I intend to get a Psp slim for christmas (well ask for it anyways!) I bookmarked a few sites selling a Datel Battery for the Pandora Bootup. I'm curious about the memory stick. I own a DS with a 6GB Micro SD card, will that work for this? Besides the battery, a memory stick, and the system of course, is there anything else I need to buy to play iso's such as Jeanne D'Arc? Thanks ahead of time!
