Hello!
I own an Animal New Leaf 3DS XL(the limited edition bundle). The bundle comes with a 4GB SD card, but I'd like to upgrade to an SD card that can hold more games(probably 16GB), since I will be getting digital copies of games.
However, I've never done any data transfer on a 3DS before, so I'm worried that I might do something wrongly and somehow destroy or delete my existing ACNL save data(the game is pre-downloaded on the sd card) >< Help will be greatly appreciated. Thank you!
