I have found a lot of threads about Ataris that will not show color, but I may be having the opposite problem. I have a light sixer. The color switch doesn't have any effect on my games, as in the games stay in color even when I toggle black and white. Hi I am not sure if the switch is broken or if the two games I have do not support black and white mode? I have only been able to test Berserk and SwordQuest.
