Historical Context
The NAOMI arcade board made its debut during a time when arcade gaming was seeing a resurgence, particularly in the late 1990s. Sega aimed to capitalize on this trend, leveraging technology from the Dreamcast to create a machine that would dominate the arcade scene. This move allowed for an extensive library of games, many of which would later be adapted for home consoles.
Technical Specifications
The NAOMI hardware was built on a robust architecture that enabled high-performance gaming.
Core Components
- CPU: The Hitachi SH-4 32-bit RISC processor operates at 200 MHz and provides 360 MIPS and 1.4 GFLOPS.
- Graphics Engine: The PowerVR 2 (PVR2DC) facilitated advanced rendering techniques, making it capable of handling complex graphics and effects.
- Sound Engine: Utilizing an ARM7 Yamaha AICA running at 45 MHz, the NAOMI supported 64 channels of ADPCM audio.
Memory Configuration
The NAOMI features a main memory of 32 MB, with video memory of 16 MB and sound memory of 8 MB. This configuration allowed for smooth gameplay and high-quality audio, essential for immersive arcade experiences.
Game Media
The NAOMI utilized GD-ROMs, which could hold significantly more data than traditional ROM cartridges. The system reads the GD-ROM only once at power-up, loading the game into RAM, which minimizes wear on the mechanical components.
Influence on Game Development
The NAOMI platform was widely licensed, attracting numerous third-party developers. This openness led to a rich array of titles, including fan favorites like Marvel vs. Capcom 2, Dead or Alive 2, and Guilty Gear XX. The ability to run multiple boards in tandem also meant that developers could create visually stunning games that pushed the limits of arcade hardware.
NAOMI Variants
NAOMI 2
Released in 2000, the NAOMI 2 offered enhanced graphics capabilities and was compatible with most NAOMI titles. It allowed for improved resolution and increased memory, thus catering to the demands of more graphically intensive games.
Atomiswave
Developed by Sammy, the Atomiswave hardware was derived from the NAOMI platform, enabling a different set of games while retaining compatibility with many NAOMI titles.
Popular Games on NAOMI
The NAOMI board hosted several iconic titles that have left a lasting legacy in gaming history:
- Crazy Taxi: A pioneer of the open-world arcade experience.
- The House of the Dead 2: A standout in the light gun shooter genre.
- Virtua Fighter 4: A benchmark for fighting games with its depth and mechanics.
These games not only defined the NAOMI platform but also influenced gaming culture at large.
