I made this about a month ago, and only posted it on XboxMB and TTG, so I decided to post it on here as well. Basically it allows you to edit your campaign progress, set the difficulty at which you beat the missions, unlock skulls, change your armor, change your emblem, and unlock achievements.

Yeah, but there is a checksum. I have looked into it, but I can't figure it out, besides I don't know much about fixing checksums. It looks like it's SHA-1, but idk for sure.

Yeah like I said idk much about checksums. I just saw it was 20 bytes and assumed.

Edit: What other 20 byte hashes are there?
