The NAOMI (New Arcade Operation Machine Idea) is an arcade system released by Sega in 1998. It was designed as a successor to Sega Model 3 hardware, using a similar architecture to the Sega Dreamcast.
The NAOMI was succeeded by the Sega Hikaru and Sega NAOMI 2 boards, though having out-lasted the NAOMI 2, Hikaru and Sega Aurora. The Sega Chihiro, or possibly even the Sega Lindbergh, could also be seen as successors.
The NAOMI board and almost all of its variants were united in common by running on mostly the SH-4 32-bit RISC CPU. Next, all but two of these various boards shared their own form of the PowerVR 2 graphics processor with some differences in specifications (eg. either single or twin CPUs). The exception was the Cave CV1000 which ran on a Hitachi SH-3 CPU and its GPU was the Altera Cyclone EP1C12 FPGA. Many of them also utilized their own Yamaha audio chipset. Sega Hikaru had its own Sega Custom 3D GPU composed of dual PowerVR 2 GPU chips.
Arcade Boards
- Sega NAOMI (1998–2009)
- Sega Hikaru (1999–2002)
- Gaelco PowerVR Based (1999-2002) [N 1]
- Sega NAOMI 2 (2001–2006) [N 2]
- Sammy Atomiswave (2003–2009)
- Sega System SP (2004–2009. AKA "Sega Aurora")
- Cave CV1000B (2004–2007) [N 3]
- Cave CV1000D (2008–2012)
- ↑ PowerVR 2-based board from Spanish company. Not their early 'Gaelco 3D' board from 1996-1998. There is also an inactive emulator for the unrelated earlier Gaelco 3D system, and MAME likely supports that one.
- ↑ A prototype version of an unreleased game called Jet Squadron was made on the NAOMI 2 board in 2000 but other officially released games started in 2001.
- ↑ The 'arcade_compat.txt' file inside DEmul's release archives do not have any Cave CV1000 emulation compat list, so its games' status are unknown.

Comparisons
- DEmul is a closed-source emulator for Sega Dreamcast and arcade boards of Sega NAOMI and follow-up variants, including the NAOMI, Atomiswave, Hikaru, Gaelco, NAOMI 2, System SP (Aurora) and couple Cave CV1000 systems. Only non-MAME arcade ROMs work here.
- reicast libretro is the libretro core of the independent reicast emulator and seems to be more advanced in overall compatibility and feature levels of Dreamcast and several arcade boards emulation. It is possible that some optional hacks are used to achieve correct graphics on some compatible arcade games.
- nullDC was the first independent, open-source Dreamcast emulator to attempt emulation of the NAOMI arcade board. Its compatibility is unknown, so is not included in the NAOMI compatibility chart below. The emulator has since been superseded by its follow-up spin-off, 'reicast', although that one doesn't yet have any arcade board support. However, its libretro arm now supports partial emulation of NAOMI and Atomiswave boards.
- MAME is a long way behind DEmul in terms of compatibility, but is being actively developed. It is shown to have adequate support of the NAOMI (Most games could show graphics & some are playable), and preliminary support for Atomiswave and Hikaru boards and at least BIOS support for NAOMI 2. v0.191 (Oct 2017) supports SuperH CPU cores and has a preliminary SH3/SH4 recompiler for CV-1000 only. NAOMI & Hikaru driver emulation were still being worked on since then up to 0.201 (Aug 2018). Game compatibility probably not available.

** DEmul: The arcade boards' compatibility lists for DEmul can be found inside the 'arcade_compat.txt' file inside DEmul's release archives. It covers most boards but not the Cave CV1000 boards. Also see naomi.compat.txt.
*** MAME: MAME has working but incomplete NAOMI board emulation. Some games are playable. Support for several other boards (i.e. System SP/Aurora & Hikaru) are very basic.
**** Ports: Some games were ported to consoles available when the arcade games where released. Many or a few of them from the NAOMI board have come on Dreamcast, PlayStation 2, Xbox and Windows.
