How Do You Run A Game With Modified Content?
Posted 27 June 2008 - 05:32 PM
afaik, all content on an xbox 360 game is signed, just like the executable, if you change one little thing, you break the signature, the game/content is invalid and the game will not run.
On the wii, the same principle applied but they've found bugs and stuff so you can sign your own content and that's it.
But for the 360, I've seen custom Guitar Hero games, custom PES games and... I always wondered what was done to run this.

The firmware hack lets you run a modified ISO in principle. Signing/hashing is applied to individual files in the ISO, not to the whole image. You can't modify any file which is signed or hashed at all - this is at minimum all .xex executables. Files which aren't signed or hashed can be modified just fine. Which files are which is entirely dependent on the game - some games may have many modifiable files, some games may have signatures on every single last file on the disc.

To figure out if a file is signed scroll down to the end and check if there is a hash...(CRC)
