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.	Powers of 10 table for 6-digit* HexToDec routine at $009012 used to display the player's score. Note: These are 16-bit words, but are handled as 32-bit subtraction for the low and high words individually. *SMW displays the score as 7 digits, but the score is actually a 6-digit (decimal) number stored internally, the 7th digit "0" is a static tile not part of this number.	16-bit values
$009012	51 bytes	Subroutine (JSR)	6-digit* HexToDec subroutine to write a player's score into status bar. Call with Y = #$00, X as the position to write to on the status bar (standard is #$14), and $00-$03 as the score to write (in hexadecimal). Note that this routine does not remove leading 0s; that is handled at $008EDE and $008F0C. Works like this: count how many subtractions by 10ⁿ (with n=5) without the difference going into the negatives; that number of subtractions is the digit for the 10ⁿs place. Then repeat but with 10^n-1. This is the "left-to-right" version of base conversion using repeated subtraction to emulate the 32-bit division by 10ⁿ. *SMW displays the score as 7 digits, but the score is actually a 6-digit (decimal) number stored internally, the 7th digit "0" is a static tile not part of this number.
$009045	12 bytes	Subroutine (JSR)	The hexadecimal to decimal subroutine (in short HexToDec) which converts a hexadecimal 8-bit value into a decimal string. To use for JSL, use `JSL $00974C` instead. Input: -A: 8-bit value to convert Output: -A: 1s digit (calculated via repeated subtraction until < 10; “modulo” by 10) -X: 10s digit (calculated via how many subtraction until A < 10; “quotient” division by 10)
$009051	40 bytes	Subroutine (JSR)	Bonus stars (small 8x8 digits) HexToDec routine. Unknown why Nintendo didn't decide to use $009045 instead, since the bonus stars are 8-bit and other digits are also 8-bit and they use $009045. Note: this routine alone produces mere 1s and 10s place, so the numbers will be 8x8 instead of 8x16. The code at $008FAF will convert the digits to tile numbers of 8x16 digit graphics.
$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".
$0091AC	1 byte	Misc.	Number of coins needed to get an 1up from the green star block.
$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.

$0093B0	1 byte	Sprite tilemap related	YXPPCCCT properties for "Nintendo Presents".
$0093C0	5 bytes	Sound effect	Code responsible for the "Nintendo Presents" logo sound effect. $0093C1 (1 byte) is the sound effect ID ($01). $0093C3 (2 bytes) is the port ($1DFC).
$0093C6	1 byte	Timer	How long "Nintendo Presents" stays on the screen before disappearing.
$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.

$00955F	1 byte	Misc.	GFX File loaded for Credits font
$009586	4 bytes	Level number	Which level to use for the Yoshi's House part in the credits. 'A9 28 A0 01'. Do not change A9 and A0. 28 is the low byte of the level (Note: Level number + 24), 01 is the high byte.
$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.
$00974C	4 bytes	Subroutine (JSL)	Calls the hexadecimal to decimal subroutine (in short HexToDec) to convert a hexadecimal value into a decimal string at $009045 and ends in an RTL. Input: -A (8-bit value). Output: -A: 1s digit (repeated subtraction remainder (“modulo”) once A < 10) -X: 10s digit (the “quotient” of A divided by 10)
$00980F	2 bytes	Coordinate	16-bit X position of Mario when he starts at the Iggy / Larry room. First byte = X lo, second byte = X hi (this byte is not recommended to change).
$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.
$009C87	1 byte	ASM	Change D0 (BNE) to 80 (BRA) to never make the titlescreen 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.

$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. Changing the first three bytes from [8D 01 07] to [EA EA EA] will disable the titlescreen back area color from changing.
$009D6D	1 byte	Misc.	How many exits you need to get the *96 icon.
$009D71	1 byte	Misc.	First tile of the *96 icon.
$009D73	1 byte	Misc.	Second tile of the *96 icon.
$009D8B	1 byte	Palette	Palette for "number of levels beaten" in the Title Screen's Game Selection Menu (stored in YXPCCCTT format, but kind of screwy; value 30 seems to work well, though)
$009DB5	69 bytes	Subroutine (JSR)	The subroutine that checks if a saved game file is blank or not. When this subroutine returns, if Z = 0, the file is a new one.
$009E25	1 byte	Misc.	Amount of lives to start with, minus 1.
$009E35	2 bytes	ASM	Set powerups at game start. ($19 = #$00, small Mario.)
$009E6A	10 bytes	Misc.	Table containing the number of possible options for different menus, in 16 bit format. The entries are as follows: - $0002: unused - $0004: file select menu - $0002: player select menu - $0002: unused - $0004: file erase menu
$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.)

$00A82E	1 byte	Misc.	GFX File loaded for "MARIO START!", "GAME OVER", etc.
$00A8C3	104 bytes	Sprite Misc.	26x4 byte table, Sprite GFX list. Normal levels can use 00-0F, but the following values have also been observed: 10: [00 00 00 08] Unused? 11: [10 0F 1C 1D] Overworld 12: [00 01 24 22] Morton, Roy, Ludwig 13: [00 01 25 22] Iggy, Larry, Reznor 14: [00 22 13 2D] Castle destruction sequence 15: [00 01 0F 22] Walking home during the credits 16: [00 26 2E 22] Yoshi's House during the credits 17: [21 0B 25 0A] Boss list from the credits 18: [00 0D 24 22] Bowser 19: [2C 30 2D 0E] THE END screen

$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	7 bytes	Level number	The level numbers that triggers the seven castle destruction sequences. The first byte is for scene 1, the second is for scene 2, and so on.
$00C9AE	1 byte	Level number	One of the two level numbers that triggers the credits scene. The other is 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: Free-roaming mode (F0 = enable)
$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.
$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
$00CF75	1 byte	Mario tilemap	[3F] Mario shooting fireball on ground pose.
$00CF7B	1 byte	Mario tilemap	[16] Mario shooting fireball in air pose.
$00CF90	1 byte	Mario tilemap	[0F] Mario turning around while holding item pose.
$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

$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
$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	34 bytes	Mario physics	Mario's minimum X speeds on flat ground and on slopes. The table is in the order of $13E1. Each entry gets two bytes; the second byte is the actual speed ($7B), while the first is the accumulating fraction bits ($7A). The last 8 bytes of the table seem to be unused.
$00D5CA	30 bytes	Mario physics	How much Mario moves while on slopes, added to $7B. Values correspond to $7E:13E1 (slope type) divided by four. Every second byte is unused.
$00D5E8	1 byte	Mario physics	X speed of player as they're floating in water freely in a level where a Layer 3 tide is active. (Does not affect the speed given when the player manually moves around on their own horizontally.)
$00D5EA	1 byte	Mario physics	X speed of player as they're floating in water AND standing on a platform (like the floating grassy platforms) in a level where a Layer 3 tide is active. (Does not affect the speed given when the player manually moves around on their own horizontally.)
$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 and $13DA, $96 and $13DC) by X and Y speed ($7B and $7D). The player's position is actually measured in units of “subpixels” -- 1/16th of a pixel for more precise movement, by using fixed-point arithmetic. It is calculated like this: Take $7B/$7D, divide by 16 (LSR #4), and that is the amount of movement per frame, in pixels the player will be offset by.	Math example
$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.

$00DFDA	50 bytes	Mario tilemap	Tile expansion table (8x8 tiles in GFX00 used by Mario)
$00E00C	192 bytes	Mario tilemap	Mario upper tile.
$00E0CC	192 bytes	Mario tilemap	Mario lower 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.
$00E2D3	1 byte	Debug	DEBUG: Infinite star (set to 00 to activate)
$00E30D	1 byte	Misc.	How many palettes to cycle through when Mario/Luigi is invincible, -1
$00E34F	4 bytes	Misc.	Change to EA EA EA EA (NOP #4) and all forms of Big Mario will not go into the ground a few pixels.
$00E35D	3 bytes	ASM	Change to $EA,$EA,$EA (NOP #3) to cancel out Mario moving up and down one pixel while walking and running. This is useful if you are using more than three animation frames for walking/running, and thus can be worked into your GFX/tilemap accordingly.
$00E364	1 byte	ASM	Change to $80 (BRA) to disable Mario from being offset vertically by one pixel while running on the wall (using the purple triangles). This should be combined with $00E34F and $00E35D for the complete effect.
$00E3AA	1 byte	Misc.	Which animation frame value to start pulling tilemaps from the size-independent table
$00E3FE	1 byte	Misc.	power-up that shows the cape graphics
$00E4B9	33 bytes	Misc.	Values stored to $13E1 for each slope tile. Rather than being indexed by the tile's Map16 tile number, this table is instead indexed based on the actual slope tile used; for instance, gradual slopes have 8 tiles (4 left-facing and 4 right-facing) whereas normal slopes have 4 (2 left-facing and 2 right-facing). The slopes in the table by index are: 00 - Gradual 08 - Normal 0C - Steep 0E - Purple Triangle 10 - Very Steep Ledge-edge (from standard object 13) 12 - Upside-down Steep (unused) 14 - Upside-down Normal (unused) 18 - Conveyors 1C - Very Steep 20 - Flat ground

$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.
$00E5C8	106 bytes	Misc.	Indices to the tables at $00E4B9-$00E53D and $00E632, when in tilesets 0 or 7 (used for diagonal pipes). 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.
$00E91F	12 bytes	Mario physics	Table of Y speeds that conveyors push Mario with. Each 16 bit value refers to one type of conveyor: - $0000: flat right. - $0000: flat left. - $FFFF: up right. - $0001: down right. - $FFFF: up left. - $0001: down left.
$00EA08	3 bytes	ASM	Change [20 29 F6] to [EA EA EA] (JSR $F629 to NOP NOP NOP) to prevent the player from getting killed when stuck in a block, such as a cement block. Instead, they will get thrown downwards.
$00EA82	1 byte	Mario physics	[10] Change to 80 to disable spin jumping from water
$00EA8E	1 byte	Sound effect	Mario spin-jump from water sound effect.
$00EA9C	1 byte	Mario tilemap	Mario's pose as he comes out of the water.
$00EAA0	1 byte	Mario physics	How high Mario can jump out of the water.
$00EAC1	26 bytes	Objects	Table of which slope tiles on Map16 page 1 are in water.
$00EB79	2 bytes	ASM	Change to A9 00 to make Super/Fire/Cape Mario have a 16x16 interaction field (like Small Mario) or change it to A9 01 to have a 16x32 interaction field (like big Mario) (in conjunction with addresses $01B4C0 and $03B67C)
$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.
$00EC0D	1 byte	Controller	What button to press to activate a door. Format of $7E0015. (byetUDLR)
$00EC11	1 byte	Sound effect	Entering Door Sound Effect.
$00EC64	11 bytes	Mario physics	Code that makes munchers and spikes not to hurt the player if the player's hitbox on the left or right side of the block is next to them. This essentially reduce the hitbox the block by 1 pixel so that it requires the player to move into them to trigger damage.	Code
$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.
$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. Block order is as follows: 00-1C: Tiles 111-12D 1D-20: Tiles 021-024 21: Broken turnblock 22: Green ! block 23: Yellow ! block
$00F080	36 bytes	Misc.	Table for several Map16 blocks that handles which powerup is spawned out of the block when it's hit (see here for more details). Block order is the same as $00F05C.
$00F0A4	36 bytes	Misc.	Table for several Map16 blocks that handles from which sides the block is activated, in ----btrl format. - = unused, b = bottom, t = top, r = right, l = left Block order is the same as $00F05C.
$00F0C8	36 bytes	Objects	Table for several Map16 blocks that handles which tiles to generate (the value stored to $9C) when the block is hit. Block order is the same as $00F05C.
$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
