No, don't ungrade to 3.XX!! it causes your PSP to lose the ability to be downgraded until further notice.
I'd rather have a 3.X OE PSP than a 3.XX
Thank Dax!
Plus, it comes with the famed PopStation PSX Emulator!
I've had first hand use with all of these, the only way to brick your PSP is to be an idiot and not follow the instructions carefully.
PopS is a full speed, powerful emulator, especially for the PSP. The graphics are running at the PSP's full potential, the input is perfect, it's amazing!
Too bad my motherboard's cracked.
