My friend gave me a PSP 1000 recently with 5.55 firmware and It does not have a memory card I have a few questions about hacking and putting a CFW on the device. 1. Which firmware should I have before installing a CFW for best results?( My main goal is to play ISO/CSO game files on the PSP) 2. Which memory stick/card do you guys recommend? 3. Can I insert the memory stick into the computer directly? If not, what is the process for copying info. into the PSP? 4. Are there any other things/tips I should know? Thanks for your replies guys! Stay classy.
