This script installs the latest GE-Proton, installs NonSteamLaunchers under one unique Proton prefix folder in your compatdata folder path called "NonSteamLaunchers" and adds them to your Steam Library. It will also add the games automatically on every steam restart. So you can use them on Desktop or in Game Mode.

• Automatic installation of the most popular launchers in your Steam Deck 🎮
• Handle automatically the download and installation of your chosen launchers and the games ⌚️
• MicroSD Support 💾 This script supports moving the entire prefix to a microSD. The script will install launchers and games to your SD card, and the launchers in Steam will point to the SD card installation. This allows you to save internal storage space on your Steam Deck!

"NSLGameScanner.service" is also live when you use this script and continues after the script is closed and even works after your Steam Deck has restarted. This works in the background as a service file to automatically add your games to your library on every Steam restart. Currently adds:

• Ubisoft Connect 🎮
• EA App 🎮
• Gog Galaxy 🎮
• Battle.net 🎮
• Amazon games 🎮

• Go to desktop mode, right click the download button above and save the .desktop file to your Steam Deck desktop.
• Go to your desktop, click the NonSteamLaunchers icon, it will download and run the latest NonSteamLaunchers.sh from this repository and run it.
• You will simply have to choose which launcher to install and let the script handle the rest. 💻 No files are left in your "Downloads" they are deleted after installation.
• After running the script, launch Steam on your Steam Deck. You'll find the new launchers in your library under the non-steam tab. Click a launcher to see your installed games from that store, and launch them directly from Steam! If you have downloaded a game inside of your launcher, restart your deck or steam adn the NSLGameScanner.service should add it to your library. Even in gamemode 🥳

Install Docker. Once installed, a clean dev environment with a Docker container native to VSCode is spun up automatically.

• Command palette (⇧⌘P) > Dev Containers: Reopen in Container
• F5 for debug
  • May need to select interpreter (e.g., /opt/venv/bin/python) first

VSCode Extensions (Dev Container)

• Atom Keymap
• Bash IDE
• Better Comments
• Docker
• EditorConfig
• GitHub Copilot
• GitHub Copilot Chat
• gitignore
• GitLens
• Markdown All in One
• MS Visual Studio Live Share
• Python
• Shellcheck

If VSCode isn't present or only the python portion (cf. __init__.py) is being worked on, it's possible to just run a Docker container on its own. The container installs the correct version of python and any dependencies (e.g., ipython, rich) in requirements.txt.

# navigate to directory with Dockerfile
cd .devcontainer/

# build image
docker build -t nonsteamlaunchers .

# run container
docker run -it --rm --name=mynonsteamlaunchers --workdir=/app -v $(pwd):/app nonsteamlaunchers bash

# exit container
exit

Useful for the python module(s), but extra compared to the dev container portion that covers the core shell script.

# create virtual environment
python -m venv .venv

# activate virtual environment
source .venv/bin/activate

# install dependencies
python -m pip install -r requirements.txt 

Additional tooling includes but is not limited to:

• Install asdf
• Usage

  # add python plugin
  asdf plugin-add python
  
  # install stable python
  asdf install python <latest|3.11.4>
  
  # set stable to system python
  asdf global python latest
  
  # add poetry asdf plugin
  asdf plugin-add poetry https://github.com/asdf-community/asdf-poetry.git
  
  # install latest version via asdf
  asdf install poetry <latest|1.5.1>
  
  # set latest version as default
  asdf global poetry latest

.shellcheckrc excludes various bash language rules. Useful to control noise vs. legitimate warnings/errors when using the shellcheck extension.
