Using the Heroic Launcher - marvin1099/wemod-launcher GitHub Wiki

Since the heroic wont support a command prefix like Lutris is doing,
You will need to manually install it for your game.

Firstly follow the Quick Guide to step 6.
After thar you will need to find the game prefix.
To do that in heroic click on the game you like to run with wemod
and open the game settings.
Next click on the tab WINE.
Next copy the WinePrefix folder entry.
Then open the terminal, paste this command,
replace $YOUR-WINE-PREFIX-FOLDER-HERE with the WinePrefix folder and run the edited command:

WINEPREFIX=$YOUR-WINE-PREFIX-FOLDER-HERE WINE=$(whereis wine | awk '{print $2}') /home/$USER/Apps/Games/wemod-launcher/wemod $(whereis wine | awk '{print $2}') /home/$USER/Apps/Games/wemod-launcher/wemod.bat

Keep in mind that the paths /home/$USER/Apps/Games/wemod-launcher/wemod
and /home/$USER/Apps/Games/wemod-launcher/wemod.bat
Might have to be changed if you have installed WeMod to a custom location.

After that select no to the copy prefix question if it says it might work
If it says it likely works skip the next entry.
Select download.
Select Yes/Ok until no more windows appear.
All rundll32.exe errors can safely be ignored (click on no here).
WeMod will start as well as 3 cmd windows.
Close all of the opened windows.
WeMod will go into the system tray after you close it.
So right click on the WeMod symbol in the system tray and click exit.

After that go to game settings and open the ADVANCED tab.
Next click on the folder icon on the left of the Select EXE box,
that is under the text Select an alternative EXE to run.
Then this will open the game path, so then copy the path to the game exe file.

The path may look like this:

/mnt/Standart-Festplatte/Marvin/Games/Heroic/Forager/Forager.exe

This will need to be modified replace any / by \, add "Z: at the beginning and " at the end.
At this point it will look like something like this:

"Z:\mnt\Standart-Festplatte\Marvin\Games\Heroic\Forager\Forager.exe"

At this point change the Select an alternative EXE to run to:

/home/$USER/Apps/Games/wemod-launcher/wemod.bat

And add the modified game path as Game arguments (at the start if you have some args already).
At this point when you start the game wemod should start with it.
