The 360 game i'm using is Unreal Tournament 3 (2007)
The 360 version uses custom XMA, where the PS3 version uses Atrac3 as MSF, and Windows use OGG.
It would be LZX, ZLIB, or LZO. Or else, it is decrypted or encrypted.
When using UModel, it crashes.
I'm trying to get some game textures, model assets, and sounds.
The issue
