I did a search through google as well as on this site and couldn't find an answer that ended up helping me out. I have a slim PSP running cfw 5.00 m33-6 and I was trying to run GPSP, I've tried both the latest UO Kai build as well as GPSP-J. I have used two different bios files, just to try to see if that was the issue. Whenever I try to load up any game the screen goes white and the PSP freezes (and often shuts off). I was wondering what steps I could take to fix it. This is my first foray into using emulators on a handheld--so please pardon my ignorance!
