As a long-time fan of classic games and someone who recently got myself a Steam Deck, I was thrilled to discover that it’s possible to run the GOG Galaxy launcher and play my beloved library of games on this handheld powerhouse. Following these instructions, I was able to install and use the NonSteamLaunchers plugin with Decky Loader to add GOG to my Steam Deck’s library.


GOG, or Good Old Games, is much like the Steam Store, offering a vast collection of classic video games. Although it isn’t originally compatible with the Steam Deck, you can use Decky Loader to operate the GOG Galaxy launcher in Steam Deck’s Gaming Mode and download your preferred titles from GOG.

As a seasoned gamer with a penchant for exploring alternative gaming platforms, I’m thrilled to share my experience on how to run GOG Galaxy games on the Steam Deck using the Decky Loader. The ability to install and use unofficial software like NonSteamLauncher opens up a whole new world of gaming possibilities.
