So I updated to 6.60 proc2 as recommended, and everything works great. I'm new to all this but the only homebrew/mod stuff I installed was the CWCHEAT files, and it's in the right location, and it's set for PSP (with the line for PSP go removed) When I get to a game, I wait till it's at a normal point in the game (non cutscene) and holding select brings up the cheat list for the game and it looks fine. I've tried turning on ONE cheat, for a few different games, and the screen freezes as soon as I click the activate button, and after about 30-45 seconds, the PSP automatically does a self shutdown. So what am I doing wrong? Running a somewhat recent cheat file from a few months ago on a PSP 2000 btw. Thanks!
