Ah, I guess that's why I didn't get FreeSCI to work. Still, I got ScummVM working perfectly, except from Broken Sword 1. I assume it's because of the screenmode, because it definately looks like that.
About the SD cards, it looks like it's pointless to buy a mini-SD card until I have taken full advantage of the ordinary SD card slot. I have two slots on mine, one takes the SD card while the other takes the mini-SD card. mini-SD cards seem rather expensive, so I will rather buy a 1gb SD card before spending money on the mini-SDs. For now, I'm quite satisfied with 512mb.
