I am new to the customizing side of PSPs, I have a PSP 1001, with firmware 3.30 (Oficial) and I would like to customize it so that I can get emulaters and so on to run since I am a fan of the old school games. As it stands right now I am totally confused with upgrading/ downgrading and where to get what. HELLLLLLLLLLLLLLLLLLLLLLLLLLLP!!!!!!!!!!!!!!!!!!!! !! PLZZZZZZZZZZZZZZZZ!!!!!!
