I'm considering buying a PSP slim (And hacking it, of course), and I was wondering which memory card is most suted to being used for, ahem, Backed up PSP and PSX games and homebrew in general. is speed an issue? how big are the games? will 2 gigs do, or will 4, 8 or even 16 gigabytes be necessary? Also, how hard is it really to make a pandora's battery and have the battery work again? Would I be better off buying a pre made pandora's battery? Also, if you send me links to sites to order from, take note of my location first. I hate to ask so many questions at once, so thanks to those who answer.
