Okay so I got a PSP (Used). It's a Silver Slim with 3.71 M33-4 custom firmware.
When I first turn it on it's fine for a few seconds then the screen like... flickers or twitches and then it's all laggy and !@#$%. Any thing I try to load (The music part, settings, etc.) it just sits there and loads SLOWWWWLY.
What the hell is wrong?
