DATEL has released a new software to transfer the Mii's from the Wiimote to the computer. This product include a Bluetooth USB adapter and let the user edit the Mii directly from the computer software. Freeware Mii's data transfer exists but some Bluetooth adapter don't work. Datel give it's own adapter and driver to ensure it's working. Description from CodeJunkies It doesn't tell if the user can send it back to the wiimote, or edit the Mac address of the Mii. Only a Bluetooth receiver, not transmitter ?
