What I don't understand how it plays noises and the victory tune (Taps). Is part of the chip analog for the tone generation?

Does emulating this stuff fall into the Derek Renaud / couriersud domain?

It's nowhere near the complexity of something like pong, so hopefully, it won't need a Dice-level effort.

It doesn't look like it has analog sound generation hardware, it looks like it's all state machines. Still it needs someone good at tracing out transistors to work out what the transition tables are.
