The listing, 20 NES items has ended.
20 NES (Nintendo Entertainment System, 1980's) include from left to right: (top row) NES controller, NES Gun (for duck hunt, top gun, etc.), (2nd row) Concentration, Win Lose or Draw, Super Mario Bros/Duck Hunt, Super Mario Bros 2, Jeopardy, Sesame Street, (3rd Row) Wheel of Fortune, Caesars Palace, Sesame Street, Paperboy, Back to the Future, Techmo Bowl, (Bottom row) Top Gun, Golf, Double Dribble, Bases Loaded, Wrestle Mania, and Blades of Steel.
The Controller and gun both work fine. However, having no longer owning a NES, I was unable to test all of the games. I do know for sure that both Super Mario games work almost perfectly. Paperboy, Top Gun, Wrestle Mania, Blades of Steel, and Techmo Bowl also work well. I have no idea whatsoever if concentration, win lose or draw, Jeopardy, both sesame streets, Wheel of Fortune Caesars Palace or Back to the Future works. I do recall playing them a long time ago and they worked fine then, but I have no clue if they will work now. As for Golf, Double Dribble, and Bases Loaded, they all should work because they used to be my dad's favorite games and they worked the last time he played them. If there is any questions, please don't hesitate to ask.
