The Complete Guide to SEGA NAOMI Emulation: Configuring the bios/dc/naomi.zip File
To make NAOMI games functional, the BIOS files must be mapped accurately depending on your emulation frontend. The table below outlines the exact target folders for the most popular emulation setups: Frontend / Emulator Required BIOS Filename Exact Directory Path naomi.zip RetroArch/system/dc/ Flycast (Standalone) naomi.zip Flycast/data/ or main app folder EmuDeck (Steam Deck) naomi.zip Emulation/bios/dc/ Batocera Linux naomi.zip /userdata/bios/ (or inside /dc/ subfolder) Verification Check: MAME Romset Sourcing bios dc naomizip
When emulating NAOMI or NAOMI 2 games via platforms like RetroArch (using the core) or standalone emulators in frontends like Batocera , RetroBat , or EmuDeck , the system looks inside a dedicated Sega Dreamcast ( dc ) directory for a compressed archive named naomi.zip . Inside the Zip: Why It Matters
The BIOS is essentially the software that initializes the console's hardware and provides basic input/output services. For NAOMI emulation, naomi.zip (from the MAME project) is the standard file used to boot games like Crazy Taxi , Virtua Fighter 4 , Marvel vs. Capcom 2 , and The House of the Dead 2 .

The naomi.zip file should ideally come from a recent MAME romset to ensure compatibility. Depending on the specific system you are emulating, you may also need: : Required for Naomi 2 hardware. naomigd.zip : Required for running GDI (disc-based) games. awbios.zip : Required for Sammy Atomiswave arcade games.
By understanding that the BIOS is the essential firmware that allows emulation to work, and by following the simple steps of creating a dc folder in your RetroArch system directory and placing naomi.zip and any required game-specific BIOS files inside, you can banish emulation errors for good.

A special mention must be made for the hardware. This was a more powerful upgrade to the original NAOMI board, featuring dual PowerVR 2 GPUs and a faster CPU to run games like Virtua Fighter 4 and Initial D .
