This is awesome! I like how you matched the color of the ramp chasing leds to the mode. Are you just keying off of which insert is lit/flashing in the triangle grid near the flippers? Or are you reading the color info on the shot's insert/ST symbol as the ball enters the ramp? Im not a ST owner, so im not sure if those color always match. It seemed like in the multiball mode in your demo that the inserts were changing colors back and forth etc.
As a programmer ive got the wheels turning for all the possibilities.... Adding prem/le like GI lighting to a met pro for example...
Does the board have to drive strips, or could it drive multiple runs of normal led sockets like for GI?
Well done sir, well done!
