If you can help with the undumped games or know of missing Chihiro games, please contact...
http://guru.mameworld.info/  or  http://www.mamedev.org

A Chihiro system consists of several boards.
The system is in 2 separate metal boxes that fit together to form one box.
In order from top to bottom they are....
 - Network board  \
 - Media board    /  Together in the top box

 - Base board     \
 - Xbox board     /  Together in the bottom box

The 2 boxes join together via the Base Board upper connector and Media Board lower connector.

The Microsoft-manufactured XBox board is the lowest board. It's mostly the same as the V1 XBox retail
board with the exception that it has 128MB of RAM and a NVidia MCPX X2 chip. The retail XBox board has a
MCPX X3 chip. The board was probably released to Sega very early in development and the chip was updated
in the mass-produced retail version.

The Sega-manufactured base board is connected to the XBox board via a 40 pin 80-wire flat cable and a 16
pin 16-wire flat cable connects to the LPC header, plus a couple of thin multi-wire cables which join to the
XBox game controller ports (USB1.1) and front panel connector.
On the reverse side of that board are the power output connectors going to the XBox board and a 100 pin
connector where the media board plugs in. A CR2032 coin battery is also located there and next to it are 6
jumpers....
JP3S 2-3 \
JP4S 1-2 |
JP5S 1-2 |
JP6S 2-3 | These are connected to the USB chip on the other side of this board
JP7S 1-2 |
JP8S 2-3 /
A long connector on one edge connects to the filter board (power supply input etc) and on another edge are
connectors for VGA output, audio/video input (from a short cable coming from the A/V connector on the XBox board)
and a 14 pin connector which is unused. The base board handles JVS and video output.

The upper part contains a Sega-manufactured media board with a TSOP48 flash ROM containing an xbox .xbe loader
(this is the Chihiro logo you see when you power the Chihiro) and there's a connector for a Sega network board.
The network board is 100% the same as the one in the Triforce v3 with the same firmware also.

The system requires one of the various Sega JVS I/O boards to operate.

ROMs on the boards
------------------
Network Board : One ST 29W160ET 2M x8-bit TSOP48 Flash ROM stamped 'FPR24036' at location IC2
Media Board   : One ST 29W160ET 2M x8-bit TSOP48 Flash ROM stamped 'FPR24042' at location IC8
                As in Triforce, it consists of two versions in the same flash, the first MB of the flash has
                an older version as backup, and the second MB has the current version, versions included are:
                SegaBoot Ver.2.00.0 Build:Feb  7 2003 12:28:30
                SegaBoot Ver.2.13.0 Build:Mar  3 2005 17:03:15
Base Board    : Two Microchip 24LC64 64k Serial EEPROMs at locations IC32 and IC10
                One Microchip 24LC24 2k Serial EEPROM at location IC11
                The chip at IC32 seems to be a backup of the base board firmware without region or serial.
                The chip at IC11 has an unknown purpose. It contains some strings. The interesting thing is that it
                contains the string SBJE. If you go to the system info menu and press the service button 16 times in a row
                a message will be displayed: GAME ID SBJE
                The chip at IC10 contains the firmware of the Base Board, serial number and REGION of the whole system.
                The region is located at offset 0x00001F10. 01 is JAPAN, 02 is USA, 03 is EXPORT. If you want to change
                the region of your Chihiro unit just change this byte.
                Alternatively, if you have a netboot PIC, plug that in and power up with it.
                 1) Enter the test menu (push the test button)
                 2) Go to the System Information menu.
                 3) Press the Service button 30 times in a row and a hidden menu will appear to change the region.
                 4) Once the region is changed, exit from the menus and after the Chihiro reboots, power off the system and
                    power on again.
Xbox Board    : One Macronix 29F040TC-90 512k x8-bit TSOP32 Flash ROM at location U7D1

Xbox Board Dump    : Not dumped

FPR21042_M29W160ET.bin :
As in Triforce, it consists of two versions in the same flash, the first MB of the flash has
an older version as backup, and the second MB has the current version, versions included are:
SegaBoot Ver.2.00.0 Build:Feb  7 2003 12:28:30
SegaBoot Ver.2.13.0 Build:Mar  3 2005 17:03:15

ic10_g24lc64.bin: This dump contains the firmware of the Base Board, serial number and REGION of the whole system
Region is located at Offset 0x00001F10 , 01 means JAP, 02 Means USA, 03 Means EXPORT, if you
want to change the region of your Chihiro Board, just change this byte.

Thanks to Alex, Mr Mudkips, and Philip Burke for this info.
