Hello,

I tried searching the forums with no luck. I have installed and ran X-Wing Alliance on both a Win 7 desktop and a Windows 10 desktop with the same problem. The game loads up fine, I can go to briefing stage and select mission, but when mission launches the graphics all go a purple color and my screen gets cut in half to where the game only takes up one half of my monitor. I have the exact same problem on both desktops. Desktop 1- Win 7 64bit, AMD processor and AMD R9 270 X video card. Second desktop- Intel i7 6700k processor, AMD RX480 graphics card. Any help would be appreciated. I have run both in administrator mode and compatibility mode for Windows XP servie pack 3, run in 256 colors, etc., nothing helps. Still cuts my sceen in half and everything goes purple on both desktops, so strange. Any thoughts? I'm using the most recent GOG version.

Thanks!

Be sure catalyst isn't changing any graphics settings.

Try windows 98 compatibility mode.

Try starting the game, hold ctrl+shift+escape, go to processes tab, find and click Explorer, (not iexplorer), click end process, then alt+tab back to your game. If you do this, just go back to task manager and click the applications tab, click new task, then type "explorer" and hit enter.

Let us know if their don't work.

Good luck!

Does it look like this?

The game comes with a wrapper (ddraw.dll located in the game folder).
Apparently GOG modified the game in some way that causes graphics corruption if you play the game without that wrapper or with a different one like dgVoodoo. (This doesn't happen with the original game released on CD-Rom.)

So if you're getting that issue the ddraw.dll is probably missing or the game is not using it for some reason, maybe due to interference by antivirus software. Though I don't know how two systems could be affected at the same time.

Reinstalling the game might fix it or you could download the original ddraw.dll from here: https://github.com/JeremyAnsel/xwa_ddraw_d3d11/releases

You might also want to try this updated version.

PS: If you run the game with 3D hardware acceleration enabled, image corruption should only be present on the loading screen but not in flightmode.

EDIT: Those changes can be undone using XWA Hacker and the 16bitmode.bat.

See readme for usage.

Yep, that's it! Looks just like those pictures. I really appreciate the responses and help, but I got so frustrated trying to get it to work I just gave up and on a whim bought the Steam version during the sale for about $3 and you guessed it, it works flawlessly (surprisingly). After installing XWA Upgrade the game is a beauty!! I don't mind buying this game twice, it deserves every penny. Thanks again for the responses!

I've also had the same issues with GOG's XWA, and nothing suggested work... or even seemed to want to work. XWA Hacker refuses to run on my computer, and all that the ddraw.dll did was make the game refuse to load at all.

For the record, I'm using Win XP Pro w/ System Pack 3, AMD Athlon 64 X2 Dual Core Processor 4400+, and Nvidia GeForce 7800 GT video card.

The ddraw.dll needs DirectX 11, so it's not compatible with XP.

This older version of XWA Hacker should work:

Oh, do newer versions of XWA Hacker not work on XP? What is the problem?
What about the GUI versions?
There is no real reason why they shouldn't run even on Win98 or so, I just can't really test it myself.

EDIT: Up to 2.3 works fine, and all GUI versions are fine, too.
I likely found the cause, so I expect future versions will start working on WinXP again, too.
