  2.     Driver For DECO   ASTRO FIGHTER/TOMAHAWK 777
  3.  
  4.     Initial Version
  5.  
  6.     Lee Taylor 28/11/1997
  7.  
  8.  
  9.     Astro Fighter Sets:
  10.  
  11.     The differences are minor. From newest to oldest:
  12.  
  13.     Main Set: 16Kbit ROMs
  14.               Green/Hollow empty fuel bar.
  15.               60 points for every bomb destroyed.
  16.  
  17.     Set 2:    8Kbit ROMs
  18.               Blue/Solid empty fuel bar.
  19.               60 points for every bomb destroyed.
  20.  
  21.     Set 3:    8Kbit ROMs
  22.               Blue/Solid empty fuel bar.
  23.               300 points for every seven bombs destroyed.
  24.  
  25.  
  26. To Do!!
  27.        Figure out the correct vblank interval. The one I'm using seems to be
  28.        ok for Astro Fighter, but the submarine in Tomahawk flickers.
  29.        Maybe the video rate should 57FPS as the Burger Time games?
  30.  
  31.        Rotation Support
  32.  
  33. Also....
  34.         I know there must be at least one other rom set for Astro Fighter
  35.         I have played one that stoped between waves to show the next enemy
