subroutine (JSL to it to hurt the player). $00:F5B9: Change to F0 to make mario invincible. (Will not make him invincible to crushing objects, lava or pitfalls). $00:F5C1-$00:F5C3: Change from 0D 93 14 to EA EA EA to make Mario die normally when touching an enemy/muncher even after getting the goal tape/sphere. $00:F5C6: Change from 9C E3 18 to EA EA EA to prevent coin game cloud counter from resetting on hit. $00:F5D7: Change this to 80 to have Mario die when touched, regardless of powerup status. $00:F5E3: This SFX plays when you get hit when flying. $00:F5ED: Invincibility timer when hit while flying. $00:F5F4: Mario shrinking SFX. $00:F5F8-$00:F5FB: Set to EA EA EA EA to disable item box auto-falling when you get hurt. $00:F5FC-$00:F5FF: Change the "A9 01 85 71" to "EA EA EA EA" to disable mario's shrinking animation when hit.
$00F606	35 bytes	Subroutine (JSL)	Death Subroutine (JSL to it to kill Mario). $00F607 controls the speed at which the player jumps up ($7E007D format). $00F60B controls which music is played when Mario dies. $00F619 can be changed from 0D 14 to 12 14 to make the screen not scroll when the player loses a life. $00F61C controls the amount of time Mario stays on screen before dying. *note that if Mario Falls into a hole, the rom will JSL to $00F60A to skip the death animation
$00F69F	4 bytes	Misc.	Where Mario has to be vertically on-screen for the game to consider the screen "caught up" with him in a particular direction, thereby stopping it from scrolling. The first two bytes are for scrolling upwards, while the second two are scrolling down.
$00F6A7	6 bytes	Misc.	How fast the camera "catches up" to Mario when scrolling vertically. The first two bytes are when scrolling upwards, while the second two are scrolling down. The third entry is a bit strange, and for the most part unused. If the level is set to "no vertical scroll unless flying/climbing/etc.", then it gets used as the upwards scroll speed of the screen when it's below the point where the screen "locks" vertical scrolling. Since this is normally at the bottom of a level where the screen can't scroll any further down, it can only really get used in vertical levels.
$00F6AD	6 bytes	Misc.	Vertical limits for scrolling the screen. The first two bytes are the highest distance the screen can scroll upwards; essentially, it's the top of the level. The second two are the highest distance the screen can scroll upwards... when the screen is stationary or moving downwards. Recommended to keep it identical to the first two bytes. The third entry is where the screen's vertical scrolling locks in a level with the "no vertical scroll unless flying/climbing/etc." option. The screen can actually still scroll vertically if it goes below this point, but it can't scroll up past it unless one of the special conditions is met.
$00F6B3	4 bytes	Misc.	16-bit values for the maximum X position the game should move the static camera region towards when the screen is scrolling in the direction Mario is facing. They're used to position the camera slightly in front of where Mario is running. The first is for moving left, the second is for moving right.
$00F6C1	4 bytes	Misc.	Two 16-bit values for the X speed of the screen when scrolling with L/R. The first value is used when scrolling right with R, while the second is used when scrolling left with L. These values are also slightly reused for a positive/negative check when the screen is just normally scrolling horizontally as Mario moves around. If you want to change that so that you can freely modify the signage of these two values, you can do so by changing $00F8CB from 0xBF to 0xC5.
$00F6C7	4 bytes	Misc.	How quickly the screen scrolls horizontally when "catching up" to Mario while he's walking around normally. The first two bytes are right, while the second are left.
$00F6CD	4 bytes	Misc.	16-bit values for the maximum X positions the game should move the static camera region towards when scrolling the screen with L or R. The first is for scrolling right with R, the second is for scrolling left with L.
$00F6DB	516 bytes	Misc.	Level camera handling routine. This routine handles camera movement with the player. $00F713 - Horizontal scroll handler in horizontal levels. $00F766 - Horizontal scroll handler in vertical levels. $00F7F4 - Vertical scroll handler, for both horizontal and vertical levels. $00F8AB - Subroutine to handle scrolling the screen in the direction the player is moving, for shifting the screen slightly ahead. $00F79D - Handler for scrolling Layer 2 (mainly background), which determines the scrolling rate in relation with layer 1.
$00F6E5	2 bytes	Misc.	Distance Mario must be offset to the left of the screen's "hotspot" defined by $7E142A for the screen to scroll leftwards.
$00F6EC	2 bytes	Misc.	Distance Mario must be offset to the right of the offset at $00F6E5 for the screen to scroll rightwards. Essentially, this defines the width of the area where the screen will never scroll horizontally.
$00F70E	2 bytes	Coordinate	Lowest Y position the screen is allowed to scroll down to in horizontal levels. Change from C0 00 to CF 00 (do the same on $00F6B1 so the "no vertical scroll unless flying/climbing/etc." work consistently) to allow the bottom row of 16x16 blocks to be shown.
$00F727	1 byte	Misc.	Change #$00 to #$02 (value to be stored in $7E:0055 and $7E:0056) and you'll get a SMB1-like effect regarding screen-scrolling: it's impossible to go to the left, even with L/R-scrolling.
$00F79D	13 bytes	ASM	Code that handles the Layer 2 horizontal scroll settings (LM's "Layer 2 (BG) Scrolling Rate").
$00F7AA	24 bytes	ASM	Code that handles the Layer 2 vertical scroll settings (LM's "Layer 2 (BG) Scrolling Rate").
$00F806	2 bytes	Coordinate	When vertical scrolling is enabled and not locked at the bottom of the level, this is the onscreen Y position at which the screen should try to keep Mario centered. If Mario is above this line, the game will try to scroll the screen up, and if below, the game will try to scroll down.
$00F878	1 byte	Misc.	Change from D0 to 80 to activate free vertical scrolling. This will bypass the routine that checks whether Mario is standing on solid ground or not (RAM address $72) and sets the scrolling flag accordingly. The camera follows Mario instead of waiting for him to land on something.
$00F99C	2 bytes	Coordinate	What 16-bit Y position on screen ($7E:0080) the player should have at the very minimum, before being killed in the Iggy/Larry battle room. Used to simulate lava tiles.
$00F9F5	27 bytes	Empty	Unused data.
$00FA10	9 bytes	Subroutine (JSL)	Unreachable, but can be JSL'ed to clear out the sprite status table.
$00FA19	44 bytes	Sprite subroutine (JSL)	Load slope information. This is a subroutine which gets the slope information for the current tile which means slope type and height of the ground for the current X position. It's used to load the slope info for sprites. Input: Map16 tile ID low byte $0A: X position of the interaction point $0C: Y position of the interaction point Output: Y: Index to the ground height table, calculated with from $08 * 4 + $0A & #$0F. $00: Y position of the current interaction within the block, calculated from $0C & #$0F. $05-$07: 24-bit pointer to the ground height table $00E632. $08: Slope type.
$00FA46	1 byte	Misc.	Time to shake ground when you hit the big switch in the switch palace. Default is 20.
$00FA4D	1 byte	Sprite number	Sprite that's spawned when hitting a switch palace. Note that it always uses slot 02.
$00FA80	95 bytes	Subroutine (JSL)	The routine which triggers the goal tape. $00FABF - [06] The state which sprites are put into when the goal tape is triggered. Can be set to any of the valid values for RAM address $14C8.
$00FADF	28 bytes	Misc.	Table of the various sprites Mario receives for carrying different items past the goal tape. The table itself is divided into four 7-byte sections: P-switches and springboards will use the second section, keys will use the third, baby Yoshi will use the fourth, and anything else will use the first. Each section is then indexed by Mario's current state, in the order: small, big, cape, fire, with star power, on Yoshi, and unused. The star power index is essentially unused, however, because the counter always gets cleared before the table gets loaded from. If the value returned is E0-EF, Mario will receive the sprite written at $00FB50 (1-up by default). If it's F0-FF, he'll receive the sprite at $00FB54 (...also a 1-up by default). In both cases, it'll also store the lower four bits to $1594, which for a 1up, will affect the number of lives it gives (0 = 1 life, 1 = 2 lives, 2 = 3 lives, 3 = 5 lives). It's 0 in every obtainable case, though, so the feature is effectively unused. Additionally, $00FB40 is the sprite to spawn if Mario already has the sprite in his item box (again, 1-up by default). Lastly, you can re-enable factoring star power into the table by changing $01C0FE to EA EA EA.
$00FB40	1 byte	Sprite number	Sprite that the Blue/Silver P-switch, Portable Spring Board, Throw Block Sprite and carryable stunned enemies will turn into when they reach the goal point.
$00FB50	1 byte	Sprite number	Sprite that the Key will turn into when it reaches the goal point.
$00FB53	5 bytes	ASM	Change to EA EA EA EA EA to prevent the 1UPs being spawned at the goal point. $00:FB54 controls the sprite number that Baby Yoshi (Green, Red, Yellow, Blue) will turn into when it reaches the goal point.
$00FB6F	1 byte	Sprite Misc.	The Y speed of the sprite when you carry an item over the goal.
$00FB74	1 byte	Sprite Misc.	The X speed of the sprite when you carry an item over the goal.

$00FBAC	8 bytes	Sprite subroutine (JSL)	Routine that handles sprites turned into a coin by the goal tape. It's a JSL wrapper to the subroutine at $00FBB4.
$00FBB4	111 bytes	Sprite subroutine (JSR)	Routine that handles sprites turned into a coin by the goal tape. It first makes the coin appear as a smoke cloud until $1540,x is 0, then it draws the coin, handles its movement and finally it gives Mario a coin, erasing the sprite permanently.
$00FC17	1 byte	Misc.	[02] Difference between point values of successive sprite coins spawned at the goal tape. The default is 02, so the point sequence will go 100, 400, 1000, 4000, etc.; you can change it to 01 to make the point values go 100, 200, 400, 800, etc. or to 00 to make it always stay at 100 no matter how many sprites get turned into coins.
$00FC23	87 bytes	Sprite subroutine (JSL)	An unused routine. When called, if there's a Yoshi spawned in the level and Mario is not riding him, it'll teleport him to the left edge of the screen running towards the right, and move him to Mario's Y position. If there's no Yoshi spawned, nothing happens. No matter what, the Yoshi will be turned to green and without wings. Note that the routine overwrites the Y register. $00F6CE: [$10] X speed given to Yoshi.
$00FC7A	114 bytes	Subroutine (JSL)	Used in SMW to initialize Yoshi when entering a level, or sublevel. JSLing to this will cause a Yoshi to spawn and Mario will be riding him, however the Yoshi will not transfer to sublevel or to the overworld. You must set $13C7 if you plan to manually JSL to this routine. Changing $00FCCE to 0x80 will keep Yoshi from turning blue after grabbing a pair of Yoshi wings.
$00FCF6	1 byte	Coordinate	X lo position of Iggy and Larry at the start of the boss battle.
$00FCFA	1 byte	Coordinate	X hi position of Iggy and Larry at the start of the boss battle.

Hence, if Layer 1 and Layer 2 are offset from each other, this value will differ between the two, even when the sprite is at the same position with respect to the level. $0F (1 byte): Index of one of the 4 collision points currently in use. Also used to eject sprite out of block horizontally: #$00 = SpriteH: Right (touches blocks from left) #$01 = SpriteH: Left (touches blocks from right) #$02 = SpriteV: Down (touches blocks from above) #$03 = SpriteV: Up (touches blocks from below) Be careful when using custom blocks, $0F remains used before and after custom block processing at $019533.

Any other sprite will branch to $019FE0 $019FA7 change to EA EA EA EA EA to the P-Balloon last forever. $019FB0 is the time at which the deflatting animation starts. (default 30) $019FC2 change 90 to 80 to make Mario keep the balloon effect even after taking hits or power-ups. (causes weird behaviour when dying)

$01A295	2 bytes	Sprite Misc.	Change to [$80,$1E] to make Baby Yoshi instantly grow when eating something, regardless if it's a powerup or not. Change to [$80,$5D] to make Baby Yoshi never grow instantly when eating something, even if it's a powerup. It will count as one sprite eaten instead. If changing this, you also need to apply the hex edit at $03C03C for it to work properly.
$01A2BC	1 byte	Sprite number	Sprite that Baby Yoshi turns into
$01A2C6	1 byte	Sound effect	Yoshi's egg explodes sound
$01A2FB	1 byte	Misc.	Number of enemies Baby Yoshi must eat to grow
$01A300	2 bytes	Sprite Misc.	Change to $80,$02 to disable getting a coin when Baby Yoshi eats something.
$01A3DF	44 bytes	Sprite subroutine (JSR)	Routine called by the shared sprite GFX routines at $019D5F and $0190B2 to hide tiles that would be drawn offscreen vertically. It works for both 1 and 2 tile high sprites by using the first two bits in $186C to determine which tile(s) should be hidden.
$01A40D	956 bytes	Sprite subroutine (JSR)	The primary routine used to process most standard interactions between a sprite and other sprites; call this routine from within the sprite's MAIN routine to do so. A JSL to this routine can be found at $018032. When two sprites are interacting, only the sprite in the higher slot actually processes it to prevent the interaction from being handled twice. Interactions can be prevented entirely by setting either sprite's "don't interact with other sprites" tweaker bit ($1686) or $1564. Notably, not using one of these two methods and instead simply not calling the routine in the first place does not guarantee interaction will not be processed, as it can still occur if the handling is coming from a sprite in a higher slot. An example of this in the original game exists with shells and Thwomps, who are immune to thrown shells when they handle the interaction, but are killed when the shell does instead. Overwrites $00-$03 when called. When processing interaction for sprites in status 8 that have the "change direction when touched" tweaker bit set ($1686), $157C is assumed to be their horizontal direction and $15AC will be set for a timer intended to control a turning-around animation for the sprite.
$01A61E	7 bytes	Sound effect	Sound effects to use for consecutive bounces on enemies. Begins with [13] (1st bounce) and ends with [19] (7th bounce).

$01A7DA	1 byte	Sprite number	Sprite spawned from Para-Goomba
$01A7DB	1 byte	Sprite number	Sprite spawned from Para-Bomb
$01A7DC	93 bytes	Sprite subroutine (JSL)	Subroutine that handles interaction between Mario and the sprite slot currently in X. If the "Don't use default interaction with player" tweaker bit in $167A,x is not set, the routine checks for contact between Mario and the sprite and handles the default interaction by jumping to the routine at $01A83B. Otherwise, it just checks for contact and returns with carry set if there's contact, and clear if there's not contact (note that when the sprite uses default interaction, the return carry isn't meaningful). Note that the routine will return "No contact" and skip interaction every other frame if the "Process interaction with player every frame" tweaker bit in $167A,x is not set, or if the sprite is horizontally offscreen during a frame in which it should be interacted with.
$01A7F0	3 bytes	Sprite Misc.	Change from [1D A0 15] to [EA EA EA] to fix a glitch where sprites lose their interaction with the player while touching the edge of the screen. An example of this happens when a Banzai Bill's leftmost pixel goes past the left edge of the screen.
$01A83B	779 bytes	Sprite subroutine (JSR)	Default sprite interaction routine. The sprite interaction routine calls it if $167A,x is positive/ bit 7 is not set. - $01A852 controls number where the star chain should stop. To be used with $01A856 - $01A856 controls, how many points/ one-ups are added if the max limit of a star chain is reached. To be used with $01A852 $01A8D0 handles the code when you jump on a spiky enemy. Change $01A8D3 to $AD (LDA $xxxx) to disable spin jumping on spiky enemies. On contrary, change $01A8D3 to $80,$01 (BRA $01) to disable jumping with Yoshi on spiky enemies. To disable both, change $01A8D0 to $80,$04 (BRA $04). $01A91C handles the code when you jump on a non-spiky enemy. Change $01A91F to $AD (LDA $xxxx) to make spin jumps count as normal jumps. On contrary, change $01A91F to $80,$01 (BRA $01) to make jumps with Yoshi on enemies count as regular jumps. To make both count as regular jumps, change $01A91C to $80,$04 (BRA $04). Change $01A930 to $00 to enable the boost gain with spin jump kill. $01A940 is the sound effect to play when you kill an enemy with a spin jump/ jump with Yoshi. $01AA42 is the routine for carryable sprites. Change $01AA61 to $AD (LDA $xxxx) to enable carrying more than one sprite at time even though you already have one.

The rate of movement is “subpixels” (1/16th of a pixel) per frame, similarly to Mario's speed handler at $00DC4F. Best call these JSL subroutines instead, since this use JSR-RTS: $01801A: Y speed, no gravity and no object interaction $018022: X speed, no gravity and no object interaction $01802A: X and Y speed, with gravity and with object interaction $01ABCC-$01ABD7: Calls $01ABD8 with the current sprite X index +12 (number of existing sprite slots) to use the X position instead of Y. $01ABD8: The position updater itself.

$02881E	5 bytes	Sound effect	Code for one of two sound effects played when the ON/OFF switch block is hit (the other being at $02918C). This one plays first, when the block is actually hit. It also prevents the normal "hit block" sound from playing. To disable this one (thereby restoring the normal block-hit sound effect), change the first two bytes here to [80 03].
$02887D	36 bytes	Subroutine (JSL)	Seems to be a subroutine for spawning stuff from blocks. What is spawned depends on the value of $05: 00 - nothing 01 - mushroom 02 - flower 03 - star 04 - cape 05 - 1-Up 06 - coin 07 - coin (sets multiple-coin-block timer) 08 - growing vine 09 - nothing? 0A - P-switch (blue/gray depending on block X position) 0B - key/wings/balloon/shell (depending on block X position) 0C - green Yoshi egg 0D - green Koopa shell (with stun timer set) 0E - changing item 0F - directional coins 10 - key (but a random blue shell-less Koopa also pops out) 11-FF - completely glitchy; best not to use This subroutine can be used properly in a block, but the data bank must be 02 and the lower nybbles of $98 and $9A must be cleared. All values except 06 and 07 JSR to the main "spawn sprite from block" routine at $0288DC; values 06 and 07 JSR to the coin-spawning routine at $028A66. Note: When used in a custom block under sprite interaction, make sure you preserve $1695 and then restore it after this routine to prevent a random splash sprite from spawning.

$0288D6	3 bytes	Sprite number	Sprites spawned by key/wings/balloon/shell block, indexed by its X position. Note that this table is only 3 bytes long, not 4 bytes; the shell actually comes from the key's sprite status.
$0288D9	3 bytes	Sprite Misc.	Sprite status of sprite spawned by the key/wings/balloon/shell block, indexed by its X position. Note that this table is only 3 bytes long, not 4 bytes; the shell is given an invalid sprite status.
$028905	98 bytes	Subroutine (JSL)	The subroutine that generates a sprite from a block (tile 120 or 125, for example). $02895F - Change from F0 to 80 to allow Directional Coins to reappear if you activate the block, then leave the area and come back.

$028A03	4 bytes	ASM	If you change [F6 C2 F6 C2] to [EA EA EA EA], then tile 125 will spawn a flying red coin instead of Yoshi wings on X-coordinate (X&3 = $01).
$028A08	2 bytes	ASM	[A9 FF] Change to [80 03] or [A9 00] to prevent the stun timer of the shell spawned from blocks 127 and 128 from ever being set. It will just spawn as a plain shell rather than a shell that will "wake up". (Or you can change the second byte to a different value to make the stun timer shorter.)
$028A42	2 bytes	Sprite tilemap related	Colours of P-Switches (Blue, Silver) when spawned by tile 11D
$028A44	34 bytes	Subroutine (JSL)	Subroutine for generating smoke when hitting a block. You can use this in a custom block, but be sure to set up $98 and $9A accordingly.
$028A66	67 bytes	Subroutine (JSR)	Subroutine for spawning the coin that comes out of a ? block (for example tile 124). It can be used in a custom block, but the low nybbles of $98 and $9A must be cleared first. This subroutine ends with RTS, but it may be accessed with a JSL to $02889D.
$028AB1	182 bytes	Subroutine (JSL)	1up handler routine. $02:8AC9 is the number of frames to wait before awarding each extra life after the first, when a 2up or higher is obtained. (Note that reducing this may skip some of the 1up sound effects.) $02:8ACE is the sound effect.

$02917E	1 byte	Sound effect	Sound Effect from bouncing on a Note Block
$02918C	5 bytes	Sound effect	Code for one of two sound effects played when the ON/OFF switch block is hit (the other being at $02881E). This one plays second, once the bounce sprite for the switch finishes its animation. To disable this one, change the first two bytes here to [80 03].
$0291B5	1 byte	Misc.	Value for $9C to change what Map16 tile is created when a multiple-coin-block is hit after its timer has run out.

Note that changing this will only affect the tile that appears before the block starts spinning.
$029265	241 bytes	Subroutine (JSR)	INIT routine for most bounce sprites. Mainly used to allow bounce sprites to collect a coin directly above them, though the feature is unfinished and the coin's replacement tile ends up being a solid block instead of empty. Changing $0290ED to [AD] will disable this. $029330 identifies which block on page 0 can be collected this way. Keep in mind that this is independent of the acts like setting and therefore support for other tiles has to be implemented manually.
$029356	60 bytes	Subroutine (JSR)	Code that creates a spinning coin sprite from a bounce sprite spawned by tile 2B. However, this never happens (tile 2B doesn't spawn a bounce sprite), so this subroutine seems to be unused. It is called at $02934A.
$029444	1 byte	Misc.	If you change this from FF to 00 then you won't see the eyes blinking or the shell shake. However, do keep in mind that it will affect the Bob-ombs too. If you hit them with a cape or a block from underneath it won't explode.
$029456	1 byte	Misc.	Score added for hitting an enemy from below or smacking an enemy with the cape 00 = Nothing at all 01 - 07 = Scores 200-8000. 08 = 1UP. 09 = 2UP. 0A = 3UP. 0B = 5UP (glitched). 0C-FB = Best not to use. FC-FF = Scores 10-80

$029663	51 bytes	Sprite subroutine (JSR)	Routine that gets sprite clipping value for quake sprites (i.e. bounce sprites and Yoshi's stomp). Takes the place of "sprite clipping B" from the standard routines.
$029696	34 bytes	Subroutine (JSR)	Get the cape hitbox for clipping B. $02969B [$02]: Hitbox horizontal displacement (low byte). $0296A2 [$00]: Hitbox horizontal displacement (high byte). $0296A5 [$14]: Hitbox width. $0296B4 [$10]: Hitbox height. Note that there is no vertical displacement for the cape hitbox.
$0296B8	4 bytes	Sprite Misc.	OAM indexes for the smoke images (in the $0200 block).
$0296CB	12 bytes	Pointer	Pointer to the smoke images. ($7E:17F0 - $7E:17FB)
$0297B3	1 byte	Sprite Misc.	[$F0] OAM index (in $0200) used by the sprite contact graphics (when not in Reznor/Morton/Roy's room). Since this sprite draws 4 tiles, it overlaps with Mario's fireballs (which use slots $F8 and $FC), causing it to be partially cutoff whenever there's some fireballs (it's easy to see if you spinjump on a spiky enemy while being fireflower Mario). To fix it, change this to $E8.
$029922	5 bytes	Sprite tilemap related	Mario/Luigi's trail of smoke tilemap. It uses palette 8.
$0299E9	4 bytes	Sprite Misc.	OAM indexes for the spinning coins that come out of ? blocks. The next index after each of these is also used (the GFX routine will store to $0200,y and sometimes to $0204,y as well).
$0299F1	183 bytes	Sprite subroutine (JSR)	Main handling routine for the spinning coins that come out of ? blocks. $029A4F is a fourth of the rolling coin tilemap. This tile is 16x16. $029A54 is the properties of the rolling coin flying from question blocks. $029A6B controls the frames, changing to [D0 00] or [EA EA] will cause all 4 frames to only use 1 16x16 tile. Have to combine with $029A4F and $029A6E (same tile) for the complete effect. $029A6E is three fourths of the tilemap of the rolling coin. These tiles are 8x8, but they're duplicated and placed above each other, making it 8x16.
$0299FD	1 byte	Sprite physics	Downwards Y acceleration for the coin sprites spawned from coin blocks. Decrease this value to make them fly higher.
$029AAD	1 byte	Misc.	How many points you receive for getting a coin out of a block.

$029FD4	1 byte	Sprite physics	Initial Fireball Y Speed #2
$029FDB	1 byte	ASM	Change to 80 to make the player's fireballs go through objects.
$029FE4	1 byte	Timer	Fireball hit timer. This increases each time a fireball hits an object or a sprite. Changing it to #$01 will fix the bug with straight fireballs where the second fireball will go through objects if the first one is hitting an object. Use in conjunction with the bounce speed table at $029F99.
$02A046	1 byte	Sound effect	Sound effect played when the players fireball touches an object. It is #$01 by default, and the sound effect is in bank $1DF9.
$02A0B9	1 byte	Sprite Misc.	Change from #$09 to #$0B (or #$15 in a SA-1 ROM) to fix a glitch with both the player's and Yoshi's fireballs where they don't interact with sprite slots above 9.

Note that this will also make the sprite's hitbox a bit more forgiving (less likely to hurt Mario). Also be aware that it's still possible to clip into a Mega Mole if Mario has upwards speed, due to the code at $0387E6 (it's required to allow Mario to jump off of the Mega Mole).

To do that, have both hitbox A and B stored in scratch RAM $00-$0B, then call `JSL $03B72B` to check.	Clipping data
$03B69F	70 bytes	Sprite subroutine (JSL)	"Get sprite clipping A" subroutine. Stores the clipping X position low byte to $04, the clipping X position high byte to $0A, the clipping width to $06, the clipping Y position low byte to $05, the clipping Y position high byte to $0B, and the clipping height to $07.

$03B72B	49 bytes	Sprite subroutine (JSL)	“Check for contact” collision subroutine. Uses the values in scratch RAM set by $03B69F and either $03B6E5 or $03B664 (or occasionally custom values) to determine whether two sprites, or a sprite and the player, are in contact. If the carry flag is set after calling this, they are in contact. It functions using the axis-aligned bounding box (AABB), it first checks if they are #$80 pixels apart, if they are, then the subroutine ends with carry clear, otherwise it then checks the total distance of their widths or height against their difference of their XY position, and if within range, carry is set. Note: The XY position is the top left boundary of the box, and as the width and height increases, the box extends rightwards and downwards.	Input values and destroyed values Better, sorted format

Not used if LM's overworld level expansion hijack is applied. $03BC7F: Table containing 2 bytes for each of the 8 rows of the message box's text, as the first two bytes of the line's stripe header. Note that this table may be moved slightly earlier to $03BC79 instead if LM's overworld level expansion hijack is applied. $03BE80: Table of 16-bit offsets to each individual message's data, indexed by ($13BF * 2 + ($1426 - 1)) * 2. If LM's overworld level expansion hijack is applied, this table is instead moved to read3($03BBD9) and changed to instead use direct 24-bit pointers to each message's data (using the same indexing system, except 3 instead of 2). This space is then instead used for the initial level flags (moved from $05DDA0). $03BCC0: Table of four 24-bit pointers to the locations of ExGFX60-63 (uncompressed) in the ROM. If a file is not inserted, the pointer is 000000. $03BCDC: JSL routine added in LM v3.00+ to compute the screen number that Mario is on, returned in X. Note that this routine does not preserve Y. $03BCE0: Used by LM as a routine to implement the additional secondary entrance bytes.

$03CC14	36 bytes	Sprite subroutine (JSR)	Subroutine for the Lemmy Koopa and Wendy O. Koopa boss fights. Jumps to a graphics subroutine, then if the sprite is dead or the lock sprites flag is set, returns. Otherwise, loads the current fight phase from table $151C, then executes the pointer subroutine.
$03CC29	14 bytes	Pointer	Pointers to the various phase routines of the Lemmy Koopa and Wendy O. Koopa boss fights. [8A CC] Phase 0: In pipe [21 CD] Phase 1: Rising [C7 CD] Phase 2: Out of pipe [EF CD] Phase 3: Descending [0E CE] Phase 4: Hit [5A CE] Phase 5: Falling [89 CE] Phase 6: Sinking in lava
$03CC38	7 bytes	Sprite Misc.	Possible X positions for Lemmy/Wendy and their decoys.
$03CC40	7 bytes	Sprite Misc.	Possible Y positions for Lemmy and his decoys.

$03CC50	1 byte	Sprite Misc.	Number of frames that Wendy/Lemmy's dummies take to rise out of their pipes.
$03CC5A	48 bytes	Sprite Misc.	Indexes to $03CC38 / $03CC40 to choose from for each RNG value (00-0F). The first set of 16 bytes is used for Wendy/Lemmy, the second set is the corresponding value for the first dummy, and the third set is the corresponding value for the second dummy.
$03CC8A	86 bytes	Sprite subroutine (JSR)	Subroutine that runs for Lemmy Koopa and Wendy O. Koopa's "in pipe" phase. This routine handles several of the Lemmy/Wendy fight behaviours: - Calls the RNG routine to determine at what X positions (pipes) Lemmy/Wendy and their dummies appear out of. - Sets their Y positions depending on the pipe they appear from. Always #$50 if the boss is Wendy, otherwise, loads Y positions from a table corresponding to the heights of Lemmy's pipes. - Jumps to the routines that initialize the sprite tables. - Calls the RNG routine to determine Lemmy/Wendy's emerged animation pointer, and animation frame when coming out of a pipe. - Sets the phase timer for Lemmy/Wendy's next phase. Timer value depends on their current animation. - Increments the current phase table.
$03CCB7	1 byte	Sprite Misc.	Initial Y position of Wendy and her decoys.
$03CD21	22 bytes	Sprite subroutine (JSR)	Subroutine that runs for Lemmy Koopa and Wendy O. Koopa's "rising" phase. Updates Lemmy/Wendy's Y speed and position when rising out of pipes. When the phase timer for this phase reaches 0, the routine sets the phase timer for the next phase, and increments the current phase table.
$03CD27	1 byte	Timer	Amount of time Lemmy/Wendy remain vulnerable before retreating into their pipes. However, their animations will become glitched if this is set higher than its initial value of 0x40.
$03CD37	144 bytes	Sprite Misc.	Animation frame data for Lemmy Koopa and Wendy O. Koopa when out of a pipe. Indexed by a combination of the emerged animation pointer and the current phase timer.
$03CDC7	19 bytes	Subroutine (JSR)	Subroutine that runs for Lemmy Koopa and Wendy O. Koopa's "out of pipe" phase. Jumps to a subroutine that checks if Mario has jumped on Lemmy/Wendy/dummy. If he hasn't, the routine checks if the current phase timer is 0. If it is, the the routine sets the phase timer for the next phase and increments the current phase table. If the phase timer is not 0, the routine jumps to a subroutine that handles Lemmy/Wendy's animations.
$03CDD5	1 byte	Misc.	Setting for Lemmy/Wendy's decoys. 00 - keep appearing after boss's defeat, 01 - interaction disabled, 02 - paralyzed, 03 - normal
$03CDDA	21 bytes	Sprite subroutine (JSR)	Subroutine that handles Lemmy Koopa and Wendy O. Koopa's animations when out of a pipe. The accumulator contains the current phase timer when the routine is called, and is right‐shifted twice then stored to $00. The emerged animation pointer is loaded, left‐shifted four times, ORA'd with $00, and moved to the Y register to serve as an index for which animation frame to use.
$03CDEF	31 bytes	Sprite subroutine (JSR)	Subroutine that runs for Lemmy Koopa and Wendy O. Koopa's "descending" phase. Updates Lemmy/Wendy's Y speed and position when the phase timer isn't 0. When the timer reaches 0, this routine clears the dummy sprite slots, sets the phase timer and resets the Lemmy/Wendy phase to 0 (in pipe).
$03CE01	1 byte	Timer	How long until Lemmy/Wendy and enemies energe from the pipes.
$03CE06	1 byte	Misc.	Lemmy/Wendy/decoy speed when retreating into a pipe.
$03CE0E	72 bytes	Sprite subroutine (JSR)	Subroutine for Lemmy Koopa and Wendy O. Koopa's "hit" phase. If the phase timer is 0, this routine will increment the "hit counter" table, check if it's at 3, and if so, will zero Lemmy/Wendy's Y speed, play the falling SFX and increment the current phase table to "falling". If the "hit counter" table is not at 3, the routine will jump to code that sets the phase timer and sets the current phase to "descending". If the phase timer is not 0, this routine will check whether the sprite hit was Lemmy/Wendy or a dummy, play the appropriate SFX for hitting them, and set the appropriate animation frames.
$03CE11	1 byte	Misc.	Change to F0 to make Lemmy/Wendy and enemies immediately go back into the pipe when they have been hit. (will not play the correct! sound effect.)
$03CE1A	1 byte	Misc.	Lemmy and Wendy's HP

$03CE5A	47 bytes	Sprite subroutine (JSR)	Subroutine for Lemmy Koopa and Wendy O. Koopa's "falling" phase. Updates Lemmy/Wendy's Y speed and position - Accelerates their falling speed until it reaches approximately #$40. When their Y low position reaches #$85, the routine spawns lava extended sprites, plays the "falling in lava" SFX, sets the phase timer, and sets the current phase to "sinking in lava". The routine then branches to part of the "hit" phase subroutine that sets Lemmy/Wendy's animation frames.
$03CE71	1 byte	Misc.	Y-position where Lemmy/Wendy lands in the lava after being defeated.
$03CE7F	1 byte	Sound effect	Lemmy/Wendy falling in lava Sound Effect.
$03CE80	2 bytes	Misc.	Change to [80 05] to disable the lava splash and sound effect when Lemmy/Wendy fall into lava.
$03CE89	30 bytes	Sprite subroutine (JSR)	Subroutine that runs when Lemmy Koopa or Wendy O. Koopa are sinking in lava. Ends the level (boss fight) when their phase timer is 0, otherwise, updates their Y speed and position.
$03CE95	1 byte	Timer	How long the fadeout is on the screen before the Castle Destruction Sequence appears.
$03CE9A	1 byte	Music	Music played after Lemmy/Wendy is defeated
$03CEA7	75 bytes	Subroutine (JSR)	Contact routine for the Lemmy Koopa and Wendy O. Koopa boss fights. Runs the Mario-Sprite interaction routine, and if contact is made with Lemmy, Wendy or one of the dummies, will hurt Mario if his Y speed is negative or less than #$10. For other speeds, the routine calls the subroutines to give Mario points and boost him up, and plays the contact SFX (also the enemy hurt SFX if the sprite hit was Lemmy/Wendy). Also sets the phase timer, and increments the current phase of the fight to "hit". If the hit counter is at 2, this routine is also responsible for killing most sprites on screen (via JSL $03A6C8).
$03CEB0	1 byte	Misc.	Minimum speed Mario needs to be falling to stomp Lemmy/Wendy/decoys. Set to 01 to prevent Mario from getting unexpectedly damaged when trying to stomp them underwater. 00 causes Lemmy/Wendy/decoys to be always stomped on contact with Mario.
$03CEB8	1 byte	Misc.	Points you get for hitting Lemmy/Wendy or decoys. Default 02 - 400pts.
$03CEC2	1 byte	Sound effect	Hitting Lemmy/Wendy/enemies sound effect. (note: when hitting Lemmy/Wendy, 2 sound effects are played together.)
$03CECC	1 byte	Sound effect	Sfx that plays when Lemmy/Wendy has been hit.
$03CED0	3 bytes	ASM	[BD 34 15] Change to [80 09] (BRA $09) to make sprites on screen never die when stomping Lemmy Koopa or Wendy O. Koopa, regardless of their hit points.
$03CED4	1 byte	Misc.	Number of times minus one Lemmy/Wendy must be hit before other sprites in the room vanish.
$03CEE1	1 byte	Timer	How long Lemmy stalls after being hit.

Order: null, right, left, both (unused, same as right), null, bottom, top, both (unused, same as bottom) Due to a discrepancy between these values and the values in $049416, free scrolling can scroll the overworld 1 pixel lower than walking down can.	Direction Limits
$04824B	1 byte	Debug	Change from 80 to F0, and pushing select on the OW will cycle through Yoshi colours.
$04828D	2 bytes	ASM	Change to 80 06 to disable "Lives Exchanger" function.

$048CDE	8 bytes	Sprite tilemap related	Table of palette values used by each Yoshi color on the overworld. The table is formatted as follows: each color uses 2 bytes, in the order yellow, blue, red, green, and each 2 byte value is in big endian, meaning that the actual value is stored in the second byte. In practice, this means that the addresses you should edit are the following: - $048CDF: yellow palette. - $048CE1: blue palette. - $048CE3: red palette. - $048CE5: green palette. The values follow the YXPPCCCT properties format: to find this, subtract 8 from the palette row, and then multiply it by 2.
$048DDA	1 byte	Misc.	Change to 80 to fix a rather odd bug caused by playing a level immediately after beating a boss in Sunken Ghost Ship's original level (level 018), in which Yoshi will display extremely strangely and goal tapes/spheres will stop Mario rather than making him walk.
$048E2E	1 byte	Music	Change to 80 to fix the glitch that occurs when Mario defeats one of the Koopalings and the music on the Overworld "disappears". Also applies for Custom Music.

$048F08	1 byte	Coordinate	On which Y position Mario should be walking upwards after the intro screen (walking to Yoshi's House). (To be used with $05B15C.)
$048F7F	8 bytes	Misc.	The overworld tiles that trigger a save prompt. default is $58 (fortress), $59 (unrevealed fortress, not used in the original game because all tiles are revealed before you play them), $5D (castle), $63 (ghost house), $77,$79 (switch palaces), $7E (yellow dots from special world), $80 (Sunken Ship tile)
$048F93	1 byte	ASM	[6C] Changing this to [00] will cause all overworld tiles to show the save prompt when the corresponding level is beaten.
$048F94	72 bytes	Subroutine (JSR)	"Set up saving" routine. This copies a number of RAM addresses to the table at $1F49. You probably want to copy this to your patch (it contains lots of weirdness you don't want, so don't use the JSL to RTS trick).
$049060	4 bytes	Overworld	How may times the bits are shifted to the right to get the direction the player walks after beating a level for the layer 1 overworld tile the player stands on - 1 except for a zero in which the value isn't shifted. Indexed by $7E0DD5 in the order normal exit, secret exit 1, secret exit 2 and secret exit 3.

$049078	10 bytes	Misc.	The list of levels that have hard-coded paths. Each byte represents a level. The value 0xFF means to check for a particular overworld position instead of a level (for the pipe that Chocolate Island 2 leads to). Setting any of these levels to an invalid level (e.g. 0xFE) will disable that hardcoded path.
$049082	4 bytes	Coordinate	The 16-bit X and Y position in the overworld that will be used for the hardcoded path from the pipe to Chocolate Island 2.
$049086	68 bytes	Misc.	This is a list of all of the hardcoded paths, in the same order as the levels defined at $049078. The paths are defined as a list of all the Layer 1 tiles that Mario would encounter along the path if the path were not hardcoded. Each path ends in a level tile of some kind, which should match a visible level tile in the world.
$0490CA	68 bytes	Misc.	Hardcoded path information. For each tile in the list at $049086, there is a corresponding byte in this list. These values determine the direction Mario should face while walking along that path. $00 = Up, $02 = Down, $04 = Left, $06 = Right
$04910E	18 bytes	Misc.	Hardcoded path data. A list of offsets into the fields at $04:9086 and $04:90CA. This list corresponds to the list at $04:9078; this offset tells where the tile data for that level's hardcoded path begins.
$049136	1 byte	Misc.	DEBUG: Change to F0 to make player warp to Star Road if Select is pressed on top of Yoshi's House (tile 0x56).
$049171	1 byte	Sound effect	Sound effect played when warping over a star road tile.

$0491E3	1 byte	Music	[FB] Change to F9 or FC to use sound effect when entering a level.
$04922E	1 byte	Misc.	Change to 00 to make Mario stay in place after completing a level on the overworld (as opposing to moving to the next level)
$049264	1 byte	Misc.	On the overworld, Mario always faces you after he moves onto a level tile. Change the 09 to a 00 to disable that. Mario will continue facing the last direction he was moving towards after he moves onto a level tile.
$049291	3 bytes	Debug	If you replace this with "4C AF 92" (JMP $92AF), it will enable to walk in unrevealed paths on the overworld. (But it will not work correctly with star road warps)
$049414	2 bytes	Mario physics	Speed of Mario on the OW (Higher = faster). First byte is normal ground, second is stairs.
$049416	8 bytes	Overworld	Max range for overworld scrolling when walking. 16-bit. Order: left, top, right, bottom. Due to a discrepancy between these values and the values in $048221, free scrolling can scroll the overworld 1 pixel lower than walking down can.	Direction Limits
$049426	10 bytes	Misc.	List of layer 1 overworld tiles that allow mario to walk from one map to another ("exit level tiles" in lunar magic)
$04965C	1 byte	Overworld	Change to 80 (BRA) to make Mario stand on OW tiles 6A through 6D, instead of swimming through them.
$04968D	24 bytes	Sound effect	Code that handles what overworld tiles don't play a SFX when stepped on. The tile numbers are used in 16-bit. $04968D - Change [AD C1] to [80 10] to make overworld star/pipe tiles play the "beep" sound when stepped on. $0496A0 - Sound effect that plays when Mario steps on a level tile. Change to 00 to disable.
$04969F	6 bytes	Sound effect	Replace [A9 23 00 8D FC 1D] with [EA EA EA EA EA EA] to disable the "beep" when Mario moves onto a level tile.
$049831	84 bytes	Overworld	Handles moving the camera when Mario moves on the overworld. Checks against the scroll bounds of the overworld at $049416. Does not move the camera when the Valley of Bowser earthquake ($7E1BA0) is happening, or when the player is on a submap.
$049885	65 bytes	Subroutine (JSR)	Calculator for the players overworld tile position. Before calling this function $00 must contain the 16 bit X position of the player, $02 must contain the 16 bit Y position of the player, and X must be 0 or 1 (luigi, mario). Additionally, A must be 16 bit.
$0498CA	1 byte	Overworld	Initial Y speed of the player when walking up to Yoshi's house. Each frame, they moves up one pixel, and then they're moved down this many 256ths of a pixel. Since the default value for this is #$80, this means Mario moves up #$100-#$80=#$80 pixel 256ths, which is half a pixel.
$0498F0	1 byte	Coordinate	At which Y position Mario should stop the intro march on the overworld (walking to Yoshi's house after start of new game). Default: $78.
$049964	170 bytes	Overworld	A big bunch of tables for which exits on the overworld lead to where. $049964 to $0499A9: Five bytes for each entry that describe where each exit is (the tile Mario enters). First two bytes are Y position ($1F19), then comes X position ($1F21), then finally the submap ($13C3). $0499AA to $0499EF: Five bytes for each entry that describe where each exit leads (the tile Mario ends at). Same format as above. $0499F0 to $049A0D: Two bytes for each entry, to additionally describe the target. First comes Y high divided by 16 ($1F21), then comes X high divided by 16 ($1F1F). If an exit is not present at the exact listed position, Mario is not moved, and tries to exit from the same tile again.
$049AC5	460 bytes	Layer 3	Level names. It's almost raw tilemaps ready to be uploaded to VRAM (no YXPCCCTT), but if the highest bit is set, it gets cleared and it's the end of the area. However, it's cut to small chunks. See $04A0FC (0x222FC) for how they're put together.
$049D22	2 bytes	Coordinate	Position of OW level names. Increase/decrease by 1 to make it move up to the right/left, increase/decrease by 20 to make it move down/upwards. Note that #$8B should be considered the low byte for the address, not #$50.
$049EA7	162 bytes	Misc.	Two bytes per tile, starts at tile $01 and goes to $51. First byte is X distance mario moves across tile Second byte is Y distance mario moves across tile The distance is based on walking right for a horizontal path and walking down for a vertical path (see entry for $04:9F49)
$049F11	2 bytes	Overworld	[FC F8] Change to [10 04] to allow overworld path tile 36 to be used as the missing water path tile. Must be combined with $049FB3, $04A020, and $04A04D.
$049F49	162 bytes	Misc.	Two bytes per tile, starts at tile $01 and goes to $51 If the two bytes are $01,$00 then the tile is a horizontal path If they are $00,$01 then a vertical path. No other values were used in game It seems odd to use two bytes to do this, so it might be worth experimenting with other values
$049FB3	2 bytes	Overworld	[00 01] Change to [01 00] to allow overworld path tile 36 to be used as the missing water path tile. Must be combined with $049F11, $04A020, and $04A04D.
$049FEB	81 bytes	Misc.	One byte per tile, starts at tile $01 and goes to $51 Mario pose while walking 0 - Mario Vertical 4 - Mario Horizontal 8 - Mario Swimming Vertical C - Mario Swimming Horizontal 10 - Entering Level 14 - Climbing 18-FF - Unused Only multiples of 4 seem to be used, using a value inbetween just seems to result in oddly animated versions of the normal values
$04A020	1 byte	Overworld	[08] Change to [0C] to allow overworld path tile 36 to be used as the missing water path tile. Must be combined with $049F11, $049FB3, and $04A04D.
$04A04D	1 byte	Overworld	[36] Change to [87] to allow overworld path tile 36 to be used as the missing water path tile. Must be combined with $049F11, $049FB3, and $04A020.
$04A0FC	186 bytes	Layer 3	How to put level names together. Format: 16 bits/entry. First byte contains the offsets to the second and third parts (lowest four bits there is third part, upper four bits there is second), while the second byte (except the highest bit, which is unused) contains the offset to the first part. Note that those offsets aren't direct, they point to $049C91, $049CCF, or $049CED (note: those offsets are 16bit), which contains the real offsets to $049AC5.
$04A1B6	586 bytes	Empty	Unused data
$04A400	307 bytes	Overworld border	Layer 3 Border Tile Data: The 95s, 96s, and 97s are the tiles used for the Mushrooms, Stars, and Fire Flowers (respectively).

$04DA1D	44 bytes	Overworld	A 22-byte table of Layer 1 overworld tile numbers that change into other tiles, followed by a 22-byte table of the tile numbers that they become. Entries $09 [53->43], $0A [52->44], and $15 [54->23] correspond to tiles that are unused in the original SMW, so they could be changed to other tile numbers if need be. (This is how things such as revealing level tiles work: tile numbers from the first list are transformed into the corresponding tiles from the second list when activated.)
$04DAAD	6 bytes	Overworld	Routine that decompresses and uploads the overworld's layer 2 tilemap to the buffer at $7F4000. It's just a wrapper that JSRs to $04DC6A and preserves the processor flags (PHP : JSR : PLP). You can JSL to this routine to reload the overworld's layer 2. This can be useful if modifying $7F4000 (for example, if you want to load the overworld after the staff roll cutscene has played out).
$04DABA	53 bytes	Subroutine (JSR)	Subroutine that decompresses LC_RLE2 data.
$04DBC8	7 bytes	Music	Music tracks used by the different submaps, indexed by submap ID ($1F11).
$04DC6A	68 bytes	Overworld	Routine that decompresses and uploads the overworld's layer 2 tilemap to $7F4000 (including all the event data). Additionally, it loads all the currently activated events into the tilemap. If you need this, call the JSL wrapper at $04DAAD.
$04DD57	54 bytes	Subroutine (JSR)	Subroutine that decompresses LC_RLE1 data.
$04DD8D	1484 bytes	Overworld	A table used by layer 2 events. It contains 0x173 four byte entries. The first two bytes in each entry are for the source offset ($0C8000) (also decides size), the last two are for the target offset ($7F4000).
$04E359	242 bytes	Overworld	Table that tells how many layer 2 tiles each event reveals and where in the table ($04DD8D) they start. This table contains 121 16-bit values; one for each event, and one to tell where $04DD8D ends.

$04E5A7	5 bytes	Overworld	Layer 1 tile numbers that have a destruction event associated with them. Essentially, the "before" tiles.
$04E5AC	5 bytes	Overworld	Top tile to write after each destruction, in the order of $13D0. The table is only used for two-tile destructions (like the castles), so the first three bytes are normally unused.
$04E5B1	5 bytes	Overworld	Bottom/base tile to write after each overworld tile destruction, in the order of $13D0.
$04E5B6	32 bytes	Overworld	Layer 1 tilemap locations (16-bit) for each of the castle/fortress/switch palace destruction events.
$04E5D6	16 bytes	Overworld	Which event numbers will trigger castle/fortress/switch palace tile destruction sequences. Due to a coding error by Nintendo, the table is treated as 0x18 bytes long when it's really only 0x10 bytes.
$04E5E6	8 bytes	Overworld	The overworld tiles that will allow triggering a save prompt when an event has already been cleared. Tile must also exist in the list at $04:8F7F.
$04E5EE	82 bytes	Subroutine (JSR)	Subroutine that runs events at level end.
$04E660	1 byte	Misc.	Level that triggers overworld Earthquake sequence

One overworld sprite has 5 bytes: Byte 1 - sprite number Byte 2 - X-Pos, low Byte 3 - X-Pos, high Byte 4 - Y-Pos, low Byte 5 - Y-Pos, high Data is only read once, on titlescreen load. (Which also explains the bug that occurs with the titlescreen showing an unnecessary cloud tile.)
$04F666	6 bytes	Coordinate	X positions of the overworld ghost sprites, relative to their corresponding main map ghosts. Two bytes each. The small size of this table is why you can't have ghosts in any slot other than the last three.
$04F66C	6 bytes	Coordinate	Y positions of the overworld ghost sprites, relative to their corresponding main map ghosts. Two bytes each. The small size of this table is why you can't have ghosts in any slot other than the last three.
$04F709	1 byte	Overworld	Submaps on where to disable the thunder effect (originally used in Valley of Bowser). #$80 - Main map #$40 - Yoshi's Island #$20 - Vanilla Dome #$10 - Forest of Illusion #$08 - Valley of Bowser #$04 - Special World #$02 - Star World #$01 - Unused Note that the bits in this address disables the thunder in this submap, so to disable it everywhere, #$FF is the correct value. This address affects both colors and sound.
$04F737	1 byte	Music	Sound effect for the thunder in Valley of Bowser.
$04F744	1 byte	Timer	How long the lightning flash stays on screen (Bowser's Valley)

$04FCD3	1 byte	Sprite tilemap related	Tile to use for Yoshi's House smoke (2)
$04FD0A	6 bytes	Sprite physics	Turn timer table for the OW Boo sprite. The table is formatted as follows: 3 pair of speeds, each one used for the X, Y and Z direction respectively. In each pair, the first value is used when having positive speed and the second when turning around to negative speed. The timer is checked by doing AND between the value in this table and the table at $0E25 (which increases every frame), and updating the direction when the result is not 0.
$04FD10	10 bytes	Sprite physics	Acceleration table for the overworld Bowser and Boo sprites. The table is formatted as follows: 5 pairs of values, each pair having a right and left acceleration value, where the first 2 are OW Bowser's X and Y acceleration respectively, and the others are OW Boo's X,Y and Z acceleration respectively.
$04FD1A	10 bytes	Sprite physics	Maximum speed table for the overworld Bowser and Boo sprites. The table is formatted as follows: 5 pairs of values, each pair having a right and left speed value, where the first 2 are OW Bowser's X and Y speed respectively, and the others are OW Boo's X,Y and Z speed respectively. The last pair of values ($01,$FF) is also used to initialize the Z speed of the OW Boos, but for some reason they only read the first value.

EAEA0A - Every half pipe (every pipe is 2-toned). EAA9xx - All pipes are same colour (xx=00, 01, 02 or 04). Must be combined with $05:87A4. Warning: Does not have any effect on ROMs LM 1.7 has been used on.
$0581BB	64 bytes	Misc.	Map16 tileset-specific table. Each bit (from high to low) corresponds to one tile. When the game sets up tile pointers, if the bit is set, it writes and then increments (by 2) P1 (which is initialized to the value at $058000 + (Tileset * 2)), otherwise it writes and increments P2 (initialized to $(0D)8000).
$0582C8	114 bytes	Subroutine (JSR)	This routine is used within the level clear to set $7EC800-$7EFFFF to #$25.

$05A590	23 bytes	Misc.	Which levels have message boxes. Different values here corresponds to $13BF. If the highest bit (#$80) is set, it tells that message 2 is used for that level; if clear, message 1 is used. Most likely not used when LM is done with the ROM.
$05A5D9	2854 bytes	Layer 3	All the message box texts. They're almost raw tilemaps (doesn't contain YXPCCCTT data) to be uploaded to VRAM, but setting the highest bit makes it add a newline too.
$05B106	2 bytes	Misc.	Time when to show text after expanding/shrinking the Message Box window. 1st byte determines when to show the message. 2nd byte determines how fast to hide the message. Edited values can't be higher than the default hex values.

It handles the windowing HDMA, the stripe image upload, and things such as teleporting to the overworld after the intro screen. $05B129: [9C 9F 0D] Change to [EA EA EA] to prevent HDMA from getting disabled AFTER a message box has been displayed. Use with $05B296. $05B15C: [8E] The Y position on which to start the march to Yoshi's House after the intro screen. To be used with $048F08. $05B15D: [8D 19 1F] ASM code that stores the player's starting Y position to its RAM address, $1F19. Lunar Magic changes this to [EA EA EA] if you move the Mario OW sprite around, thus disabling the intro march (and its effects, such as storing '0' to the amount of levels cleared). If you want to undo this effect, change it back to [8D 19 1F]. $05B160: Side exit subroutine. It can be JSL'd to. $05B189: [D0 CF] Change to [EA EA] to prevent the message that pops up in the intro screen from exiting the level. (It will act exactly the same as a message in any other level.) $05B21D: [39] Tile properties of the Layer 3 tiles in message box messages in YXPCCCTT format. (Note: Lunar Magic ASM hacks render this address unused.) $05B296: [8D] Change to [0C] to prevent HDMA from getting disabled WHILE a message box is being displayed. Use with $05B129.
$05B29B	64 bytes	Sprite tilemap related	This is the 8x8 tilemap data for the sprites used on the switch palace messages (dotted and '!' block). The first byte in each in the tile, the second byte is the YXPPCCCT data.
$05B329	33 bytes	Subroutine (JSL)	"Give coins" subroutine. If you JSL to it, it will give the player the number of coins equal to the value in A.
$05B34A	17 bytes	Subroutine (JSL)	Subroutine that gives the player a single coin. It handles the green star block as well. $05B34E is the sound this generates.
$05B375	488 bytes	Layer 3	Title screen stripe image data (the part that appears right as the title screen loads up).
$05B6FE	203 bytes	Layer 3	Tilemap of the erase file select dialog. ("ERASE MARIO A . . . EMPTY", etc.)

$05B872	85 bytes	Misc.	1 / 2 player game stripe image data.
$05B93B	48 bytes	Misc.	Destination VRAM addresses for animated tiles. There are 6 bytes, 3 16-bit addresses, for each of the 8 possible animation frames (index = (frame & 7) * 6), and their values get stored to $0D7C, $0D7E, and $0D80 during the animation handling routine. (The last 6 bytes are actually unused, since SMW never uses animation frame 7 for anything.)
$05B96B	24 bytes	Misc.	This table determines how a certain tile should vary its animation. 00 = always the same, 01 = change depending on $14AD, $14AE, or $14AF (P-switch timers and on/off switch), 02 = change depending on $1931 (FG/BG tileset number). It is indexed by the animation frame times 3, or (($14 & #$07) * 3), and each of the 8 possible animation frames uses one group of 3 bytes. Note that the last 6 bytes overlap with the table at $05B97D.
$05B97D	15 bytes	Misc.	Table that determines, for tile animations that can have one of two states, which address to use to determine the state (i.e. any animation for which its corresponding value in the table at $05B96B is 01). The address used is $14AD plus this value, so 00 = blue P-switch, 01 = gray P-switch, 02 = on/off switch. This table is only 15 bytes long rather than 24 because all of the 2-state animations are updated on animation frame 0, 1, 2, 3, or 4, never 5, 6, or 7. Note also that the last byte overlaps with the table at $05B98B.
$05B98B	14 bytes	Misc.	Table, indexed by FG/BG tileset. Determines which group of animated tiles to use for a certain tileset, such as conveyor belts, stars, lava, etc.
$05B999	416 bytes	Misc.	Frame data for animated tiles. Each group of 8 bytes is one set of tile animation, and each pair of bytes is one frame. The numbers are offsets forming the lower two bytes of pointers to the table data at $7E7D00. (For instance, the first two bytes = 00 95 -> data at $7E9500.) There seems to be no discernable pattern to which tiles are uploaded where in VRAM, though.
$05BB39	109 bytes	Subroutine (JSL)	The routine that handles tile animation. It reads the animation data from the table at $05B999 and, based on that and a few other factors (such as tileset and blue P-switch status), sets the pointers to the tile data in the table at RAM $7E0D76.
$05BBA6	90 bytes	Empty	Unused data.
$05BC87	30 bytes	Pointer	Pointers to the scroll sprite main routines for Layer 1 scrolling.
$05BCB8	30 bytes	Pointer	Pointers to the scroll sprite main routines for Layer 2 scrolling.
$05BCF0	30 bytes	Pointer	Pointers to the scroll sprite init routines for Layer 1 scrolling.
$05BD17	30 bytes	Pointer	Pointers to the scroll sprite init routines for Layer 2 scrolling.
$05BEA6	3 bytes	ASM	[9C 11 14] Change this to EA EA EA to make Layer 2 Sideways Scroll not disable horizontal scroll.
$05C4F2	6 bytes	ASM	Change from [85 22 A9 01 85 23] to [38 69 02 85 22 EA] in order to make the Layer 3 tides scroll to the right instead of the left. (Nothing is stored to the high byte of Layer 3 X position, however, so if you adjusted the tide to be asymmetrical, this may not give the wanted result.) Only applies to the graphical part of the Layer 3 tide.
$05C71B	1 byte	Misc.	Layer 2 on/off switch lower limit. The lower this number, the further down the screen layer 2 will go before stopping.
$05C71D	1 byte	Misc.	Layer 2 on/off switch upper limit. The higher this number, the further up layer 2 will go before it will start descending again.
$05C7BC	3 bytes	Misc.	Change to A9 08 EA and the background will start scrolling fast with generator F4 without having to touch platform C1
$05C7CB	2 bytes	Misc.	Maximum speed of layer 2 scrolling during "Fast BG Scroll" (sprite F4).
$05CA5C	5 bytes	Sprite Misc.	What direction Layer 2 will start out moving when each variant of the Layer 2 Scroll sprite (sprite EA) is used. In order: Range 12, Range 08, Range 05, Range 06, Range 05 (alternate). 00 -> down, 01 -> up.
$05CBF5	10 bytes	Timer	Determines the distance for Layer 2 to scroll when using each variant of the Layer 2 Scroll sprite (sprite EA), outside of the acceleration/deceleration period. In order: Range 12, Range 08, Range 05, Range 06, Range 05 (alternate); each type corresponds to a pair of bytes here. The first byte of each pair is for the first movement, and the second is for every time it moves after that. The data is roughly how much time will be spent scrolling at full speed, not the actual distance, so the scroll speed and acceleration affect this.
$05CBFF	8 bytes	Subroutine (JSL)	Jumps to Level End Scorecard Subroutine
$05CC16	75 bytes	Layer 3	Start of course clear message tilemap. $05CC1A (10 bytes) is 'MARIO' tiles and attributes used in the end-of-level scorecard $05CC28 (12 bytes) is "COURSE" and attributes at end of level scorecard. $05CC36 (10 bytes) is "CLEAR" and attributes at end of level scorecard.
$05CC61	5 bytes	Misc.	'LUIGI' letters used in the end-of-level scorecard (uses the same attributes as the MARIO letters)
$05CC66	2 bytes	Misc.	Change to 80 1C to prevent the player from getting a free 1UP at the goal if the tens digit of your bonus star counter and the tens and ones digits of your time are all the same
$05CC85	1 byte	Misc.	Change to 00 to disable "Course Clear" from appearing.
$05CCC4	1 byte	Misc.	Number of LUIGI tiles to use in the end-of-level scorecard
$05CD2C	1 byte	Timer	Time it takes for Bonus! to appear after hitting the goal tape.
$05CD3F	35 bytes	Layer 3	Stripe image for the bonus star counter in end of level scorecard. $05CD3F is the main "BONUS! ★x__" text, with the __ being blank tiles reserved for the bottom of the number of stars. A second header starting at $05CD5A handles two additional blank tiles, used for the top of the numbers.
$05CD62	20 bytes	Layer 3	Table of tiles used to display the amount of bonus stars received in the end level routine. Starts with top tile of 0, bottom tile of 0, top tile of 1, bottom tile of 1, etc. Notably, there's no header OR end byte.
$05CD79	1 byte	ASM	Changing this byte to [80] will disable the bonus counter in the 'Course Clear' screen.
$05CDD8	1 byte	ASM	Changing this byte to [80] will disable the drumroll sound effect, and the Timer and score tallying at the 'Course Clear' screen.
$05CDE4	1 byte	Sound effect	Drum Roll (tallying points) Sound Effect.
$05CE7A	1 byte	Misc.	Time Multiplier for every second (use with $05CE92) must be a multiple of 10.
$05CE92	1 byte	Misc.	Time Multiplier for every second (use with $05CE7A) must be a multiple of 10.
$05CF1B	3 bytes	ASM	Change to EA EA EA and the player will receive no bonus stars at the end of the level.
$05CF49	1 byte	Sound effect	Drum Roll Finishing Sound Effect.
$05CFEA	22 bytes	Empty	Empty.
$05D000	1536 bytes	Misc.	Tile data for all Layer 1 overworld tiles, #$00-#$BF (but BF doesn't show up in LM no matter what you set it to). 8 bytes per 16x16 tile = 2 bytes per 8x8 tile. (TTTTTTTT YXPCCCTT.) Order in which the pairs of bytes go inside a 16x16 tile: upper-left, bottom-left, upper-right, bottom-right.
$05D608	96 bytes	Overworld	Which events are triggered by which level. Indexed by level ID, aka $13BF.
$05D668	160 bytes	Empty	Unused data.
$05D708	8 bytes	Level data	Layer 1, 2 (FG,BG) Initial Position. FG values (4 bytes) are first. BG values (4 values) are last.
$05D710	16 bytes	Level data	Vertical scroll settings for layer 2 background. The values in this table are for RAM $7E:1414. The index to this table is the %ssss from the %ssssyyyy in table ROM $05:F000.
$05D720	16 bytes	Level data	Horizontal scroll settings for layer 2 background. The values in this table are for RAM $7E:1413. The index to this table is the %ssss from the %ssssyyyy in table ROM $05:F000. The maximum %ssss in SMW is %0111, thus indexes %1000 through %1111 are unused and are available if you want to invent more scroll settings for layer 2.
$05D730	16 bytes	Level data	Mario Y-Position (main and midway entrances)
$05D740	16 bytes	Level data	Mario Y-Subscreen Positions (main and midway entrances)
$05D750	8 bytes	Level data	Mario X-Positions (main and midway entrances). 8th byte unused?
$05D758	8 bytes	Level data	Mario X-Subscreen Positions (main and midway entrances). 8th byte unused?
$05D760	6 bytes	Misc.	The tileset that each no-Yoshi intro intro is used with. Same order as $05D766 (0x2D966). The last one seems to be unused.
$05D766	18 bytes	Pointer	List of 6 pointers to the "Get off Yoshi" level intros. In order: Ghost House, Castle Entrance 1, No Yoshi Sign 1, No Yoshi Sign 2, No Yoshi Sign 3, Castle Entrance 2.
$05D778	18 bytes	Pointer	List of pointers to the Layer 2's for the "Get off Yoshi" intro levels. Same order as for 2D966
$05D796	857 bytes	Subroutine (JSL)	The main level data loading routine. $05DAE5 is which level has the variable exits that changes depending on coins, timer, and yoshi coins. To disable the variable properties of this level, change $05DAE6 to 80. $05DA19 is the start of the code for checking whether or not the level should use a No-Yoshi intro. Change to [4C D7 DA] to disable all No-Yoshi intros, including those for ghost houses and castles.
$05DA1D	1 byte	Level number	Any level with a translevel number greater than or equal to this will use the "No Yoshi Sign 2" intro if the no-Yoshi intro is not disabled, regardless of tileset.
$05DA4B	1 byte	Level number	One of five translevels that will use a dark-background castle intro if the level is set to tileset 1 and a no-Yoshi intro is enabled. This one is 31 (Front Door) by default.
$05DA4F	1 byte	Level number	One of five translevels that will use a dark-background castle intro if the level is set to tileset 1 and a no-Yoshi intro is enabled. This one is 32 (Back Door) by default.
$05DA53	1 byte	Level number	One of five translevels that will use a dark-background castle intro if the level is set to tileset 1 and a no-Yoshi intro is enabled. This one is 34 (#7 Larry's Castle) by default.
$05DA57	1 byte	Level number	One of five translevels that will use a dark-background castle intro if the level is set to tileset 1 and a no-Yoshi intro is enabled. This one is 35 (Valley Fortress) by default.
$05DA5B	1 byte	Level number	One of five translevels that will use a dark-background castle intro if the level is set to tileset 1 and a no-Yoshi intro is enabled. This one is 40 (#3 Lemmy's Castle) by default.
$05DAEF	186 bytes	Subroutine (JSR)	The routine that loads level data for the sublevels of the level with the variable screen exits (i.e. level 24, or Chocolate Island 2, in the original SMW).
$05DB08	18 bytes	Pointer	Pointers to the layer 1 data that should be loaded for Chocolate Island 2.
$05DB1A	18 bytes	Pointer	Pointers to the sprite data that should be loaded for Chocolate Island 2.
$05DB2C	18 bytes	Pointer	Pointers to the layer 2 data that should be loaded for Chocolate Island 2 (all identical).
$05DBA9	1 byte	Level number	Level number for bonus game after gaining 100 bonus stars from a goal tape.
$05DBAA	1 byte	Level number	Level number for yoshi wings bonus stage.
$05DBAC	29 bytes	Subroutine (JSR)	The routine that handles setting the level to warp to when Yoshi gets the wings. (Level xC8.)
$05DBB3	1 byte	Misc.	Change to 60 (RTS) to make it so Yoshi wings use the normal screen exit instead of forcing a warp to level C8/1C8. This allows you to use pipes/doors in Yoshi wings levels. However, bonus games still remain incompatible. (Make sure to add a screen exit on every screen a player could possibly collect Yoshi wings if you use this.)
$05DBC9	2 bytes	Coordinate	Position of lives counter on the overworld.
$05DBF2	72 bytes	Subroutine (JSL)	Routine that draws the life counter on the overworld border. You can JSL to it to update the counter if changing the player's lives while on the overworld.
$05DC3A	12 bytes	Subroutine (JSR)	Hex -> Dec subroutine, ends with RTS. Only used for displaying the player's lives on the overworld. Input: A (8-bit) = the value to be converted Output: A = ones digit. X = tens digit.

$05F600	512 bytes	Level data	Table for each level in iuveeeee format. i = disable No Yoshi Intro flag, u = unknown vertical level positioning flag, v = vertical level positioning flag, eeeee = screen # that the primary entrance is on.
$05F800	512 bytes	Level data	Part of the Secondary Entrance information; each byte is one of the secondary entrances. The byte is the low byte of the destination level number. The high bit (0x100 vs. 0x000) is stored in another table. Note that, as of LM v2.50, this table may be dynamically moved to accomodate the size of the new secondary exits. It can be found at `read3($0DE191)`.
$05FA00	512 bytes	Level data	Part of the Secondary Entrance information; each byte is one of the secondary entrances. The low 4 bits are the Y position for Mario; offsets into a table at SNES addresses $05:D730 and $05:D740. The next two bits are the FG initial position, indexing into the table at SNES address $05:D708. The highest 2 bits are the BG initial position, indexing into the table at SNES address $05:D70C. Note that, as of LM v2.50, this table may be dynamically moved to accomodate the size of the new secondary exits. It can be found at `read3($0DE198)`.
$05FC00	512 bytes	Level data	Part of the secondary level information. The low 5 bits are for the destination screen number. The high 3 bits are the X position for Mario; offsets into a table at SNES addresses $05:D750 and $05:D758. Note that, as of LM v2.50, this table may be dynamically moved to accomodate the size of the new secondary exits. It can be found at `read3($0DE19F)`.
$05FE00	512 bytes	Level data	Part of the Secondary Entrance data; each byte corresponds to an entrance. The lowest 3 bits are the Mario action. The next bit is the high bit of the secondary entrance's level number. The highest bit is set when the destination level should be slippery. Note that, as of LM v2.50, this table may be dynamically moved to accomodate the size of the new secondary exits. It can be found at read3($05DC81).
