Ok, it has been years since I even touched my psp. I know at one point I had CFW on it, but somehow it is gone. The system is running 1.5 right now but I can't play anything or update anything. It will turn on and go to the XMB but that is about it. What do I need to do to make it a playable system? Also, what is the newest software and such? It is a psp 1000.
