I'm having problems with my psp, specifically with this game. Sometimes, usually when I save, it randomly turns off. I'm doing alcatraz in classic mode and whenever I do switchback manuals down the ledge, my psp freezes and turns off when i finish the second one. Anybody know what to do?

I had that same problem, except it was any time i tried to load the suburbs. My best tip is to try not to do said manual.
