For mostly educational purposes, I'm working on a program that will read maps from the Goldeneye ROM and render them, with textures and all. If I make it that far, I may turn it into something more. I've made a little bit of progress using info that I've scrounged for in these forums.

It appears that each room in a map has 3 main blocks of data: vertex data, primary mapping, and secondary mapping. I have the vertex format figured out, but I'm stuck on the primary mapping data. My only guess is that it's made up of machine code, which complicates things quite a bit for me. Are these blocks executable code, or are they something else? Any help is appreciated.

Edit: Here's an example of the decompressed data:
