Fast Facts on the Sega NAOMI
Made by: Sega Variants: Sega NAOMI GD-ROM, Sega NAOMI Multiboard Released in JP: 1998

The Sega NAOMI (New Arcade Operation Machine Idea) is a development of the Sega Dreamcast technology as a basis for an arcade system board. The first NAOMI hardware was demonstrated in 1998 at JAMMA as the successor to the Sega Model 3 hardware. The use of mass produced hardware allowed for a sharp reduction in the cost of complete arcade cabinets.

The NAOMI and Dreamcast share the same system-architecture. Both systems use the same Hitachi SH-4 CPU, PowerVR Series 2 GPU (PVR2DC), and Yamaha AICA based sound system. NAOMI packs twice as much system and graphics memory, and 4X as much sound memory. And although the NAOMI and Dreamcast operate at the same speed (clock frequency), multiple NAOMI boards can be 'stacked' together to achieve better graphics performance or a multi-monitor setup. The other key difference between NAOMI and Dreamcast lies in the game-media. NAOMI uses either (ROM PC-board) or Dreamcast's GD-ROM optical-storage. A ROM system is capable of storing 168 MB of data.

Two more variants existed:

• Multiboard — (TODO info needed; see replace tag above)
• Satellite Terminal — independent NAOMI cabinets connected to a master one

NAOMI boards can be used in special game cabinets (NAOMI Universal Cabinet) where a theoretical maximum of sixteen boards can be used in a parallel processing format.

Unlike most hardware platforms in the arcade industry, NAOMI is widely licensed for use by other manufacturers. Games such as Mazan and Guilty Gear XX are examples of NAOMI-based arcade games that are not Sega products.
