RetroPad NES controller RetroZone takes original controllers from NES, Super Nintendo, Genesis, Atari, and Intellivision and converts them into USB game pads. You can now have emulation with the real controllers. I already have one of the top-loading NES systems from 1993 with the “dog bone” controllers. I like to have the full system, but finding and storing the games is difficult. Emulation combined with a nice controller is a good solution.
