The ddraw.dll and jk.dll from the 2013 patch were designed to work specifically with Jedi Knight, and won't work with Mysteries of the Sith.

As far as I know, there is currently no way of playing Mots with 32bit and corrected vertical view on widescreen. If anyone ever finds a way, please, let us know.

And never forget that the 2008 and 2013 patches were designed to be applied to the 1.0 JK.EXE from the retail CD. Once you have the patched exe, you can use it with the GOG files, and it will work perfectly, including the music.

Also, I only tested this in Windows 8.1, where both the original CD version and the GOG version run the menus perfectly in fullscreen, without need for the -windowgui parameter.
