I've been looking at the converters that you put your Micro SD card into, and it makes it the size of a Memory Stick Pro Duo. It's because I have a Micro SD HC 8GB card already so I thought i may as well not waste loads of cash on an 8GB Pro Duo when I can spend maybe £5 on a converter. What i was wondering is if it'll work in a PSP, for gamesaves, as I doubt the Micro SD is MagicGate compatible.
