woah boy, this guide is woefully outdated. The game has been patched a long time ago, and while the game is still buggy, the achivements are not so this guide is in need of revision. I just 1000'ed this the other day and sadly, x360a wasn't helpful. I don't care about credit, I just want a good guide to reference. Here are my corrections for the outdated achivements:
its kinda sad I had to refer to x360a's sister site PS3trophies on how to get all the achivements for a 360 game. The only one I'm not certain on is the Who Wants My Autograph? I'm not sure if your A ranking gets canceled out if you replay a stage and get a worse grade.
