This is the same idea for my gametype hacking topic:
transfer a profile from your xbox to pc
unzip it, and open up the file "blam.sav" in a hex editor.

i'm mainly looking to see how profiles/gametypes can be hacked, since those would work easily on unmodded xboxs. i want to see how far i can stretch my game without a mod chip.

there has to be something interesting you can change in that; the file's too long for nothing interesting to happen.
