I am an absolute novice, so please be patient! I bought a PSP in Korea and I'm not sure what the firmware is. The dude who sold it to me didn't speak much English but he sold me a PSP with games that run from the memory stick. On the system information it says 3.30EAR+, so I don't know what he did with the machine. I just want to know what I've purchased, so I can get into modding. Is the 3.30EAR+ firmware he installed, or did he leave the firmware intact? Any ideas?
