Yeah I was doing porting for gmod, till I got banned from facepunch. Then I got into file I/O and have done a few program on xentax to take 3D models from games into 3DSmax and back.
I'm trying to get the courage to open a FFX model file in a hex editor. Because I remember yaz0r worked on the ps2 version and he said it had used heavy compression. :/
But it would soo incredible if FFX was fully customizable, sound, textures, models, etc just amazing!
