Hello! So my friend recentre got a PSP 1003 (which I'm guessing it's a PSP 1000 in england) and needs to know this one question: "Do the UMD game's work without a Memory Stick PRO Duo Card? " He means if the games will save. I would answer this because I had the same type of model since I was 4 (in 2005...don't ask me.) But I always had one in there and my friend has had it since last year and can't find it..So do the game's work without a memory stick?
