 Todo:

 - Sprite Mosaic <only used in Jaleco logo in P47>.
 - Sprite-Sprite Priorities <eg. Shingen, Kick Off, Hachoo>.
 - Kick Off seems unplayable.
 - What is YM3014 (M6295 compatible? Rodland uses one).
 - I think there might be volume control for the M6295, instruments
   are ok volume in Rodland, but explosions are too quiet. Or maybe
   the M6295 need different volume settings?

 Changes:

 08-02-99:

 - Fixed bug in Cybattler and 64th Street sub cpu memory map.

 24-01-99:

 - Added Rodland English Version
 - Changed AddMS1SoundCPU(), so it supports games with no M6295 samples (check
   PCMROM==NULL) and also support Cybattler and 64th Street (soundread from diff
   address).
