2. What Constitutes a "Full ROM Set"?

In the context of arcade emulation, a full ROM set refers to a complete, non-merged collection of all known, dumped, and working software releases for a given hardware platform. For Sega NAOMI, this includes:

1. Ferrari F355 Challenge (Twin/Deluxe) – Requires special CHD and analog controls. Most sets include it, but few can run it.
2. Spawn: In the Demon’s Hand – A cult classic 4-player brawler. The Japanese version has more characters.
3. The Maze of the Kings – A rare Sega puzzle game that uses a trackball.
4. World Kicks – A soccer game that is broken in most sets due to bad PIC dumps. A "top" set contains the corrected dump from 2022.

1. Introduction to the Sega NAOMI Platform

The Sega NAOMI (New Arcade Operation Machine Idea) is an arcade system board released by Sega in 1998. It was designed as a low-cost, high-performance alternative to Sega's earlier Model 3 hardware, leveraging off-the-shelf components to reduce manufacturing costs and simplify game development. At its core, NAOMI is essentially a Dreamcast console in arcade form, sharing the same Hitachi SH-4 CPU, PowerVR2 graphics chip, and 16 MB of main RAM.

This architectural similarity has two major implications: Appendix B – Key Redump/No-Intro Status

• Arcade-Perfect Ports: Dreamcast home conversions of NAOMI games are often extremely accurate.
• Emulation Synergy: Emulators for NAOMI (like Demul, Flycast, or Reicast) heavily borrow from Dreamcast emulation techniques.

Unlike traditional ROM-based arcade boards that stored game code on mask ROM chips, NAOMI games were distributed on:

• GD-ROM discs (Gigabyte Discs, similar to Dreamcast discs) for the NAOMI GD-ROM drive attachment.
• Cartridges (officially called "NAOMI Cartridges" or "ROMEO" boards) for faster loading and lower latency.
• CompactFlash or Network booting (later revisions and arcade operators could load games from CF cards or over a network via the Sega ALL.NET service).

Because of this variety, a "Full ROM Set" for NAOMI is not just a collection of .bin files—it includes disc images, cartridge dumps, BIOS files, and often associated device firmware.

11. Conclusion

A Sega NAOMI Full ROM Set is a precisely defined digital artifact comprising 178 game ROMs, 62 GD-ROM CHDs, and 12 BIOS variants, totaling ~52 GB compressed. It is maintained by the MAME project and remains the definitive reference for NAOMI preservation. No commercial source exists; acquisition is limited to self-dumping or archival collections. For emulation, Flycast and MAME provide complete support when the set is correctly structured using official DAT files.
