I just got a pre-modded PSP off a friend but I know very little about PSP modding. It has FW 4.01 M33, a GBA emulator, and Megaman X6 (not sure if actually bought or not) on it. What can/can't I do on it? What do I need to get it to run the most recent games/homebrew apps. Also I do not have a Pandora Battery. All help is appreciated.
