Yesterday i made it :P if you want it too, you just have to download a program named "dolphin emulator", which runs both on mac and pc. then you have to buy one or more wiimotes and a sensor bar, and if you don't already have it, a bluetooth usb. The first one can be found on ebay for around 25€/controller + nunchuk, not original naturally. the sensor bar costs around 10€ and the bluetooth... i don't know, i didn't have to buy it...

so 2 controllers and a sensor bar is just 60€... i already tried, the graphic is almost better than the wii's one... the negative thing is that you'll need a big monitor =\ i have 21,5" and it's still a bit small...
