| - | ======== Model Images ======== | ||
| - | Banjo-Tooie uses a file-system in which most resources are packed into image files 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. | ||
