The 21576H Naomi BIOS, burned and tested onto an EPROM and ready for you to install.
The 21576H EPROM is the latest and greatest for Naomi 1, as it is universal and has no country lockouts. Games from all three regions can be played, and text will be in Japanese when the game contains this text. The 21576 indicates Japanese region, the "H" indicates revision H, with full compatibility with DIMMs, NET DIMMs of any software revision, GD-Roms, and link hardware. G was recently updated to H for Dynamite Deka EX/Asian Dynamite capability and other late release cartridge games.
