6AB5B$0D:A95B34 bytesObjectsThe subroutine that enables most objects to go across screen boundaries in horizontal levels without glitching. (It doesn't work in vertical levels.) It also stores the value of A to [$6B],y. (Forgot to include that info before.)
6AAC3$0D:A8C3152 bytesObjectsMain creation code for the objects that are made up of only one Map16 tile and can be extended both horizontally and vertically, i.e., objects 01-0E and tileset-specific object 31 when it forms ice-blue turn blocks.

6A8D1$0D:A6D129 bytesObjectsMain creation code for extended objects 47 and 48, the normal door and P-switch-activated door.

This is also the routine that unused extended objects 98-FF point to (they just pull garbage tiles).
6A8CD$0D:A6CD4 bytesObjectsMap16 data for the door and P-switch-activated door. In order: Top tile of normal door, top tile of P-switch door, bottom tile of normal door, bottom tile of P-switch door.

6A8B1$0D:A6B19 bytesSubroutine (JSR)A routine that backs up the low and high bytes of the Map16 data pointers. It stores $6B and $6C in $04 and $05.
6A84D$0D:A64D5 bytesObjectsThe start of the routine for extended object 17, the green star block. It loads a hardcoded index to the table at $0DA548.
6A77B$0D:A57B210 bytesObjectsMain creation code for extended objects 10-40. (Extended object 17 uses a different pointer, but it jumps to the same routine.)
6A748$0D:A54851 bytesObjectsMap16 data for extended objects 10-40, low byte. They are in order of object number, but the 8th byte is unused (it would be used for object 17, but the final byte in the table is used instead). The high byte of the first 19 tiles is 00, while the high byte of the rest of the tiles is 01.

The YI submap starts at $0CFBDE (67DDE) and is a simple format: One row of tiles at the time, 16 bytes for one line.
Level numbers are a little trickier, though:
Level numbers aren't anywhere in the rom. The loading routine assigns them when it runs. If you remove or add a level tile, you'll shift all of the levels after it. And the order of the tiles in the other submaps is even weirder, but if you look at the OW as 16x16 blocks and ignore submap borders, it'll start making sense.

2BD39$05:BB39109 bytesSubroutine (JSx FIXME)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.
2BB99$05:B999416 bytesGraphicsFrame 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.

2BB7D$05:B97D15 bytesGraphicsTable 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.
2BB6B$05:B96B24 bytesGraphicsThis 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.
2BB3B$05:B93B48 bytesGraphicsDestination 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.)

059A5$00:D7A53 bytesMario physicsGravity. 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.
05918$00:D7181 byteMario physicsChange [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.
05917$00:D7171 byteASMChange [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.

0586F$00:D66F1 byteMario physicsChange 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.
0585E$00:D65E10 bytesASMMario jumping routine. (Sound effect + store to Mario Y speed.)
$00D65F (0585F) is the Sound effect for Mario jumping. (05861) is the bank for the sound effect. By default it uses $1DFA, but you can make it use $1DFC by changing (05861) to FC or $1DF9 by changing it to F9.
0584A$00:D64A1 byteMisc.Spin Jump Sound, uses bank 1DFC.
05845$00:D6451 byteASMChange 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.
05844$00:D6441 byteMario 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.

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.

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.

006D0$00:84D0258 bytesStripe ImageStripe 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.)
00493$00:82931 byteMisc.How many scanlines the status bar uses during a regular level.
00379$00:817944 bytesASMHandles transfers to and from the SPC700 (I/O). Changing all values to [EA] (NOP) or jumping over the code effectively mutes all sound.

0026B$00:806B14 bytesASMThis 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.
00252$00:805225 bytesASMThis is the main part of the SMW initialization routine. SPC engine upload, sample upload, OAM setup, windowing setup, and RAM clearing all happens here.
00227$00:802743 bytesASMThis 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.
00200$00:800039 bytesASMThis 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.
