I have been thinking of trying to do this because ever since I got the Tomodachi collection (ds version) onto my modded 3ds xl, the Tomodachi collection had a system in the town hall where you can get the Miis from the Wii to the ds and I wanted to try it out. But I'm not sure if it's possible because, in the Tomodachi collection from the ds, it doesn't have a button on the bottom of the selection where you could transfer your miis from the mii maker, it only has the feature to get miis from the Wii (not the Wii u). So yeah, I don't know if it is possible. Help?
