This item has only been played for a few hours. A Famicom Tetris game (cartridge only, no box or manual) will be included as a bonus. Please refer to the photos after the first for the included items. Tetris, which was the only game tested, worked normally, but I don't own any other Famicom games, so I can't confirm if the others will all work. This is an amusement item. It worked properly when I played it. If there is a malfunction after purchase, please contact the manufacturer.
