Mii's are portable on your Nintendo Wii. This means there are a several places where Nintendo Mii's can be saved. The primary storage is on the Secure Digital Card (SD Card) flash memory that you can insert inside your Nintendo Wii. Another way you can save your Mii is on the save data for the Wii Remote.
However, the first time you try to save the Mii to your Wiimote, you may encouter the following message:
"There is no Mii save data on your Wii Remote. Format this save data?"
While this message may be concerning, simply select "Yes" if this message appears. It simply means that you have never saved a Mii to your Wii Remote, and the Wii Remote needs to be prepared before a Mii can be saved to it.
After your first save, you should no longer encounter this message when you attempt to save Mii data to your Wii Remote.
