'''Mii Maker''' lets you create Miis, like Wii Mii Channel. Here you can transfer Miis locally from other 3DSes, or from Wii Mii Channel. 3DS Miis can't be transfered to Wii Mii Channel, only from Wii.

3DS Mii QR is a standard 57x57 pixel Level 10 High ECC QR code with 'Mii' logo in center (refer to [http://www.denso-wave.com/qrcode Denso-Wave Inc] web site for QR Code format specifications). It contains 0x70-bytes of binary data. 3DS seems to have a fully implemented QR-code decoder, as it can interpret such Mii binary data being encoded even in the smallest possible for that data size Level 6 Low ECC QR code. The data itself is encrypted with AES-CCM, xorpads can be determined from known plaintext here. It's unknown what is used for the nonce. The Mii Maker application uses the [[NS]] APT Wrap/Unwrap commands to encrypt/decrypt this Mii data.

* QR codes made from the same 3DS for the same Mii are encrypted with the same xorpad (you can recreate it by xoring with known values from this table).

* QR codes made from the same 3DS for the same Mii are use the same AES-CCM nonce (you can recreate the xorpad by xoring with known values from this table).
