This seems like it is a newbie question to me but I searched throught the post and could not find the answer. So I have a M3 Simply, now I bought a game(Mario Kart) how do I get that game off the origional card and onto my micro card to put into my M3?
You can't. Unfortunetly it is not (yet) possible to backup a game using a slot-1 device, you either need to buy a slot-2 device if you want to backup yor own games, or just download a backup from the net.
