So I load up my iso of Crisis Core, which boots fine. I load my save, which works. I hold select for 3 seconds, enter CWCheat menu. Select cheats, enable cheats return to game and my game hangs and my PSP crashes. Why is this? I've spent the past 5 days searching google but I can't find anything that helps. Also, if it's useful to you, it's a PSP-2002 model with 5.00M33-6. Thanks.
