all games implement a sha1, since thats what the hashes on the whole container are. maybe thats what you are looking at. i always felt it was a sha1 with a salt of some sort.

I think the checksum is based on a few things from the gamer profile.
But i don't know.
If you mod the game with horizon, it requires the profile.
More i can't say.
Good luck

Yeah, after tracing through a bit more it does look like at least a few places that call the SHA-1 functions are related to scripting or engine related stuff. So I probably got my hopes up for nothing -_-
And I haven't had any luck disassembling Horizon as an alternate way of finding how it's done, either. Short of getting a Horizon dev to divulge their secrets, I don't see an easy way of figuring this out D:
Edit: Another way might be to trace through the sub that saves PlayerStorage.dat - sub_82989AF8.
