I have had problems where not enough voltage would cause a console to freeze or shut down, but I am not familiar with the problems caused by not enough amperage. I'm currently trying to get an official Sega Genesis I adapter or similar so I can verify that it is indeed the adapter's fault. Would 1A be enough? I've seen posts that claim that the Sega Master System needs anywhere from 850 to 1200mA.
