WINEDLLOVERRIDES='winmm.dll=n,b' %command%
Mouse Y Axis hat to be un-inverted in game settings
Switch to the older Proton version was mandatory for me. Hard system freezes otherwise. I used Deck Forces II as a layout.
WINEDLLOVERRIDES='winmm.dll=n,b' %command%
Changed L4 to Action Set that duplicates the default controls, and inverts the mouse for the Right Joystick
In game vertical mouse controls are Inverted. Mouse can not be inverted within game's options menu. Inverting the joystick will fix the issue in game, and invert the controls in menus.
Vertical mouse movement is for some reason opposite in game versus while in menu, I recommend using an unused key to Toggle an Action set that copies all the keys and inverts the mouse vertical input so you can toggle "Menu Mode" and "Game Mode" as needed as a workaround. This issue applies to both Dark Forces II and Mysteries of the Sith. This doesn't apply to Dark Forces but it may apply to the other Jedi Knight titles (untested)
WINEDLLOVERRIDES='winmm.dll=n,b' %command%
Background music is a known problem for this game. After many hours, I finally discovered a solution. You can use the following launch option: WINEDLLOVERRIDES='winmm.dll=n,b' %command%
Using the Steam version of this game, it boots right away using Proton 7.0-3. You must enable 3d Accelleration in the game settings, and can then select 1280x800. At this point it looks and sounds great, but background music does not work. This has actually been a longstanding problem with the Steam and GOG versions. There are patches and registry edits deisgned to try and fix this, but none of them worked for me. Based on a link provided by another user here, I discovered an easy fix. You can use this command in the launch options: WINEDLLOVERRIDES='winmm.dll=n,b' %command% -- Now music works, and it plays wonderfully.
In order for the actual game to start you need to enable 3D acceleration from the game's graphics options. After that it should run just fine.
