Bink2 videos just stored as plain text.


Unfortunatelly the XTool Bink video plugin will not work here for "GUS_CGI01_Part2.bk2". I tested both versions of the plugin and get extraction errors, not matter what settings I use (c/--diff).

For "GUS_CGI01_Part2.bk2" you can go the old way of manually patching. The diff file is 15.1mb.

You can unpack the file with the above modified bms script. Just make sure you null the entire stream in "Data\Gustav_Video.pak" before making the repack and don't forget to patch the file back after installing with either xtool or quickbms.

So basically extract "GUS_CGI01_Part2.bk2" out of the file and patch the entire stream out. Manually make a diff file for it and for the modified "Gustav_Video.pak" use XTool bink plugin.

As for the audio files, they contain wem's, but wemtool can't do anything here.
