Here's a very half-arsed attempt at implementing lighting:
I actually have an MK4 PCB that was given to me by Aaron. I've been meaning to write a test program to thoroughly exercise the hardware but haven't yet gotten round to it. There's so much unknown state and with only two games produced for the hardware, there aren't enough use cases to infer what does what. Did I mention that the ZEUS chip has downloadable microcode too? :S
