'''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.
'''Mii Maker''' lets you create [[Mii]]s, and is the successor of the Wii's Mii Channel.
It can transfer Miis over [[NWM_Services|local wireless]] from other systems running Mii Maker (3DS/Wii U), or receive, but not send, from Mii Channel.

The Wii beacons are similar to the usual multi-cart NDS beacons, except: beacon_type is zero, and payload size is 0x14. The payload data is just the Wii UCS-2 nickname, with some extra unused zero data. The usual multi-cast NDS protocol is used for sending the 3DS nick to the Wii. After many keep-alive frames, it eventually sends a bunch of frames, each containing the whole Mii. There's a 6-byte header, followed by [http://wiibrew.org/wiki/Wiimote/Mii_Data Mii data]. At the end of these frames like most NDS frames is the 0200 byte marker.

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 contain 112 byte of binary data. 3DS seems to have 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 ciphered, algorithm is unknown yet.
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. The Mii Maker application uses the [[NS]] APT Wrap/Unwrap commands to encrypt/decrypt this Mii data. For the NS [[APT:Unwrap|Unwrap]] command, the Mii Maker application uses nonceoffset=12, noncesize=10, and inputbuffer-size=0x60. Note that the actual nonce size is 8 bytes due to Wrap/Unwrap implementation, and the nonce data should be moved 12 bytes afterwards after decryption. The rest of the data at 0x8-0x5F is encrypted, and should be split into two parts after decryption, with the nonce data in the middle. (See [[APT:Wrap|Wrap]] and [[APT:Unwrap|Unwrap]] for more information)
