/***************************************************************************

GAME PLAN driver, used for games like MegaTack, Killer Comet, Kaos, Challenger

Modifications by Santeri Saarimaa:

3/6/1998: - CPU #2 is only for audio in all four games, added | CPU_AUDIO_CPU
          - A little louder sounds
          - Fixed MegaTack dip switches & input ports
          - Fixed Killer Comet dip switches & input ports
          - Fixed Challenger dip switches & input ports + coin slots
          - Added hi-score saving/loading for Challenger
          - Added hi-score saving/loading for MegaTack
          - Added hi-score saving/loading for Killer Comet

TO-DO: - Fix the input ports/dip switches of Kaos?
       - Graphics are still somewhat scrambled sometimes (just look at
         the tests with f2/f1)
