I've had my PSP for some years and wasn't using it for a while. Recently I picked it up again to play FF Type-0 only to find out that I needed to update the FW. Before, I had "PRO Nightly Build" on the version so I don't know which one I had. I updated it to 6.60 Pro C2 and found out that I cannot get it to run permanently where I previously had it. So the question is on my PSP model on this firmware, is not possible to make the hack permanent?
