Great! Thanks for the reply.Yup! This is the same for any other downloaded game, Pokémon or not.
What should I do if I want to clean my entire 3DS (a.k.a. uninstall and reinstall everything)? How can I keep my save file in this way?
Also (kind of a different question): How would I go about preinstalled games? Are they locked onto an SD card? I mean, if I have Mario Kart preinstalled and I would use a different SD card for my 3DS.... will the game be gone?
