The VG Resource

So. I may sound dumb or something. But for a bit ive been trying to rip models from a GC bratz game
More specifically "Bratz: Forever Diamondz" Which I used QuickBMS as it has a script to extract Blitz games GCP files (which this is a blitz game and uses GCP)
doing that and getting the model files they are just generic files
I was wondering if anyone could help? Like I said though, I may sound dumb and may not be using it right or I should use a different program.

So there was a Bratz_rev Script for the 2 wii games Files. But those extracted the same with the files with no format.
It would be cool if i could look through the files properly. As far as i know no one has tried to mod or look into the game and find beta stuff.
