For those lucky enough to own physical NAOMI hardware, netbooting represents the purest way to play exclusive ROMs. The netbooting process involves loading game images directly into the NAOMI's memory over an Ethernet connection, eliminating the need for expensive original GD-ROMs or ROM cartridges. The project, which runs on a Raspberry Pi, has made this process remarkably accessible, providing full support for all netbootable Sega arcade ROMs for NAOMI, NAOMI 2, Triforce, Chihiro, and Atomiswave conversions. With a netdimm board running firmware 3.03 or greater, enthusiasts can create a hardware setup that boots their entire exclusive NAOMI collection from a simple network connection.
Some games, while technically sharing a name with a console release, existed in a superior, exclusive form on the NAOMI board: sega naomi roms exclusive
Some NAOMI games received home ports that were compromised, making the arcade ROMs superior.

Naomi exclusives are more than just forgotten games – they represent a transitional moment in arcade history. The Naomi was powerful enough to host complex 3D engines, yet many of its exclusives experimented with unique controls (trackballs, light guns, force-feedback wheels, card readers) that home consoles couldn’t replicate affordably. Emulating these ROMs today often requires special controller mappings or even original I/O boards. : Using large cartridges or GD-ROMs with a

Developed by Dimps and SEGA, SlashOut is a 3D hack-and-slash beat-'em-up heavily inspired by the Golden Axe series. Set in a high-fantasy world, players choose from distinct warriors to battle hordes of monsters. It features deep combo systems, magic spells, and multi-tiered boss fights that would have made it a smash hit on consoles. 6. Zombie Revenge (Arcade Version)
An arcade-exclusive simulation game where you play as a safari ranger rescuing animals. It is notable for its unique cabinet featuring a fishing-rod-style controller, making it nearly impossible to replicate perfectly at home without specialized emulation, but the ROM offers the full, quirky experience. 6.
This hardware gap created a unique category of games: titles that were technically possible on home hardware but required downscaling or significant optimization. Consequently, several developers chose to keep their most ambitious projects exclusive to the NAOMI hardware, making the preservation of these ROMs essential for experiencing the games in their intended fidelity.
