How to Add Non-Steam Games on Steam Deck

The Steam Deck, with its Linux-based OS and Proton compatibility, allows you to enjoy non-Steam games seamlessly. Follow these steps to get your favorite titles up and running:

1. Switch to Desktop Mode:
   • Open the Steam app on your Steam Deck.
   • Click the plus sign button in the bottom left corner.
   • Choose “Add a Non-Steam Game” to access your non-Steam library.
2. Locate Your Game Executable:
   • If you’ve installed games from other platforms (like Epic Games or GOG), find the game’s executable file (usually a .exe file).
   • Remember that Linux file paths can be different, so navigate accordingly.
3. Add the Game to Your Library:
   • Select the executable file and add it to your Steam library.
   • Make sure to include all files (not just Linux-specific ones).
4. Enable Proton Compatibility:
   • Right-click the newly added non-Steam game in your library.
   • Go to “Properties.”
   • Under “Compatibility,” enable “Force the use of a specific Steam Play compatibility tool.”
   • Choose your preferred Proton version (Experimental or the latest release).
5. Launch and Enjoy:
   • Re-enter gaming mode.
   • Click the play button for your non-Steam game.
   • Voilà! Your game should boot up as normal on your Steam Deck.
6. Customize Artwork (Optional):
   • To make your non-Steam games blend in with your library, add custom artwork.

Remember, you can repeat this process for multiple non-Steam games. Happy gaming on your Steam Deck!
