I've made some interesting progress.
So, as you may have guessed, there are two sounds layered to make the Jackpot sound. Those are in two codes.
7a 0d (7a is a bank switch command)
now, in my video you can see the difference between just the first sound called and the other with both sound called in togheter. My guess is that some audio cards misses the second sound, and the right (as the request by the CPU on the bus) sound is the one with the crashes. I've tested all ROM from P-4 to 9.4H, and all call this sequence. I've tested also with the Powerball, and I'm noticing that my real pinball when I get the jackpot with the powerball yells "Powerball" and then "Jackpot!". I've discovered that if you have the L-4 or the L-5, then you have this feature I think is neat Is in the code that transit in the bus between CPU and sound board. This is somewhat missing in 9.2 and 9.4H
