Just got set up on our Wii U, trying to do 3DS and it's asking which Mii to use.
I don't wanna clobber our system Mii, seeing as it's also used for our regular NNID. I expected the whole "test account" thing to have a separate system Mii, but I guess not.
How do we go about doing this? Overwrite the PNID Mii with our 3DS Mii? But then it'd clobber it on Wii U – and we're using separate user accounts for NNID and PNID on Wii U.
I tried backing up and restoring the Miis' f000000b extdata with GodMode9, and that seems to work. So would the best way to back up, link, and restore? Or would that still be a ticking time bomb waiting to screw up one or both accounts' Miis?
