My screens been broken for a while and I've been just using my PSP for music. I just got one and I'm still at 5.00 m33-6. I'm reading that some people are still on that and some are at 5.50 hen which may cause problems with some games. How many games require 5.50? Should I really update or am I good here for a while? Are there plugins or something that I should add to 5.00 m33-6.
