Quite possibly the best way to install third party launchers onto your Steam Deck, whether it be Ubisoft Connect or the Epic Games Store, is the NonSteamLaunchers script. The script, which was created by moraroy, automatically downloads whichever launcher (and some streaming sites), downloads the latest Proton GE, installs all of it, adds it to Steam, and gives it a custom controller configuration. It all works extremely well, and it's one of my favorite ways to download and install launchers. Now, a new update is here, and it fixes some issues that were present if you have EmuDeck installed, too.

From the last update, there were some incompatibilities with EmuDeck and Steam Rom Manager specifically, but with the newest update, there should no longer be any errors! You may need to get rid of the previous NonSteamLauncher shortcuts so that the new version can remake them (no data should be lost). There were also some bugs fixed with shortcuts, Battle.net will install correctly, and some moe code was optimized (huzzah!) We also have a better backup system for shortcuts with dated timestamps.

You can update NonSteamLaunchers by either downloading the new version from the GitHub page or running the program to auto update!
