Interrupts:
CPU #0 (6309):
--------------
* IRQ: not used.
* FIRQ: generated by VBLANK.
* NMI: writes the sound command to the 6809.
CPU #1 (6809):
--------------
* IRQ: triggered by the 6309 when a sound command is written.
* FIRQ: not used.
* NMI: not used.
Notes:
* The protection is not fully understood(Konami 051733). The
game is playable, but is not 100% accurate.
* Missing samples.
