Namco NB-2

The Namco NB-1 is a 32-bit arcade system board which was first used by Namco in 1993; NB-2 has a different memory map, more complex sprite and tile banking, and two additional ROZ layers over the NB-1. Great Sluggers: New World Stadium was the first game to use this board - and the following year, Nebulas Ray, Great Sluggers '94, J-League Soccer V-Shoot, Point Blank (original name Gun Bullet), The Outfoxies and Mach Breakers: Numan Athletics 2 were released on it. In 1995, the eighth title for Namco's long-running World Stadium series was released, Super World Stadium '95 (which borrowed heavily from that original Great Sluggers); in the two following years, it was followed up by Super World Stadium '96 and Super World Stadium '97, the second of which was the last game to use it.
