...after many attempts at dumping the gd-rom from the arcade machine....we were able to get the 908Megs of info dumped!!
SURPRISE! it has default.xbe

It's just an xbox game!! made x-iso with Q-wix... and booted straight up!!

... the funny thing is that in the crazy taxi III dump... they have "back" button as coin button... lol... just like mame... it uses the triggers and d-pad just like the retail xbox version does... plays fine from hdd/avalaunch, service switch is start button.

Not entirely surprising considering Chihiro is the arcade version of Xbox. They're just using a GD-ROM because it is cheaper than a ROM board. The thing is, most arcade units with GD-ROMs only use the GD-ROM at power up to load the game into inexpensive RAM (once per day, essentially).

If this *does* run on a standard Xbox, that means they're using either a HD or the GD-ROM for streaming data as needed. Sega has never used the GD-ROM like that before, because an optical drive will just burn itself out after a while of constant use. HDs are better, but they still don't have the longevity you usually want in an arcade unit. So I don't know what to make of this without more info.
