I just found a psp 2000 with firmware 6.60 for 8 bucks at a garage sale. It has a 32GB card in it. Just wondering what is the latest custom firmware? checking youtube and they have tutorials for PRO-B10. Is that it? This will let me play backup iso's of games right? I gotta find out how to play some emulators to. It will let me right. Back in the day you needed a pandora battery. It seems like you don't need one anymore am I correct. I won't have problems with newer games like ps portable 2.
