I've did some research on this website the last couple of days, and have learned that it's probably best to install 6.60 CFW PRO-C and 6.60 CFW LME v1.8 on it, dual boot. Today I bought a PSP Go White for €50, because I wan't to play Metal Gear Solid Peace Walker.
Im am fairly new to the homebrew scene, I've had an old psp a long time ago and once installed CFW on it to be able to play Metal Gear Solid on it, but for the rest I have no experience with it.
