So I just got a cheap "phat" psp with custom firmware. I have firmware "3.80 M33-5". So here are my questions about this, since I really don't know about this kind of thing and don't want to screw anything up. What is the best firmware to have? I noticed that some ps1 games won't run on what I have. (Ehrgeiz for example). How would I change my firmware to another version? I downloaded some preconverted ps1 games to play, but I noticed that multi disk games like FF7 and Chrono Cross have just one PBP file. How would I play the different disks? That's all I can think of for now.
