Having this same problem, even though I ripped straight from my legit copy. I believe it's because we have to dump using the Redump method, which requires a specific disc drive. I'm so sorry but I'm not paying for that :( I rlly wanna contribute my games though
" I'm an evil scientist, what do you expect? This isn't a game."
I have tried to upload some of the games from my Xbox 360 library (specifically "Epic Mickey 2" and "Lego Harry Potter Years 1-4" and every time it's done uploading it says it has the wrong hash. If I'm doing something wrong please help me.
