Chihiro is an Xbox based arcade motherboard from SEGA

A Chihiro system consists of network board, media board, base board & Xbox board

The whole system is divided into 2 parts and each part has two boards.

The upper part contains a media board with a TSOP48 where there is an xbox .xbe loader

(this is the dashboard you see when you power the Chihiro) and for a network board (100% the same

as the one in the Triforce v3, same firmware also)

The bottom section consists of an Xbox board with 128MB of RAM and with a different MCPX than

a retail one and a base board that handles JVS and Video.

Network Board Dump : Ver1305.bin

Media Board dump : FPR21042_M29W160ET.bin

Base Board Dumps : ic10_g24lc64.bin ic11_24lc024.bin pc20_g24lc64.bin

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.

pc20_g24lc64.bin: it seems a backup of the base board without region or serial, older version maybe?

ic11_24lc024.bin: this is the mysterious one, as the previous 2, its on the Base Board, and just contains some

strings the interesting thing is that it contains the string SBJE and if you go to the system info menu

on the Chihiro and you press service button 16 times in a row, a message will be displayed: GAME ID SBJE

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