I use the scan disk micro sd also and I find it works best if you don't load your games into a single games folder. I have each game loaded into it's own folder and then load each individual game folder directly onto the sd card. That's what works for me anyway.

I wonder if anyone knows what I'm doing wrong when it comes to loading snes games and emulators though. I loaded the emulator files onto my sd card and I'm told that I need a folder called SNES to load my .smc games into. I've done exactly that and yet when I turn on my ds, I get MENU? in red letters. Are emulators not compatible with dstt cards?
