Retro Duo

The Retro Duo is a dual-compatible game system released by Innex. It is capable of playing both NES and Super Nintendo game cartridges in two separate slots. It uses two Super Nintendo-compatible game controllers as the main input for both systems' games. It is compatible with most games made for both systems, including PAL and NTSC Super Nintendo and Super Famicom cartridges; however, there are certain games that will not work or even work properly on the Retro Duo.
