Halo 3 GPD Editor

[Experiment5X]

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.




If you find any bugs, please post them.

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.

i was just wondering. since i just picked up the limited edition at best buy for 49.99.

Nope, Definitely not a SHA-1, But i'm sure that there was a check fixer for the game, Unless it was just for the personalfile (campaign checkpoints) I can't remember

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?

Edit: What other 20 byte hashes are there?

the only two algorithms i know with 20 bytes are
SHA-1
RIPEMD-160

[Buddah]

HMAC -SHA1
SHA1-cng
HMAC Ripe MD
