So I have a gateway 3ds, no issues here. But my GF wanted to play some of my games so it occured to me that maybe I could buy her a 32gb SD card, use my gateway to setup her 3DS by installing the BigDevMenu cia files(whatever I need to install and uninstall cia without a gateway card). And proceed to get CIA games on the 32 GB. Is this viable? I play my games through the gateway paired with a microsd, but could she roll with using just cia? any concerns, I heard a lot of odd things about cia files(like visiting a menu deletes stuff or something).
