Well, it works in Linux and Mac too, but I really don't know how to setup libusb in these OSes. In Windows you use zadig and then boot the game, that's all. If it's compatible, the game just works as it would on a real Wii, otherwise it would ask you to connect the device, even if it's already connected...
