I have a few questions regarding this hack. I am using a New 3DS XL btw.
1. Can I back-up saves and replace saves from games like VVVVV and Citizens of Earth?
1.5 can I edit my save from Pokémon Picross?(I hate the paywall)
2. Will emulators work?
3. Can I edit my play coin count and that kind of fun stuff?
All this will do is get you to homebrew, but there's apps for all that other stuff once you're there.
