Hello everybody, first time posting here on Nexusmods! Going to cut right to the point: are there any whitepapers available on the file formats employed by the Dark Souls games (Preferably DSII:SoTFS)? Took a quick look at the install directory and see a bunch of big damn files which look like archives? If anyone can point me to some resources on what is known about the files and resources that would be awesome!
