Save Data Transfer Tool

This page is rather stubbly and could use some expansion.
Are you a bad enough dude to rescue this article?

Save Data Transfer Tool is a 3DS app that lets you transfer save data from a 3DS game card to a digital version of the same game, but not the other way around, presumably because Nintendo wanted to encourage people to buy (inexplicably more expensive) digital versions of the games. For some reason, it also requires an internet connection.

All in all, a better option is to use a homebrew tool like Checkpoint.

Internal Project Name#

The app is internally known as Fairy. The sound archive bears the name and it can be seen in various strings within code.bin, including some debug leftovers.
