|SMW Memory Map|
|$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.|
|$00BA9C||32 bytes||Pointer||The high byte of a series of Map16 data pointers in horizontal levels. The low bytes are at $00BA60, 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.|
|$00BABC||28 bytes||Pointer||The high byte of a series of Map16 data pointers in vertical levels. The high bytes are at $00BA80, and the bank byte is either $7E or $7F. These are indexed by screen number; each byte in this table and the other corresponds to the start of a particular screen's Map16 data (or chunk of 0x200 bytes, which means that these are all simply multiples of 2 plus #$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  to , the keyhole will activate the normal exit.|
|$00C526||1 byte||Music||Music played when you have completed the Bonus Game.|

|$00C576||1 byte||Debug||DEBUG: Powerup select (F0 = enable)|
|$00C599||28 bytes||Pointer||Pointer to Mario's animation routines. ($7E0071)|
|$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.|
|$00C92C||2 bytes||Misc.||[F0 3D] Change to [EA EA] to prevent Mario walking after touching goal spheres or the goal tape.|

|$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 or 02. Leaving it as 00 will cause no exit to be activated at all, and values 03-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)|

|$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)|

|$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  to  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.

|$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.

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.

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.
