I think it's an EZ5. It says EZV on the front, but I haven't been bold enough to check the circuitry yet. I didn't purchase it myself, it actually came with the Lite when my friend gave me his old one; I just happened to have an R4 card as well. How do you back up the NOR save then? I have two 32 GB games, but I don't want to play the other until I'm certain my Mother 3 save is backed up.
