there's a default nvram file in the romset with the magic byte set, although you MIGHT have to byteswap that file to program it into hardware, MAME output byteswapped files for many years so a lot of the default nv files in the romsets are byteswapped.
but yes, for this game you need that magic byte in eeprom, it's security, the code clearly wants it there.
