ok so when i first got it set up it ran fine, and could play the games. but when i replaced it with the games i wanted, pokemon platinum started messing up and when i went to the games folder it would turn white. then i replaced it again, and now it's telling me it cant find the shell folder. i've tried replacing it, and also i tried re-formatting it but that didn't really work. could someone help me with this??? oh and do the games have to have the system file with it? or can it just be the .nds file?
