No, it's sounds like a typical clone. of course co-processor games won't work on it. It might even be incorrectly hooked up. Also the video is probably shit because the real Genesis composite is shit. What I'm curious about is audio distortion and button mapping.

buzz_n64, you said you have Mortal Kombat 3. Please go into the controls option and see what the Genesis buttons are mapped to on the SNES pad. please make us a chart.
