This Guide aims to clear up some of the conflicting advice I've read about getting the enhanced edition of Tie Fighter Remastered Working on a modern computer.

I'm Running Windows 10 Home (64 bit) with an Nvidia GPU. Other hardware/OS's may have other issues.

To allow 3D acceleration to work on NVIDIA hardware do the following.

Download the xwing_ddraw_d3d11_1.4.0.zip from (Newer versions will also work)
https://github.com/rdoeffinger/xwa_ddraw_d3d11/releases/latest/
and extract ddraw.dll and ddraw.cfg to the game directory
..\steamapps\common\STAR WARS Tie Fighter\remastered

This will overwrite the original ddraw.dll

Once in the game engine you press "esc" and select "3D acceleration" from the options menu.

If this doesn't work for you please check out the very informative thread here

To get the game running you can just copy winmm.dll from
C:\Windows\SysWOW64
to
steamapps\common\STAR WARS Tie Fighter\remastered\
Overwriting the existing file.


However that does not enable the ingame music. To do this you should download one of these files

http://www.speedyshare.com/nZ8ty/Windows-10-Fix.zip

Open the downloaded ZIP file and open the 64bit folder, then extract the contents of the folder to the game directory.
steamapps\common\STAR WARS X-Wing\remastered\

The next time you start the game In flight music should now work.

Update: I can't remember exactly what was in these files. try this thread instead to get the music working.

Without this launch option I found that the mouse was limited to the top left corner of the screen.

From BigPicture mode:
* Manage game --> Lauch Options
Add
-softwarecursor
Click OK

Assuming you
* have NOT enabled "compatibility mode" on TIE95.exe
* have NOT enabled ""run as administrator" on TIE95.exe
* have launched the game from Bigpicture mode
then the steam overlay should be enabled and so the steam controller should "just work".

If you get prompted for a joystick then the steam overlay isn't working correctly, and so the controller is not being made available to the game. Check the above.
