  27. ; This is Howard Scott Warshaw's third game with Atari. It was conceived and
  28. ; developed in roughly 5 weeks! The licensing deal didn't complete until the
  29. ; end of July (in an interview Howard says July 25). Atari wanted this game
  30. ; for the Christmas season which meant Howard had to finish this game by
  31. ; September 1st!

  34. ; 1) ID_FOUR_DIAMOND_PITS
  35. ; 2) ID_EIGHT_PITS
  36. ; 3) ID_ARROW_PITS
  37. ; 4) ID_WIDE_DIAMOND_PITS
  38. ; - Objects are never placed in the overlapping pits for ID_EIGHT_PITS
  39. ; - Playfield is a 2LK while sprites are a 1LK
  40. ; - PAL conversion adjusts E.T. movement and colors
  41. ; - It seems RAM location $8B is not used
