First, you'll need to download one of these GZDoom builds here: http://devbuilds.drdteam.org/gzdoom/

After that, extract it to a folder and place any doom wad/wads you wish in the same folder. Then you want to download this: https://github.com/alexey-lysiuk/tools/ ... fi/Release

Place it in the folder you extracted GZDoom and drag and drop the gzdoom.exe file on the wtfi.exe file:

A window will open and quickly ask you to press any key to continue, do it! There you go, you now have a working/patched version of GZDoom!

:bfg: :angel:

So, a little update here, you don't need to use one of the GZDoom builds mentioned earlier, you can use the latest GZDoom update (v2.2.0) too: https://gzdoom.drdteam.org/page.php?page=download
Just make sure you download the 32-bit one, I have a 64-bit system but the 64-bit one doesn't seem to work, okay?

This may or may not need some form of addressing for those who use ZDL.exe. Just saying. I don't personally have this problem, but it wouldn't hurt to provide a workaround for those who use launchers. (I would say if I knew of a good workaround myself, but I do not.)

wtfi.exe is a patcher tool that rewrites the manifest. It only needs to be run once (per devbuild/release) on the .exe and then ZDL will launch it just fine.

Works for EDuke32 as well though you have to select the .exe file manually.

It works, but with some mods cause gzdoom go on background (mouse cursor appears and music is still playing).
Is there any solution for this problem?
