Notes : This board was very expensive to produce and was only really designed for one game (Brave Fire Fighters) as it could do complex fire graphics. There were eventually only 6 games made for this system, and it was dropped in favour of the Naomi 2.
It was also the first arcade board to be able to do phong shading.
