Game launches and I'm able to see the intro movies, but the menu is just black. The cursor shows up and I can hear the music.
edit the swkotor.ini file next to the game binary and set the game to a __windowed 4:3__ resolution like __800x600__.
This fixed your problem for me. I played for a very short time but the game ran perfectly
Tried that (800x600) and then the top half of the game was clipped outside the screen for some reason. I then tried 1280x1024 and that loaded ok and after restarting, the mouse and everything worked great.
Just to avoid people having to search everywhere how to put the game in windowed mode.
Add to the swkotor.ini file under the [Graphics Options] section :
RefreshRate=60
Height=1024
Width=1280
And change FullScreen=1 to FullScreen=0
This is actually an issue in Windows too. Everything else works perfectly, so this should be ready for a whitelist request.
In my case I had to set
EnableHardwareMouse=0
as well to get the mouse cursor to line up with buttons. But still sometimes it won't line up perfectly with buttons or dialog options.
And videos play for me only very small (probably their original resolution) in the top left corner.
Installing the game through Lutris works perfectly, though. I think it is because there wine actually does a modeswitch to the proper resolution.
I can't play this game, because the game auto closes after hero select and the game loading.

Game is playable for me once I changed the settings in swkotor.ini to window mode. However the mouse doesn't exactly line up with menu options when scrolling down them using the mouse. (the cursor is always a little below the selected menu option) Also I hope support for this game could be fixed to give it higher resolutions for the sake of fullscreen mode.
I really hope this gets fixed. As a temporary solution I've decided to run this game through the windows version of steam under a pure wine prefix so I'm able to play the game in fullscreen.
Game crashes when loading a save game (same as MikaelBox)
Discovered a better fix for the screen issue. The latest version of the fork here fixes it. https://github.com/GloriousEggroll/proton-ge-custom/releases/tag/5.11-GE-1-MF If the differences can be checked out and merged that'd be awesome.
Edit: Played for a good couple of hours or so. No issues with it other than having the active character freeze sometimes and having to switch to another in the party to get around but I'm pretty sure it's also a Windows bug so needless to say the GloriousEggRoll fork made my weekend. I really hope the main proton gets to this point as well. Oh also I suspect the fork is doing automatically what I used to do manually which is changing my screen res and then changing it back when I exit the game. I suspect this because I noticed the icons on my desktop got moved to the top left corner of the screen and I think it happened after playing but honestly IMO it's a very small price to pay.
Just upgraded to Ubuntu 20.04 LTS and now I am getting this error:

EDIT: I was on Proton 4.2-9 before, and then upgraded to 5.0-9. I downgraded back to 4.2-9 and the launcher is working again.

I tried this, however, I am now getting this error:

I upgraded my drivers and changed it back to 5.0-9 and now it's working!
