                            Differences  | 
                
                  | The option to select the
                      number of ghost monsters is missing. 
 | 
                
                  | There is a Teddy Bear
                      (beginner) level that can be selected.  The Teddy
                      Bear is worth 50 points. | 
                
                  | One or two players is selected directly with the #
                      key instead of being combined with selecting the number of
                      ghost monsters. 
 | 
                
                  | The Y in PLAYER and the V in LEVEL are filled in
                      more. 
 | 
                
                  | The PLAYER and LEVEL text are spaced further apart
                      vertically. | 
                
                  | Almost all the sounds are different and not as
                      polished. 
 | 
                
                  | Some sounds (power pellet, ghost eaten, eyes
                      returning, and death) are taken directly from the 5200
                      port of Ms. Pac-Man. | 
                
                  | There is a major bug where if the player dies
                      while the prize is destroying the power pellet it will
                      stay on the screen but can't be eaten.  This
                      effectively soft locks the game as the level cannot be
                      cleared. | 
                
                  | The game doesn't automatically go back to the
                      title screen at the end of the game. | 
                
                  | The ghost monster AI is tougher.  It was
                      toned down a bit for the final release. | 
                
                  | A rare glitch can occur where a ghost monster gets
                      trapped under the maze in the status bar area.  This
                      can happen after the power pellet bug is triggered, but
                      it's not sure how. |
