Well I will be getting a PSP 3000 for my birthday. May be 9 years late to the game but my local Target has a bunch in stock for $99 so my girlfriend grabbed one for me. At that price I could not pass on the console mostly for a few JRPG's I want to play. I learned I will need to get a memory card in order to save. Thought this would be an easy google search, even expected to find a page on sony's site listing all compatible models but I have been overloaded with information and can not get a clear answer. I see I can get a questionable microSD adapter and try my luck with those cards but for now want to ask about only officially supported Sony cards. What is the largest Sony branded card the PSP will support on official stock firmware? Better to go with Memory Stick PRO Duo OR a MSPD to M2 adapter with an M2 card from Sony?
