Tip: Layer 3 backgrounds and tides disappear when you hit a message box, so plan your level around that. For example, you can add a sublevel without layer 3 at the start/midpoint, and include your message there.Not logged in.

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.

- 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.

$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.

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.

$009D73 1 byte Misc. Second tile of the *96 icon.

$009E25 1 byte Misc. Amount of lives to start with.

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.

$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).

$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.

$00A320 - Mario/Luigi Palette - Amount of colours * 2
$00A390 1 byte ASM [C2] Change to 60 to disable all animations in levels. This includes colour 64.
