NonSteamLaunchers - Add alternative launchers to Steam (Battle.net, Epic Games, GOG and more)

This is an absolute fantastic way to setup alternative launchers directly in Steam! I used NonSteamLaunchers-On-Steam-Deck-Repository by moraroy to accomplish that. The name implies that this might be Steam Deck only but its also Arch Linux and gave it a try. To give you a spoiler: "It works flawlessly"

Installation

• Prerequisites To work with GitHub repositories it is essential that you have git and base-devel installed:

pacman -S git base-devel

• Clone the repo and cd into it

git clone https://github.com/moraroy/NonSteamLaunchers-On-Steam-Deck.git
cd NonSteamLaunchers-On-Steam-Deck

Start the installation by executing the provided script. In the GitHub repository there is also an option to just download a .desktop file and launch it that way, but by executing the script in a terminal you’ll see what the script is doing and the overall installation process takes time. At some point the GUI also looks like it crashed but it isn’t the case.

chmod +x ./NonSteamLaunchers.sh # Optional if not already executable
./NonSteamLaunchers.sh

When the main window appears just tick the launchers you want to install and hit OK.

I encourage you to install proton-ge-custom-bin package via AUR because it provides always the latest Proton build by GloriousEggroll.

Add mount points in NonSteam games

For me I download every game from Steam and alternative launchers to a external drive. I found out that there is no easy way to add mount points to a NonSteam game via winecfg. Especially when protontricks do not find the AppID to a NonSteam game. So I decided to write a little script for that problem. Source: https://github.com/anonymouz-trash/Steam-Proton-Manager

Installation

git clone https://github.com/anonymouz-trash/Steam-Proton-Manager.git
cd Steam-Proton-Manager

sudo ln steam-proton-manager.sh /usr/local/bin/steam-proton-manager

You can hard link the script to /usr/local/bin to make it globally available. ;-) In case of updates to the repository the hard linked file will be the exact same as the source. So don’t have to do this step every time.

Usage

USAGE: $0 {"STEAM_COMPAT_DATA_PATH"} {"shortcut"}

Example: $0 /home/$USER/.local/share/Steam/steamapps/compatdata/<appid> winecfg

Hint: Always use absolute paths! The 2nd parameter is optional.

The 2nd paramater can be used as shortcut:
control  = start Control Panel
regedit  = start Regisitry Editor
taskmgr  = start Task Manager
winecfg  = start WINE-Configuration
tricks   = start winetricks
fonts    = Install core (f)onts
vcrun    = Install Visual (C)++ Runtime 2015-2022
dotnet   = Install .(N)ET 4.8

• 1st: Check the AppID in your local “../steamapps/compatdata/” folder

ls -l ~/.local/share/Steam/steamapps/compatdata

lrwxrwxrwx 1 tommy tommy   62 29. Mai 07:38 NonSteamLaunchers -> /home/tommy/.local/share/Steam/steamapps/compatdata/4206469918

There you’ll a file called NonSteamLaunchers. This file is linked to the right folder with digits. That is our wanted folder. Copy the absolute path /home/tommy/.local/share/Steam/steamapps/compatdata/4206469918.

• 2nd: Start my script as shown below

steam-proton-manager /home/tommy/.local/share/Steam/steamapps/compatdata/4206469918 winecfg

This will start the Wine Configuration window where you are able to add mount points via the Drives panel.

The easier way

Just add a symbolic link to the directory you want to mount as a windows drive.

ln -s /path/to/mount/directory /path/to/prefix/dosdevices/d:
