This is an accessory that lets you enjoy Game Boy games like an arcade machine. Includes the instruction manual and box. Batteries not included. The light bulb turns on (see photos 3 and 4), but since I don't have a Game Boy, I haven't confirmed its operation. The joystick and buttons feel fine. The box has scratches and wear as it's over 30 years old. This is a very old item and has been stored by a private individual, so please refrain from purchasing if you are concerned. #GameBoy #GB #RetroGame #Rare #KONAMI #ArcadeGame
