Same here, sort of. I can play in any mode that isn't 3D Accelerated, but I get a black screen with the HUD and crosshair in any 3D Accelerated mode

There is dgVoodoo but it doesn't work well. If it does work there's a hard limit of 30 fps in Jedi Knight using it. In my humble opinion GOG should remove Jedi Knight from the store until there's a fix or patch that fixes both of those things.

I get an error when I try to start a new game. It said something about a video error and it boots me back to the menu

And what might that "an" error be?
Usually it gives you a hint what going wrong.

I'm running Jedi Knight with dgVoodoo, works like a charm.
The only thing I wished for is that the on screen interface could be zoomed to match high resolutions. As it is, it actually is better running it in 800x600, then scaling it.

Anyone have the patches from original post? The links are dead. I tried to run Gog version with dgVoodoo 2 but I hardly hace succeded as every esolution greater than 640x480 results in black screen and lower resolutions have bad aspect ratio.
But You mean the exact gog version, right? Can You help me with setting up dgVoodoo for this?

I am starting to get some results but still not there. The hardware acceleration seems to be working but something is off with aspect ratio. No matter what i do the game does not seem to "fill" whole 4:3 screen - look at the HUD in attached image.

Now i am baffled cause i reinsatleld the game from the scratch and without dgVoodoo on software acceleration I have exactly THE SAME issue... also checked on old PC with win7 and while there the hardware acc. works without dgVooDoo the same problem occurs in each mode.

Yes and ... maybe.
What you see here is a ingame setting. Change the viewsize ingame.

Please check my later posts with screencaps :)

Thank You. When I set it to almost max but not max it fills the screen and still shows HUD. Do You maybe also know where to get those patches that fix music on Win10? Links I found on forum are dead

Until now I had no idea that the music was broken. I have no issues on Windows 11. Also never had any when I was playing on Windows 10.

Over 5 years and still can't get any of this working in Windows 7 or 10.

You can try OpenJDK project:

Oh and on interesting information for everybody, who loves this game.

Here is a German guy, who tries to remake the whole game in modern Unreal Engine:
