Four Score Multiplayer adaptor Nintendo NES Video Game Accessory
The NES Four Score is a multitap accessory created by Nintendo in 1990 for the Nintendo Entertainment System. Select games can utilize it to enable up to four-player gameplay. The NES Four Score is similar to the previously introduced NES Satellite, a device that allows four players to connect to the NES and extends the range using infrared wireless communication.
Prior to the advent of multitap support on NES, the NES games which support more than two players, require the players to pair up and then alternate turns while sharing the same pair of NES controllers. Some games that originally feature support for more than two players, such as some arcade games, support only two simultaneous players in their NES versions.
On the NES Four Score, there is an option to switch between two-player and four-player modes, and there are turbo A and B buttons that give any of the connected controllers a rapid fire boost. The NES Four Score can also be used as a controller extension cable because the wire which leads from the accessory to the NES is several feet in length
