I currently have a PSP-3000 running CFW 6.20 Pro-B10. I decided to purchase Legend of the Dragoon from the PSN store, but I found that I couldn't install it because (I suspect) it runs a check for 6.60 (or whatever the latest PSP firmware is). I have the permanent CFW patch installed at the moment, but I was wondering whether I would have to upgrade to 6.60 PRO & how to go about it. I'm scrounging around looking for the USB cord, (too many cords!).
