Having just got my PSP to run Prometheus, I'm looking at getting a decent size memory card. I have a 1GB card at the moment, which is holding 3 PS1 games and about 40 GBA games, but I'd like a bigger card. Preferably 8GB+. So here are my questions. - Anyone know where I can get one at a decent (read: cheap) price? - I've been cruising the net and some of them have 'mark 2' on them. What does that mean? Does it make any difference? - Some on eBay claim they're specially for the PSP Slim. Does it use a different size card to my Phat model? - Why aren't they sold on ShopTemp?
