Evolución de su predecesora.



Compatibilidad total con juegos de Naomi (1).

La novedad más destacable está en los efectos de luz que es capaz de generar



Introducción


SEGA mostró Naomi 2 en Japan Amusement Machinery Manufacturers Association (JAMMA) en otoño del 2000 en el Arcade show en Tokyo, Japón.
