I have some legit .cias and I have some questions about them: 1.I want to install them on my old 9.2 3DS.But the NNID that is on it is already on a new 3DS system. So can I format the Systemnand without updating? 2.Do I have to install the legit .cias on Emunand or Sysnand? 3. Can I register the legit .cias to an new NNID (NNID will be created and added to the old 3DS before I install the .cias), then unlink the NNID from the old 3DS,link the NNID to my sisters new 9.9 3DS and redownload the games from the e-shop for free on this?
