Use the sliders to create a Mii. Click the yellow buttons to change the Miis info. My Mii if you want it: 1331112 N: RFGuy1378490 C: (just do no creator) M: 11 D: 1 MATT: 8441667 N: MATT C: WiiSports M: 00 D: 00 This is for both mobile and pc.
My Avatar Editor (the real one): myavatareditor.com Copy and paste the link to open. NOTE My Avatar Editor has been discontinued. But there's another My Avatar Editor that works: https://rc24.xyz/goodies/mii/ Again, Copy and paste this. Theres one important thing I need to tell you about this project. If you load in a Mii, the creator, nickname, and birthday will not be there. So maybe when you send people Mii codes, maybe type in the nickname, creator and birthday at the end of the code. Example: 1234567 N: Mii C: Username M: 00 D: 00. I was thinking that N: is nickname, C: is creator, M: is for month, and D: is for day.
