Find ways to run GOG Galaxy on SteamDeck.
It turned out to be much simpler than I thought. The main steps were: start the installer by connecting it to Steam as a non-steam title, set the compatibility settings to require Steam’s Proton features, and then tell Steam to run the already-installed .exe instead of the installer. The same approach also works for Battle.net, though I included the full instructions here.
