I have a PSP that uses 3.30 OE-A and I was curious as to which custom firmware would be the best to update to. I want to play Dissidia, but I'm unsure on if my PSP's current firmware could actually play it (I just bought a new memory card to put it on, but I might be going to another store and I wanted to see if they were cheaper there before I opened it up). Is there any current firmware that can play most of the popular games?
