Ive extracted the tar and ftpd it onto my XBXOX - I only got 4 files from the .tar archive:

bgm.afs
default.xbe
movie.afs
root.olk

They total around 950mb in size......but when I try to launch the game my XBOX just flicks back to the dashboard. Are there some files missing or do I need to extract the non-xbe files further or something ?

Cheers
