The right-side of the device offers a port which allows a user to connect to another Game Boy system via a link cable, provided both users are playing games that support connecting to each other (most often, only copies of the same game, although for example the Pokémon games can connect between different generations). The port can also be used to connect a Game Boy Printer. The link cable was originally designed for players to play head-to-head two-player games such as in "Tetris". However, game developer Satoshi Tajiri later used the link cable technology as a method of communication and networking in the popular "Pokémon" video game series.
