I was hooking up an old model 1 Genesis, couldn't find the power supply for it. I had a bunch of model 2 power adapters but no elusive model 1. So..... Me being impatient tried a couple other very random power adapters, none worked. Upon finally finding the correct one it powered on. Weird thing is only some games are working. It seems I have a pork el with any and all EA games but I was able to get MK, Beavis and Butthead and Outrun to work. Then I tried B&B again, and the Sega screen came on but then the screen started going haywire. I even tried cleaning the games and system to Bo avail. Did I screw this model 1 up??
