OK everyone, I just have a few questions regarding PSP 1.5 devhook 3.01 and that whole 3.03 OE or w/e it's called. If I were to upgrade to 3.03 OE, what are the advantages, besides being able to play PSX games. Can I still play PSP ISOs just as easily? In addition, please post directions on how to upgrade from 1.5 to 3.03 OE. Will I have to do monthly updates for 3.03 OE? Or is it fine as it is. Thanks!
