Hi I have a question! I have an old nintendo 3DS and I want to get the new one. But I'm not sure if my save file is saved to the cartridge or saved to the 3ds. If I put the cartridge in a new 3ds will everything be the same? Thanks!
If you have a regular old game cartridge then you have nothing to worry about- your dream address code and friend code will change, though!
For people with the downloaded copy just preform a system transfer and your town is safe and fine as well
