Rollcage/Rollcage Stage II

Hi,
Last month I came across the decompression algorithm for the Rollcage Archive file on the wiki. (LINK) I tried implementing it, fixed a bug or two, and added the results of the subsequent research on the texture/model files.

Granted - a lot of it won't make sense unless you've got sample data to work through - but I have the feeling though, that I'm murdering the style-guide! I tried to follow the formatting and style already there, but is there a standard for this that I could copy from? Should I go ahead and style it till it looks good to my eyes? Any feedback would be useful.

I probably should have registered earlier, since now I have too many questions :-)
  • From what I've seen, the data formats are the same for Rollcage 1 + 2. How best to handle that? Redirect? Rename? Add a note?
  • The model and texture files have their own format -- should they be on a separate page each?
  • I wrote some code to handle the extraction - first in C++, then Java. Is that of interest to anyone?
Progress-wise, we've identified the car + track models and extracted the textures. For the cars, we've found the texture coords and identified vertex indices in what seem to be face-definitions, but the normals and vertices themselves are still unknown. The track models are baffling. A lot of the early leg-work is already done, but I'm a n00b at this and I think that perhaps with a little experienced assistance we could nail this format quickly.
