Okay, so...I used to run 3.71 m33-2, if that's any clue as to how long it's been since I've messed with this stuff. I have a Pandora battery if needed. My PSP somehow updated itself to the 5.55 version of the official firmware, possibly because a while ago it had access to a wifi network for the first time ever and did it automatically? I discovered this when I went to fire up one of my PSX EBOOTs and got a "copyright protection is invalid". I just wanna get back to a point where I can play my PSX games on it, but I'm so out of touch with the modding community I have no idea where to start, what version of which CFW I need, where to get it, how to install it...can anyone point me down the right path, give me a hint as to where to get started?
