Windows Vista (sometimes) & 7 (almost always) causes palette corruption with 8bit color games.

Best solution is to end the explorer.exe task before starting the games.

There are scripts out there with the appropriate commands if you want to create a batch file to do it.

hmm which scripts should i look for?something specific ?

I had this same issue until I downloaded the ddraw viewport clear fix on this page: http://www.jkhub.net/project/show.php?projid= … ction=downloads

Works like a charm now.

EDIT: I'm on Windows 7 64-bit and I've also tried this on Windows Vista 64-bit with success.

And you can get great advice in two places.. Massasi Temple, archive and forum of old Jedi Knight games and also on Lucasforums. both have good sources for all ithe info.

Could this ddraw.dll fix other games problems?

The best way to play Jedi Knight is using the new JKE Jedi Knight Enhanced mod set up, it has been perfected thru long and careful work by community members and there is a enhanced texture project underway as well:

the JKE Jedi Knight Enhanced: JKE

Jedi Knight Retextured: JKR

JK Unofficial Patch:

and for the in game settings: these are reccomended for the best graphics, and I welcome any other suggestoins or other set ups that people find good:

1600 x 1200 Resolution (i use up to this)

3D Acceleration check Yes
Enter 32 in to Minmum Texture Size

Back Buffer In System Memory

Increase View Size to Maximum

I've recently played Dark Forces II: Jedi Knight in Win7 x64, and none of the fixes/updates I've tried got rid of the "garbled UI colors" problem on my system, though the game itself works quite well (and even supports widescreen resolutions correctly, which amazed me). The simple fix is to launch the game with the "-windowgui" parameter which makes the UI and videos run in a window. The 3D game engine will still run in fullscreen mode. It's not a perfect solution but it works.

@CrisGer: your links are not correct

Now they are Dominus, sorry about that! Hello to Wein!

Less Bier, more Wein in Wien!

I am sorry about that, my grandmother would be ashamed of me, she was from a small village near Villach.. i appologize for making Wien into Wein.

Thanks for the links (the site is a bit confusing IMO) and for all the Wein 😀

Best solution is to end the explorer.exe task before starting the games.

Here's a better solution. Before playing the game, right click the desktop, and open up the resolution control panel. Don't do anything with it - just leave it open. Then play the game. No more palette corruption.

That doesn't always work. Ending explorer.exe does.

It's worked every single time I've tried it. And every time I recommend that to someone the response is always "Wow, I can't believe that worked!"

Certainly it at least makes sense for anyone with this problem to *try* the resolution control panel method first.

Tried all of the above and i must say that ONLY ADDiCT's -windowgui switch hint works.
Don't know how all these patches and fixes from Jk Hub are supposed to work,
but they only corrupt the Jk.exe. So -windowgui works best.
