Scan ROM for the text string "LOADING TEST MODE NOW" back up four (4) bytes for the region byte.
NOTE: this doesn't work for the HOTD2 or multi screen boot roms
Dev BIOS v1.2: NAOMI DEVELOP 1999 02/15 1.2
BIOS for games debugging and testing using NAOMI dev.box. Basically it's same as retail BIOSes but have enabled monitor/debugger and does read region code from DSW2/3/4.
BAD_DUMP note: we got only 1st half of ROM, 2nd half was handcrafted from same revision retail BIOS.
Next two BIOSes are likely special tools for dev.box hardware test, repair, reprogram, etc purposes, not 'regular' ones.
Dev BIOS: older version, from about mid November 1998 (some sources call it "NAOMI Test BIOS ROM")
