I used my N3ds to play dlc and game cia downloads using gateway and emunand. My brother has always updated his 3ds so he never really gets to enjoy these things. Is there a way I can back up my emunand and sd card contents, then do the sd card transfer to his 3ds and him be able to access what I've installed through cia ? Or does it not work like that at all ? Sorry if this has been asked before, I just don't know what I would search exactly to find the answer to this.
