Does anyone know if there's a way to access two-player mode with only one player/ one PSP? I'm not looking to play a full two-player match on a single PSP, mind. I just want a "proper" VS match with the second player standing around as an uncontrolled training dummy, like is possible in every other MK game.

I bought the PSP specifically for this game; no way in hell I'm buying a second one just so I can practice my finishing moves. Any help would be greatly appreciated!
