Universal Naomi BIOS

Is there a universal Naomi 1 BIOS yet? Ive read some old threads saying it was never done, but then I seen some stuff on google saying the 21576H JPN version is universal but will show the wrong text if you want to play a USA game? I was going to make myself a "universal" BIOS by creating a 3 socket PCB that holds all three chips and a switch (or 2 socket with JPN and USA on it), but I didnt want to waste my time if its already done in one chip?

Never heard of or seen a "universal" bios for NAOMI.

The newest JPN bioses are great for compatibility, but yes, you will have Japanese text on some places in some games that would otherwise be in english. I.E. assist type select in MvC2.

I have seen people wire in 2 bios with a switch.
