STEP 1
Once the Mii Maker is open, you will be at the main menu. Here, you need to press the option QR Code/Image Options.
STEP 2
Now you will see two options. Of course, you do not need both QR options so choose the third one: Save Mii as Image.
STEP 3
Once you’re here, you will need to select your Mii and choose if you want to do just the face or the entire Mii. Meanwhile the latter option has a different name in both versions, it’s the same thing.
In the case of the 3DS, it will be exported once chosen. The Wii U version will offer an extra page instead, offering different faces or positions.
Remember you will not be able to export your Mii if you do not have a SD card inserted in the console. Meanwhile a SD card is included with the 3DS, you will need to get one for your Wii U. A micro SD with an adapter also works, but I don’t recommend it at all.
STEP 4
Congratulations! You now have the pic of your Mii on your SD card.
