Extreme-G's level GFX commands use textures from three bank types.
This bank type contains CI8/CI4 textures that are unique to each level. Each bank of this type consists of two files referred to by the level header structures. The first file contains a table of texture meta data structures and the second file simply contains the texture data.
|00||8-bit texture width|
|01||8-bit texture height|
|02||8-bit format ID (01 = CI8, 02 = CI4)|
|04||32-bit offset of a texture's color index data|
|08||32-bit offset of a texture's palette data|
Used by GFX command 02: "level_texture".
This bank type contains CI8 textures that are shared between all levels. The global texture bank is stored LZHUF-compressed at 000C3400 in ROM.
|00||32-bit offset pointing to a single palette at the end of the bank|
|04||4 padding bytes|
|08||Texture meta data structure table|
|…||Texture color index data|
|…||0x200 byte texture palette|
|00||32-bit offset of a texture's color index data|
|04||16-bit texture width|
|06||16-bit texture height|
Used by GFX command 0C: "global_texture".
