Naomi 1 Bios - Japan H Version
Thanks Gilles
I got this email several weeks back, not sure what to make of it though:
The BIOS roms files listed on your site are incorrect:
Capcom 23511C is the program from Capcom vs SNK (dumped a half size)
EPR-23609B is actually EPR-23605 (Japan)
EPR-21576D (Japan) is actually EPR-21578D (Export)
I have the following verified roms from the MAME set, info from the MAME source:
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-21576e - NAOMI BOOT ROM 2000 08/25 1.50 (Japan)
EPR-21577e - NAOMI BOOT ROM 2000 08/25 1.50 (USA)
EPR-21577d - NAOMI BOOT ROM 1999 06/04 1.40 (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 Ferrari F355)
EPR-21577e & EPR-2178e differ by 7 bytes:
0x53e20 is the region byte (only one region byte)
0x1ffffa-0x1fffff is the BIOS checksum
House of the Dead 2 specific Naomi BIOS roms:
Info from roms starting at 0x1ff060
EPR-21330 - HOUSE OF THE DEAD 2 IPL ROM 1998 11/14 (USA)
EPR-21331 - HOUSE OF THE DEAD 2 IPL ROM 1998 11/14 (Export)
EPR-21330 & EPR-21331 differ by 7 bytes:
0x40000 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
0x?? = Korea
0x?? = 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 HOTD2 or multi screen boot roms
The following Namio2 info:
/* NAOMI2 BIOS:
EPR-23605 - NAOMI BOOT ROM 2001 01/19 1.50
EPR-23607 - NAOMI BOOT ROM 2001 01/19 1.50
EPR-23608 - NAOMI BOOT ROM 2001 01/19 1.50
EPR-2360xB - NAOMI BOOT ROM 2001 09/10 1.70
EPR-23605B, EPR-23607B & EPR-23608B all differ by 8 bytes:
0x0553a0 is the first region byte
0x1ecf40 is a second region byte (value is the same as the first region byte )
0x1fffa-1ffff is the BIOS rom checksum
EPR-23605 & EPR-23605b - Japan (region = 0x00)
EPR-23607 & EPR-23607b - USA (region = 0x01)
EPR-23608 & EPR-23608b - Export (region = 0x02)
*/
You can either find the MAME naomi.zip & naomi2.zip or I can email them to you if you want all the correct & verified files.
