I've been out of the PSP scene for a couple years now, so I thought I would ask before just jumping in and updating to the latest CFW. I'm on 5.50 Prom-4(old fat PSP). Should I update or will most things play on this firmware? And if I should update, according to this thread it's showing 6.20 Pro (permanent) and 6.60 Pro (temporary). Are these indeed the latest? I never even knew that there was a permanent and temporary, so that shows you how long I haven't been involved. Couple more questions. If I should update can I update straight from 5.50 Prom-4 to the latest, or do I have to update to an early version first and then to the latest? And finally, I'm guessing 6.20 Pro (permanent) is what I should update to and not the temporary one? I don't want to have to keep reinstalling anything so I'm guessing permanent is what I should go for... Thank you for any help.
