So what I have here is a prototype of Global Galdiators on the Sega Genesis. It has some adaptor plugged into the bottom of it and fits perfectly into the Sega Genesis. There is some writing on it that says Mc Kids II 6-15-92. When you put the cart in a screen comes up with some contact info and the name David Perry. The game gives you the option to change stages and difficulty. There are no copyrights on the title screen but it does say Global Gladiators.

I made a photo album of it here: http://imgur.com/a/Q1KS7...
