WRAM Map

Jump to bottom
Bruno Valadão Cunha edited this page Jul 13, 2024 · 18 revisions

The Super Nintendo Entertainment System has 128kb of system RAM (aka WRAM) that every game can access, spanning from $7E0000~$7FFFFF. This map explains what each address represents in Yoshi's Island standard gameplay gamemode $0F. In Yoshi's Island in particular, since it has the Super FX enhancement chip, much of the game's memory is stored in cartridge RAM instead. This is why there is so much free WRAM in this game. Nonetheless, there are still some pretty important pieces of data stored here.

$7E5D98 2 bytes Misc. Number of bytes Yoshi's in-between level egg inventory items take up (# of items * 2)
$7E5D9A 12 bytes Misc. Egg inventory items stored in between levels (not current eggs), 6 words, each one is a sprite ID
$7E5DA6 2048 bytes Misc. Cross sections: Full copy of cross section BG3 tile graphics, set only once upon loading cross section levels and then every frame stored to $706800.

Chomp Shark: BG3 tilemap animations (in what format?).

$7E71A6 1024 bytes Layer 1 Tilemap Overlap between $7E6DA6 and $7E75A6, both tilemaps are actually 2048 bytes and this acts as either one depending on when (free RAM if not using cross section BG3 header $0A)
$7E75A6 1024 bytes Layer 3 Tilemap BG3 tilemap mirror (VRAM $3400) used for cross sections (free RAM if not using cross section BG3 header $0A)
$7EB8E2 1822 bytes Empty Unused RAM, cleared (with $00) via DMA during reset as well as before and after Nintendo logo
$7EC000 16384 bytes ASM Copy of $00C000-$00FFFF (Code is never executed with the data bank as $00 for this range; it's always $7E)

$7F56DE 438 bytes Object Palette Blue channel of background gradient ($2132 COLDATA)
Covers entire sublevel (NOT just screen) from top to bottom, one byte per entry, representing every eighth X pixel row in sublevel
$7F5894 876 bytes Object Palette Green & Red channel of background gradient ($2132 COLDATA)
Covers entire sublevel (NOT just screen) from top to bottom, two bytes per entry, representing every eighth X pixel row in sublevel:
Byte 1: Green Channel
Byte 2: Red channel
$7F7E00 512 bytes Level Data All screen exit data for current level, in screen region order ($00-$7F), 4 bytes per exit:

LLLLLLLL XXXXXXXX YYYYYYYY EEEEEEEE
L = Destination Level (between 00 and DD)
X = Destination X-Coordinate
Y = Destination Y-Coordinate
E = Destination Entrance Type (this follows the same format as $7000AC, Yoshi state)
$7F8000 32768 bytes Layer 1 Tilemap Table that holds all foreground MAP16 tile data for the entire sublevel currently loaded. Split up by screen ID's then further into row-major tile #. Data is word-sized MAP16 indices.
