When attempting to launch the port with this guide, you will receive an "Entry Point Not Found" error message. I don't know how to fix this and I will leave this guide up for anyone who thinks they can. If someone does manage to fix this I would greatly appreciate knowing how you did so I can update this guide.

First you need to download the source port from: https://icculus.org/rott/



When you get to the site, scroll down to the Windows Binaries section and click ZIP to download the zip file for windows.
The zip contains: rott - darkwar.exe as well as an exe for The Hunt Begins.

You can also use this page to download a Linux version under the Stable Release section.

Next you will need to go to here https://github.com/libsdl-org/SDL/releases/ to get some necessary SDL files.



Download the most recent release of "SDL2" that ends with "x86"
DO NOT DOWNLOAD THE 64 BIT VERSION! (x64) It will cause the game to crash.
You should now have the file: SDL2.dll

After that, go to here https://github.com/libsdl-org/SDL_mixer/releases/



Once again, download the most recent release of "SDL2_mixer" that ends with "x86"
DO NOT DOWNLOAD THE 64 BIT VERSION! (x64) It will cause the game to crash.
You should now have the file: SDL2_mixer.dll

Finally, you need to take the SDL2.dll, SDL2_mixer.dll, and the rott - darkwar.exe and drop them into your Rise of the Triad Dark War folder

...Steam/steamlibrary/steamapps/common/rise of the triad dark war/rise of the triad - dark war

Thats it! Just run rott - darkwar.exe to launch the game.
