I checked the Playstation Store and it doesn't indicate that they are only for the PS3 version. Since the PS2 version is compatible with the PS3 that's what I got since the PS3 version was being released later than the PS2 version.

The PS3 would not shut down using the controller button. I would press it and hold it like you're supposed to do and nothing would happen. That is why I used the back switch.

Can you give me any links to PS3 overheating issues? Thanks for the help.

I read something that PS3 can access Xbox Live and download 140 songs for the game. If that is true, how do I do that?
