I just received my LED light harness from Ultimarc and have it correctly plugged into my iPac4.
I have checked off the PS2 LED Lights option in Mame 32, but there is no exciting lights to lure would-be-arcaders to my machine.
The reference card indicates it only works when certain buttons are pressed, but that doesn't seem to work neither. I was hoping to hook it up to my illuminated Happ buttons (currently used as coin-up buttons until I get a coin door) and have them flash when being prompted to coin-up.
Any thoughts?
