Good news everyone.
Until this week, I've just been working with the files I've extracted from Saints Row 2.
Recently, I also successfully extracted all of the Saints Row data files - No textures though :(
Just this minute I have extracted the files from the DLC, including the audio files.
Unfortunately, texture extraction for xbox files has not yet been perfected, so I don't have access to those. But hopefully one day someone will crack it.
I should probably note that I am standing on the shoulders of giants. One person who worked out how to extract files from DLC containers, another who worked out how to extract files from Volition's containers, and a third who worked out how to extract audio from the XWB containers.
It is thanks to these people that I can make this wiki a better resource for everyone. :)
