I have a 2.71 Version PSP. I see there are so many homebrews out for 1.5, and others, but honestly what should I do? Should I downgrade to 1.5, or should I uprade to a higher version? Or is there some emulators and homebrew that can run on 2.71? I would like to get a SNES emulator, and maybe a PS1 emulator. any advice from some of you pros would be awsome. thanks!
