+ 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.
