[How to] transfer Miis from your computer
This will require a computer that has either internal bluetooth or a USB bluetooth adapter, If your Bluetooth adapter does not use the MS stack, you will need to change the driver. Open up the Device Manager and go to your Bluetooth adapter. Right click and select Properties. Click on the Driver tab and choose Update Driver. Select the "Install from a list" option then choose "Do Not Search...I Will Choose a Driver To Install". Uncheck the "Show Compatible Hardware" box and find the Microsoft Bluetooth Stack in the list of drivers. Select it and finish installing it, then you must restart your computer for the changes to take effect.
If your Bluetooth adapter is correctly installed, you will have a Bluetooth icon in your taskbar tray. Open the application and search for a bluetooth device, and then add a new bluetooth device.
Press the 1 & 2 buttons on your Wiimote. The blue lights on your controller should start to blink. Once the Bluetooth software has detected your controller, continue to install it. If prompted for a passcode, select Do Not Use a Passcode With This Device. You may need to press 1 & 2 on the controller again to complete the synchronization.
your wiimote should have successfully connected to your computer and should be done syncing, if not retry the steps above.

The mega mall hooks up to a server and can download various miis ranging from arnold to ZZ top :D
Then read the readme.txt file inside of the download to use the application (its pretty easy since it is a GUI program)
