So I recently got my friend psp. I love it! I wanted to get an emulator for gba on it and it worked unfortunately i updated the system and now it has the 6.60 PRO-C fix3 firmware. because of that I can't use emulators anymore. I think i have to get a custom firmware but i'm not sure how. I have a hard time using things on the computer because I usually don't have one available. All I want to do is play gba while still having access to the psn store. if i can do that please help! if not.....well help me get rid of the firmware so i can play gba! i'm having quite some troubles T^T
