The NES Advantage featured adjustable turbo controls for the A and B buttons which could be toggled on or off with a button; users can adjust the rate of the turbo (i.e. how quickly the A or B button is pressed) by adjusting the respective turbo dials located above both buttons. It features a pseudo slow motion feature in which users can toggle on and off by pressing the "slow" button. However, the slow motion feature did not work with all games, and it did not work with games compatible with the NES Zapper or Robotic Operating Buddy. The slow button very rapidly pressed start, which could lead to problems when the player attempts to do an action (i.e. jumping or firing.) This was not compatible with games with start menus or pause screens. Finally, the Advantage was able to be shared with another player in games where two players alternated gameplay by toggling a switch between "Player 1" and "Player 2".
