I had a look at the IRQ code in all those listed games.

They all treat an IRQ that hasn't come from one of the PIAs as an unknown interrupt so force a system reboot.

The interrupt vector points to code that first checks for an IRQ sourced from:
~ CA1 of U11 PIA - Display interrupt generator
if not, then check:
~ CB1 of U10 PIA - Zero Crossing interrupt
if not, then check:
~ CA1 of U10 PIA - Coin door self test button
if not, the interrupt is from an unknown source so REBOOT the system.

There's no check for the IRQ being sourced from the SB-300.
