This accessory was very common. It's a light gun. It was used for many games, such as ''Duck Hunt'' and , ''Wild Gunman'' , and ''Hogan's Alley'', just for two three examples. It's a light gun. 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. 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.
