======== Model Data ========

Banjo-Tooie uses a file-system in which most resources are packed into file blocks throughout the ROM, and are unpacked into RAM when needed. Among these are the model files, each with their own syntax and load-lines. This page's purpose is to cover the syntax and properties of said model files.

===== Texture Setup =====
^ Offset from TexSetup Start ^ Value/Syntax ^ Description ^
| 0x00000000 | [<color darkred>aa aa aa aa</color>] | Amount of data in bytes to load (including command) |
| 0x00000004 | [<color darkgreen>bb bb</color> <color darkblue>cc</color> 00] | bb=Texture Count, cc=External Textures(01y 00n) |
| 0x00000008 | [<color darkred>dd dd dd dd</color>] | Texture[i] segment address from texture data start OR External Texture Index* |
| 0x0000000C | [<color purple>ee</color> <color darkgreen>ff</color> <color darkblue>xx</color> <color darkred>yy</color>] | Texture[i] <color purple>ee</color> = 0x80 for MIP Mapping (00 otherwise), <color darkgreen>ff</color> =type*, <color darkblue>xx</color><color darkred>yy</color>=Pixel Grid |
''*Types: 01=CI4, 02=CI8 04=RGBA16, 08=RGBA32, 0x10=IA8,''

<code>*External texture indices start at FileID 0x1EF6, 0 indexed.

Example: 00 00 13 28 80 04 20 20

External texture file ID= 1EF6+1328 = 321E
This will load an RGBA16 32x32 mipmapped texture from FileID 0x321E.</code>
