Utilizing the serial I/O port found on the back of most PlayStation models, it allows for two consoles to be connected in order to play compatible multiplayer games on separate consoles and displays.
It is not compatible with the redesigned PS one or newer PlayStations.
The accessory was released in 1995 retailing for ¥2000 in Japan[2] or $40 in the United States;[3] it was released later than expected due to the delay of Metal Jacket, which was supposed to be the first title to take advantage of the cable.
[4] The main advantage to using the cable is that a split-screen would not be necessary for multiplayer, increasing each player's screen size and potentially increasing game performance (as only one view has to be rendered per console).
This expense was impractical for most consumers, and by the end of 1997 most retailers were no longer carrying the PlayStation Link Cable.
