I just got a PSvita recently, and I also got a game with it (FFX-X2). Upon loading the game it says that I need a card for it, I understand that it can't save without one. My question is, if this requires a card; would I not also have to have a card for the Sd2vita that I just bought and is coming in the mail? I know it needs an SD, I just need to know if I also have to buy a 4 gig mem card as well
