I testedAt the 2 power plugs of the Naomi.
Yellow = 12v
Red = 5v
Brown = 3.3v
White = Ground
I got an atx psu powering the supergun that goes to Capcom io then to the Naomi.. So I took voltage at the Naomi side and it goes like this
Yellow = 12v
Red = 4.87v
Brown = 3.21v
Thats the 8 pin plug I don't have anything on the 6 pin plug
