Call of Duty 2 FastFile Research (Xbox 360)
Work in progress, semi-works at the moment
How to get fastfiles?
Extract Xbox files (e.g DLC) with http://gael360.free.fr/wxPirs.php
Which should give you the fastfiles
You could also try to use https://github.com/rene0/xbox360, but this only gives me content.ff
