Released by Sega in 2001, the NAOMI 2 (New Arcade Operation Machine Idea 2) was designed as a significant upgrade to the original NAOMI board, which was itself almost identical in architecture to the Sega Dreamcast. While the original NAOMI provided arcade-quality ports of Dreamcast games, the NAOMI 2 was built to deliver visuals far beyond what the home console could achieve.
The physical hardware that ran these games—the NAOMI 2 boards, GD-ROM drives, and security chips (DIMM DIMM)—is aging. Over time, these components degrade, leading to the permanent loss of the software.
Here are some of the most notable and beloved NAOMI 2 titles:
Arcade preservation differs from standard console emulation. Naomi 2 games generally exist in two formats within an archive: Sega Naomi 2 Roms Archive
An archival image (usually converted to a decrypted .bin format) can be hosted on a local server device. When the NAOMI 2 arcade hardware turns on, it requests the file via network protocols, loads it into the DIMM memory, and plays the game exactly as it would have in an arcade cabinet in 2002. This intersection of digital archiving and physical hardware preservation keeps real arcade machines running globally without relying on degrading physical media. 6. Digital Preservation and Legal Status
If you own original Naomi hardware and use a NetDimm, you will look for specific decrypted files designed to be sent over a network to the arcade board. How to Use Naomi 2 ROMs
