Steam Deck support


Installing our mod on a Steam Deck requires some extra steps beyond the standard manual installation process. And there are also a few recommendations that we would like to share.

Our recommendations are based on our own experiences, which we also wrote about in this blog post.

In short, the steps look like this:

  • Switch to desktop mode on your Steam Deck.
  • Prepare the mod archives and the OwlcatModificationManagerSettings.json file by downloading or copying them from your desktop.
    Do not create the settings file from scratch on your Steam Deck!
  • Use Dolphin (the file explorer) or Konsole (the console) to extract and copy all the files to the correct target folder.
  • Start the game and check the mod status: either
    • Press Ctrl + M on a keyboard, if you have one, or
    • Check the game logs to ensure the mods were identified and loaded.
  • All done!

Troubleshooting 101

If the game still does not see your mods after you’ve tried everything (and you’ve definitely extracted the files to the Modifications subdirectory, right?), the problem is definitely a missing quote, a misplaced space, or a stray character in the OwlcatModificationManagerSettings.json file or its name.

Just download* this valid settings file and copy it to your Steam Deck.

* Right-click on the link in your browser and select “Save link as…"

Switch to desktop mode

  1. First, press the Steam button and select Power -> Switch to Desktop:
Switching to desktop mode
You can also access the submenu by holding down the power button.
  1. After a couple of seconds, your Steam Deck should switch to desktop mode:
First look at the SteamOS desktop
Everything goes according to plan.

Prepare the files

Now you'll have to prepare the mod archives and the OwlcatModificationManagerSettings.json file before placing them in the target folder.

Download the mod archives that you want to install or copy them from your desktop to the Steam Deck using a flash card, USB stick with a Type-C adapter, Warpinator, etc.

For simplicity's sake, let's presume that you've placed the mod archives and the settings file in the Downloads folder:

Let's place the files in the Download folder
Let the files hit the folder.

How to prepare the mod settings file

DO NOT TRY TO CREATE THE MOD SETTINGS FILE FROM SCRATCH ON YOUR STEAM DECK.

Most of the failed attempts of installing our mod on a Steam Deck were caused by a missing quote, a misplaced space, or a stray character in the OwlcatModificationManagerSettings.json file or its name.

Transfer a valid settings file from your desktop. Or, if you'd prefer, download and save* this settings file that was tested in our post.

* Right-click on the link in your browser and select "Save link as..."

You can also download the basic zipped file from the Files -> Miscellaneous section on Nexus Mods. Extract the file and copy it to your Steam Deck.

What’s next?

Next, we'll have to find our target folder and place our files there:

/home/deck/.steam/steam/steamapps/compatdata/1184370/pfx/drive_c/users/steamuser/AppData/LocalLow/Owlcat Games/Pathfinder Wrath Of The Righteous

You can choose how to do it:

Follow the instructions in the relevant section below.

Place the files (Dolphin)

Follow the instructions in this section if you prefer to manage files visually with Dolphin—the default SteamOS file explorer.

Find Dolphin

First, locate the Dolphin icon. By default, it's attached to the bottom of the screen:

By default, you can find Dolphin on your desktop
Tap the icon.

If it's not there for some reason, you can find it in the System submenu:

As the default file explorer, Dolphin is located in the System submenu.
It will be there.

Go ~home

Click on the Dolphin icon to open the app and select Places -> Home:

Go to the Places -> Home directory
We have to go to the home directory.

View hidden files

Now, we need to see view the hidden files. Click the hamburger menu (three horizontal lines) in the top right corner of the window, then select "Show Hidden Files."

The hamburger menu in the top right corner
Select the "Show Hidden Files" option inside.

At this point, you'll see the previously hidden .steam symlink that we'll have to dive in:

Hidden subfolders emerge
Now you see me.

Let's go deep down the directory tree until we reach our target folder.

Dive to the target folder

Make sure you have installed the game and loaded the main menu at least once.

Our target folder on SteamOS is located precisely here:

/home/deck/.steam/steam/steamapps/compatdata/1184370/pfx/drive_c/users/steamuser/AppData/LocalLow/Owlcat Games/Pathfinder Wrath Of The Righteous

To simplify things, first locate the Steam subfolder where the game is installed.

The Steam ID for Pathfinder: Wrath of the Righteous is 1184370 . We should then follow the chain of the subdirectories:

HOME  -> .steam -> steam -> steamapps -> compatdata -> 1184370
The parent folder for mod settings and saves
One down, one to go.

We are closer to our target folder. However, we'll have to go a bit further...

... -> pfx -> drive_c -> users -> steamuser -> AppData -> LocalLow -> Owlcat Games -> Pathfinder Wrath Of The Righteous
The pfx folder that we have to dive in
We need to go deeper.

... until we reach our final destination:

The parent folder for mod settings and saves
And way down we go.

Place the settings file

We have the folder.

Now, copy the previously prepared OwlcatModificationManagerSettings.json file here:

The settings file should be placed in the target folder first.
The most important step of all.

Create the Modifications subfolder

We also have to create the Modifications subfolder to contain the mods:

It will come into play in the next step.

Extract the mod files

Finally, extract the prepared mod archives and place the mods in the Modifications folder:

This is the parent folder for mod settings and saves
They are finally here.

All done. Now is the time to start WotR and check the mod status.

Place the files (Konsole)

Follow the instructions in this section only if you prefer working with the console and enjoy not making any errors.

For simplicity, we will assume the following in this section:

  • The mod archives and the OwlcatModificationManagerSettings.json file were prepared in the previous step.
  • The prepared files are in the Downloads folder:
Mod archives and the settings file are in the Downloads folder
Note that archive names can vary.

Now, let's copy and extract our prepared files to the target folder:

/home/deck/.steam/steam/steamapps/compatdata/1184370/pfx/drive_c/users/steamuser/AppData/LocalLow/Owlcat Games/Pathfinder Wrath Of The Righteous

The filenames vary depending on the mod archives you have, but the principle remains the same:


#go to the target location
cd "/home/deck/.steam/steam/steamapps/compatdata/1184370/pfx/drive_c/users/steamuser/AppData/LocalLow/Owlcat Games/Pathfinder Wrath Of The Righteous"

#copy the prepared settings file
cp ~/Downloads/OwlcatModificationManagerSettings.json .

#extract the archives to the Modifications subfolder
unzip -q ~/Downloads/GraciousFriendships-0-9-9b.zip -d ./Modifications
unzip -q ~/Downloads/GraciousFriendships_Woljif-0-9-9b.zip -d ./Modifications

All done:

Working in the console
Short and swift.

Check the mod status

With a keyboard for your Steam Deck, you can press Ctrl + M while in the main menu to see enabled mods. If you don't have a keyboard, you will need to check the logs.

Using a keyboard

Connect it to your Steam Deck before starting the game. Press any key when the game prompts to make a selection:

It's time to choose between the keyboard and the Deck controller
You can only pick one, choose wisely.

While in the main menu, press Ctrl + M to open the Owlcat Modifications UI submenu:

The Owlcat Modifications UI
You'll see all the installed and enabled mods.

Using logs

Start the game and wait until the main menu appears. Quit the game, then open GameLogFull.txt, which is located in the same folder we searched for in previous steps.

The logs show that the mod was successfully found and loaded.
If the mod was found, blueprints are loaded.
