Steps for bringing a Mii extracted from a Wii with SaveGame Manager GX (.miigx) into a modded Nintendo Switch
Tested on my Switch V2, EmuNAND 20.5.0 with Atmosphere 1.9.5
First of all, make sure you have nx-ovlloader, an overlay menu like Tesla or Ultrahand and emuiibo installed on your modded Switch.
- Install the 'Amiigo' homebrew and download a random Amiibo (i've used R.O.B. - NES from Super Smash Bros);
- go to https://mii-unsecure.ariankordi.net/
- upload your .miigx and convert it into a .charinfo file;
- rename the output file from the website to 'mii-charinfo.bin';
- FTP into sd:/emuiibo/amiibo/(amiibodirectoryname);
- replace the existing 'mii-charinfo.bin' file with the one you've downloaded from the website;
