Step 1. Verify Integrity of game cache. To do this go into your steam library, right click the game, properties, local files, then verify intergrity of game cache.

Step 2. Go into the games files do this by going to your steam library, right clicking the game, properties, local files, browse game files (or something like that)

Step 3. Delete the Jedi file.

Step 4. Copy and paste a shortcut to the JK.exe file from the games directory to whereever you want it, i.e. the desktop probably.

Step 5. Go into the properties of your shortcut, then to compatability. From here set the game to run as an admin. and set it to run in compatability mode of Windows XP (Service Pack 3)

Step 6. Rename your shortcut to "Dark Forces II" without the quotation marks.

Step 7. Profit. Try out the game. If it works and you can play it then bravo you're done! You can change the games resolution up from 640x480 to 1600x900, but using this method for some reason you can't do 1920x1080. I'm not sure of the reason of this, but the game should be plenty playable and in fullscreen using this method.

Optional steps.

Step 8. If you have an nVidia card you might need to download and install the legacy driver which can be found here: http://www.nvidia.com/object/physx-9.13.0604-legacy-driver.html

Step 9. If the game still won't work then I would recommend trying out Korriban's steam guide which can be found here: https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=382626458

Step 10. If after trying all other steps and you still can't get it to work. Then try mixing and matching the steps from this guide and Korriban's. I'm unable to do that and tell you the perfect combination as just doing the steps found in my guide fixed the game for me.

I'd like to thank some members of the discussion board on this game for showing me the steps to fix it. The steps I listed have been put into the discussion board a lot of times by a lot of different people. I'm just the guy that has decided to put these steps into a guide for easy access to people. So don't thank me if I helped. Thank the community of DKII for being awesome!
