All these bugs can be cured by a simple 1-byte patch: in the manual, are you guys sure that's what it was intended for "in the factory"?
ROM_FILL( 0x47e5, 1, 0xc3), but why is it necessary? However you were correct in thinking the schematics were wrong. My multimeter found
the following:
15k resistor - pin 7
39k - pin 10
82k - pin 12
It looks like they have Sx2 and Sx4 the wrong way round on a latter page of the schematics."
4. The "Hard" mode bug can be fixed with a single byte patch: ROM_FILL( 0x47e5, 1, 0xc3)
5. I have seen real machines with Hard mode set, that worked properly, thus there
must be yet another romset still waiting to be found.

music/explosion. This didn't happen on the real machines I played.
