Notes

update 20210129: better description, better pics, confirmed dump.
I dumped a sound board for this game back in 2007. A few years later (2013) Any dumped a full board.
There is only 1 difference between the two dumps:
sound ROM .4h is 2716 (size 2048 Byte) on my board, but Any's dump is double size (4096 Byte) with both halves identical.
So, most probably Any's dump is not correct and MAME shpuld be updated to support ROM as verified on real PCB.
