Retro Duo (Nintendo/ NES 3rd Party Console) with Mario Bros

Selling a 3rd party Nintendo unit that plays original Nintendo and Super Nintendo cartridges. The Super Nintendo slot does not work, but NES cartridge slot plays fine. It comes with Mario Bros and an NES Gun, along with all the cables and single controller. The Zapper Gun does not connect with the system. It also comes with authentic Contra Super C & Ninja Gaiden, though neither game functions on any of my currently owned, authentic and 3rd party, hardware. Price is firm.
