I'm confident I can get detailed timing measurements but as you say, actually implementing the timing in MAME may prove challenging.
Timing aside, I would otherwise be able to confirm whether or not our video emulation is pixel-exact under whatever cases I can test.

Has anybody looked at the Cave hardware specifically? If so, I'd be curious to hear about their methods and results.
