  X-Men
  
  driver by Nicola Salmoria
  
  notes:
  
  The way the double screen works in xmen6p is not fully understood.
  
  One of the screens probably has a buffer to delay it by 1 frame. If you
  hardcode buffering to the right screen, the intro is synced correctly,
  but in-game is not. Buffer the left screen and then in-game is correct,
  but the intro is not.
  
  The board only has one of each gfx chip, the only additional chip not found
  on the 2/4p board is 053253.  This chip is also on Run n Gun which is
  likewise a 2 screen game.
