I ordered a new 3ds from EU (the smaller one) to use in the USA. I also plan on buying a NA 3ds xl so I can continue to use all my eShop software. I am not sure if sky3ds or gateway 3ds are the answer but I am open to buying them. My goal is to be able to play a game like majoras mask on both consoles. While this is possible, is it possible to have the save data work on both the EU 3ds and the NA 3ds?
