so I've been recently contemplating buying a SC DSTwo and I was looking for info on what microsd to purchase. My main concern is of course any possible frame rate issues. I would like to know if better read speeds on the sdcard equates to better performance, faster saving, etc. These are the cards I'm considering atm: Sandisk Extreme Pro 8 GB (95 MB/s Read) Sandisk Extreme 16 GB (80 MB/s Read) Sandisk Ultra 16 GB (30 MB/s Read) Another question I had was if I could put multiple ROMs on the same microsd and play them on the 3DS. Anyone care to enlighten me?
