One of the earliest Wii clones was the Sport Vii by Jungletac, which came with 2.4g wireless controllers duplicating many features of the real Wii's, including accelerometers and a built in speaker. However very few subsequent clones have such features, and the controllers supplied with vast majority of Wii clones sold today are infrared Famiclone-style controllers with a simple motion sensor mapping any sharp movement to the A button. These are essentially an evolution of the single-game plug-and-play consoles (usually Famiclones) released prior to the Wii, which used similar technology to play ping-pong, tennis, boxing etc, usually with only one game per unit.
