Hey guys. Just found my old psp in my closet and thought I would mod it to play some emulators and what not. Now im not asking about emulations and where to get roms as I know that stuff. The thing I need to know is how to mod the firmware to a customized version. The psp is a silver 2001 slim model. THe current firmware is 5.55 (official sony) and the serial is HU4367540. Thanks in advance guys
