NES Four Score

The NES Four Score and NES Satellite are multitap accessories produced by Nintendo for the Nintendo Entertainment System (NES). With supported games, both peripherals allow the connection of up to four controllers to input simultaneously on the NES; they are interchangeable in their compatibility with supported games. The major difference between the NES Four Score and the NES Satellite is that the former connects directly to the NES, while the latter uses infrared wireless communication instead; the latter acts as a range extender adaptor for all wired controllers, extending the usable range from around 3 feet (for a standard controller) to 15 feet.
