I have a psp 1000 model with OFW 6.20. I've never tried hacking it at all. I'd just like to enable use of GBA and PSX emulators in the simplest way possible. I've read several of the stickies and other topics relating to this and I can't figure out if I need custom firmware or not, and which one I should get if necessary. Any help you can give is much appreciated.
