its pretty much the exact same thing but there are differences since it's on 360. They've apparently even fixed it at the end so you can actually reach and unlock this one secret area. You needed a key to get in there in the 64 version but Rare never bothered with it or something. Very mysterious if you ask me ... so anyways that's probably the BIGGEST difference. The lil differences have to do with the whole 360 environment (Bottles telling you to press X instead of B and etc) and then when Bottles informs you that you've unlocked a Gamer Picture lol ...
