I want to create a new NNID but I have to format my system. I'm worried that I will lose my data on Alpha Sapphire. Please let me know if I can format my system without deleting my AS data
no. I did it with my Y, Omega ruby, and pearl game but no effect at all.
No, if your game is a physical cartridge and not a downloaded version, formatting your system memory will not do anything, as data is saved to the cartridge and not the system.
