okay so my friend emblemcrossing recently told me about a really cool app you can get on your Nintendo 3DS/2DS to transfer save data on a physical copy of a game to a digital copy of a game.
simply search in the nintendo eshop for Save Data Transfer Tool. it was made by nintendo so it’s totally safe and it downloads in a few seconds.
as soon as you load it up it has very simple step by step instructions and all you have to do is put in you hard copy of the game and it will transfer that save file to a digital copy you have downloaded.
this will delete your save file on your hard copy and replace the one on your digital copy if you have one.
I’m not sure how many people will need this or find it useful, but I figured it might help someone.
this will transfer the save data from a bricked hard copy to a digital copy as long as the cartridge is still readable.
