Marvel VS Capcom 2 problems
 

Is there any reason why a slimline PS2 would not be able to play MVC2? The game loads up to the menu screen but selecting any option doesn't get you anywhere. I've heard that there were problems with blue back discs for the first generation PS2 but I'm pretty sure that doesn't apply here. Thanks for any help that can be provided.

Certain PS2 consoles have trouble reading CD-R (or blue) discs. If it's a legit copy of the game, the fault's related to the PS2, not the game. However I'd just buy a Dreamcast and burn it if you're really interested, since the PS2 version isn't arcade perfect.

I don't know about slimlines but it sounds like they haven't bothered to fix whatever the problem was originating with CD-R based games.
