Banjo-Kazooie 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.

*Geo Types: 0000=normal, 0002= Trilinear MipMapping (RGBA16), 0004=Env mapping, 0006=?

*Types: 01=CI4, 02=CI8, 04=RGBA16, 08=RGBA32, 0x10=IA8,

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

Example: 00 00 06 00 00 01 00 00 40 40 00 00 00 00 00 00

This will load a CI4 64x64 texture from segmented address 0x600.

Each 16 byte line of the Vertex Setup following the Start denotes where a vertex is stored in 3D space, from where in 2D space its UVs begin being mapped, and which color and opacity alpha values will be applied to these vertices.

It is stored like this: [xx xx yy yy zz zz 00 00 uu uu vv vv rr gg bb aa]

*Please note that s16 refers to 'signed short'; a value which may be positive or negative and takes 16 bits of space. Positive signed values range from 0x0000 to 0x7FFF, negative signed values range from 0xFFFF to 0x8000. Whereas u8 refers to an 'unsigned byte' value that may only be a positive integer from 0x00 to 0xFF.

Example: 0014 0062 FFE7 0000 FFE0 0014 9292 92FF

A vertex will be drawn at position (20, 98, -25). UV mapping will begin at -20 coordinates in the U axis and 20 coordinates in the V axis. This vertex will feature a color of #929292 with full opacity alpha of 0xFF or 255.

The Effects Setup for Level and Actor bins functions very similar in nature to that of the Effects Setup used in Banjo-Tooie only with fewer effects to use. Effects types only appear to go up to 10 types with several unknowns currently. Level models can have texture scroll, though actors and objects do not appear to have the same luxury. Some actors like Teehee & Twinklies have effects. There may be more at play that determines how effects are activated.

Effect IDs are

Data Start = 100*Type + Param  (decimal)

where param is used to control the speed or amplitude of the effect. For Data Start in the table, param used is 0 and can range from 0-63. Type is taken from

Example (GV Model A):

0003 0078 006A 0010 0011 0012 0013 0014 ... 0605 00AA 0015 06AC ... 06C0 0190 0007 0182 ... 018A 0000 0000 0000

Loads 3 effects, the first being 78 (Medium Scroll) with the full vertex count of the effect being 106 (6A) vertices. Verts in the bin that scroll range from vertex lines 16 (0010) to 122 (0605). The second effect in the bin is effect 00AA (fast scroll) with a 21 (15) vertex count ranging from vertex lines 1708 (06AC) to 1729 (06C0). The third effect in the bin is effect 0190 (??) with a 7 vertex count ranging from vertices 386 (0182) to 393 (018A). There is a 4 or 6 byte padding buffer at the end of most effects setups.

If the model's animated_textures_offset is non-zero, the animated texture list is an array of 4 of the following struct:

Note only the 1st texture in the model can be animated, however it can be animated with 4 different framecounts/framerates. —
