OK GUYS. newb here. making a new thread. please correct me if im wrong. but in order to play PSP ISOS on a 2.71 do i have to do the following: downgrade to 1.5 via devhook (or just downgrade 1.5 at least) and then load devhook version 0.4-something to play the ISO? just had to make sure before i went ahead and downloaded a bunch of stuff and started doing this.
