/*
 05/01/2003  MooglyGuy/Ryan Holtz
    - Corrected second AY (shouldn't have been there)
    - Added first AY's status read
    - Added coinage DIP
    - What the hell are those unmapped port writes!? Not AY...

 2003.01.01. Tomasz Slanina

  changes :
    - nmi generation ( incorrect freq probably)
    - music/sfx (partially)
    - more sprite tiles (twice than before)
    - fixed sprites flips
    - scrolling (2nd game level)
    - better colors (weird 'hack' .. but works in most cases ( comparing with screens from emustatus ))
    - dips - lives
    - visible area .. a bit smaller (at least bg 'generation' is not visible for scrolling levels )
    - cpu clock .. now 4 mhz
