The Save Data Transfer Tool for the Nintendo 3DS is out now on the 3DS eShop. It’s used to transfer save data from a retail 3DS Game Card to a downloadable version of the same game from the eShop. Mario Kart 7 is the type of game I can play for hours and I wanted to have that with me all the time, so I went ahead and downloaded it. I decided to put together a video showing how to transfer my save data from the 3DS cartridge to the downloaded version. It’s pretty quick and easy, as you can see. Take a look!
