whell the infrared port
you need to buy 2 led infrared (if I renember whell less 10 cent)
and put a battery or conect to a transformator or make a cable with the usb (5v have the usb)
or take a wii sensor bar and put to the transformator (adaptor for pass 110V to little volts '1 to 12V the universals')
but the wii sensor not are cheap
probably you can by a not official

and the same of the wii
under or over the lcd

appear if work with also with two candles (emit infrared ligt)
but probably with the time is more expensive

you can move the cursor if you use the infrared bar

motion support: If you refer if you move rapidly the wiimote
appear the driver support all the funtions of wiimote
all depent of the software you use

Any bluetooh adaptor work, personally i have the concentronic
CBT200U2 is old but support bluetooh 2.0 and a distance of 100m
