How to Update Your Naomi ROMset Properly

If you already have a base set and just need the “upd” (update pack), follow these steps:

  1. Get the latest MAME datfile – From the official MAME releases page.

  3. Download only the changed files – Redump or archive update packs are usually 100–500 MB.
  4. Rebuild – Merge the upd into your main set.

Pro tip: Look for “Naomi rollback ROMs” if you use Fightcade for online play. Those are often updated separately.
