So there's this one game i'd like to open up and mod, but the models are in SCO format.

What I can tell you, however, is this;
When opened in notepad, the files usually have this structure:

(some more number sequences here)
The textures are, usually, 512x512 24 bit Bitmaps.
I have uploaded here a sample of a model folder along with it's textures and whatnot.
