a program I found made by Anthony and Quickkill0.
I saw this being used to edit GoW2 Coalesced_INT.bin files.
This program will open GoW3 Coalesced_INT.bin and allow you to
edit them easily. I used it to make ISO mods. I do not have a JTAG
but I assume it works for that as well. i also included WinMD5 so
make corrections to you Xbox360TOC files.
So use those to make changes to GoW3 and then use
Xbox Image Browser 2.9 to replace the files in the ISO
run abgx and burn.
There is TONS of things you can change in the game
