=== 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 core|reicast libretroBeetle DC]]''' 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 Sega 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 The emulator has since been superseded by its follow-up spin-off, 'reicast', although that one doesn't yet have any arcade board support.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 [https://wiki.mamedev.org/index.php/MAME_0.127u1 BIOS] support for NAOMI 2. [https://wiki.mamedev.org/index.php/MAME_0.191 v0.191] (Oct 2017) supports SuperH CPU cores and has a preliminary SH3/SH4 recompiler for CV-1000 only. NAOMI & Hikaru driver emulation was still being worked on since then up to [https://wiki.mamedev.org/index.php/MAME_0.201 0.201] (Aug 2018).
