Although Nintendo has embraced selling all of its current and future first-party titles digitally, no doubt many of you have plenty of older content in cart form. But what do you do with your save files on your cart if you re-purchase a game in digital form? In the past, you couldn't do anything. But overnight, Nintendo announced a 3DS Save Data Transfer Tool, which will allow you to move save content from a cart to its digital counterpart.

The bad news? This is currently only confirmed for Japan, with a release targeted for this March. We don't know too much beyond that, such as how the tool precisely functions, and have reached out to Nintendo of America to see if and when we might expect the application to be released.
