Dumped the internal ROMs, near perfect match with the optical readout.
Glitchy values in volume LUT confirmed, nice job Konami 👍

this looks like what happens when the binary address ordering is wrong...

I'm out of time, right now, but if you chop this into 8ths and re-arrange it, does it look better?

No, the glitchy values wouldn't fit better anywhere else. Plus the busses used for readout are also used for testing the multipliers and those give out all the expected values, so I'm quite sure about the bit order.
