Technos Mysterious Stones hardware
driver by Nicola Salmoria
Notes:
* The subtitle of the two sets is slightly different:
"Dr. John's Adventure" vs. "Dr. Kick in Adventure".
The Dr John's is a bug fix. See the routine at 4376/4384 for example.
The old set thrashes the Y register, the new one saves in on
the stack. The newer set also resets the audio chips more often.
