This accessory was very common. It's a light gun. It was used for many games, such as ''Duck Hunt'', ''Wild Gunman'', and ''Hogan's Alley'', just for three examples. When the trigger is pulled, the screen for 1-2 frames flashed black with a white rectangle (the target to shoot at). If the gun detected it was pointing at the white, it told the game to register a hit. Real hardware, this was very hit or miss, and plugged into controller slot 2. It mainly worked with old CRT TVs. Newer TVs will not register with the Zapper. Many emulators support this accessory with 100% accuracy hit detection, usually with a mouse click (PC), tap (for mobile), remote ([[Wii]] ports of NES emulators), or faked pointers using a controller. ===Family Trainer/Family Fun Fitness/Power Pad/===This accessory is very different from a standard controller of eight buttons. It was designed to be a controller where you need to use your feet, typically by running in place on numbered circles to represent button presses. It plugs into controller slot 2 and is 12 different buttons. Notable games, such as ''Stadium Events''/''World Class Track Meet'' and ''Athletic World'', utilize this accessory. Trying to use a standard controller anyways won't work. Despite being less accurate than puNES or Mesen, [[FCEUX]] supports this controller.
