Step 1: What you will need
-Candles (or sensor bar if you want it to be more accurate, there are several guides on Instructables)
-Suitable Bluetooth drivers (to my knowledge Bluesoleil may not work)
-Winremote (found free from http://onakasuita.org/wii/ )
If you do have the Bluesoleil drivers, you may want to look into WIDCOMM drivers (I use these) from here: http://www.devilived.com/2006/05/02/widcomm_bluetooth_stack_v5012500.html
After you have these, progress to step 2
Step 2: Pairing the Wiimote to the computer
1.Use the drivers to search for devices and press 1 and 2 on the Wiimote to try pair to the computer. Make sure the Wiimote does not turn itself off until it has been paired (i.e. press 1 and 2 every now and then)
2. Select the service 'Nintendo RVL-CNT-01' or something similar.
Your Wiimote should light up player one and player two and the drivers should recognise the Wiimote. At this stage, you may want to look into mii downloading from the great program located at http://www.miimall.com/ which allows you to download and upload miis.
Step 3: Open up Winremote
After loaded up, click options and "cursor ON/OFF"
This should allow the remote to work, sometimes even without the candles but the candles will allow a more steady signal if your bluetooth adapter is far away from the remote. Place the candles appart by about the same as a Wii sensor bar and light them up. Hey presto! It works!
