added info about region bytes & version numbers.
reordered the BIOS list a little, IE:
  Export
  USA
  Japan

#define ROM_LOAD16_WORD_SWAP_BIOS(bios,name,offset,length,hash) \
ROMX_LOAD(name, offset, length, hash, ROM_GROUPWORD | ROM_BIOS(bios+1)) /* Note '+1' */
/* BIOS info:
Revisions A through C can handle game carts only
Revisions D and later can also handle GD-Rom board
Revisions F and later can also handle GD-Rom board and or the network GD-Rom board
F355 has it's own BIOS (3 screen version) and different JVS I/O Board
Info from roms starting at 0x1ffd60
EPR-21576g - NAOMI BOOT ROM 2001 09/10 1.70 (Japan)
EPR-21577e - NAOMI BOOT ROM 2000 08/25 1.50 (USA)
EPR-21578e - NAOMI BOOT ROM 2000 08/25 1.50 (Export)
EPR-21578d - NAOMI BOOT ROM 1999 06/04 1.40 (Export)
EPR-21578a - NAOMI BOOT ROM 1999 02/15 1.20 (Export)
EPR-21579 - No known dump (Korea)
EPR-21580 - No known dump (Australia)
EPR-22851 - NAOMI BOOT ROM 1999 08/30 1.35 (Multisystem 3 screen)
EPR-21577e & EPR-2178e differ by 7 bytes:
0x53e20 is the region byte (only one region byte)
0x1ffffa-0x1fffff is the BIOS checksum
Region byte encoding is as follows:
0x00 = Japan
0x01 = USA
0x02 = Export
???? = Korea
???? = Australia
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 multi screen boot rom
