Since lower firmware PSPs are difficult to find. I guess my only other option is to buy a refurbished chip-modded PSP I saw online. My question is if I do get this pre-modded console can I still play ripped backup umd games and downloaded isos without doing anything else (modds/flahsing/etc)? Would I need to just place these isos,csos into the memeory stick root directory and play away? Or will i need to do anything else. The chip that I am looking at is the Undiluted Platinum Mod chip.
