Get, EA, Epic Games and more on Steam Deck the easy way

By - | Views: 47,485

There's many different ways to get third-party launchers onto Steam Deck like, EA, Epic Games and many others. Here's one way that does most of the work for you.

A developer has created a GitHub project, with a simple script to download and run that will then download and set up the launchers of your choice - this even includes then adding their shortcuts to Steam. It's a fun idea and for those who prefer adding launchers to Steam directly to use Proton instead of using something like Lutris or Heroic, this can be a nice time saver.

Here's an example on Steam Deck with and pre-loading Diablo 4:

As with any third-party stuff, use at your own risk but I've tested it and it really does work great.

All you need to do is download the script, pop it on your desktop for convience and then run it and it will be self-explanatory when going through it. One Steam quirk I've seen is that the shortcut might not work right away or let you change the compatibility options, just reload Steam if that's the case.

Text Guide:

  • Go to desktop mode, save the .desktop file to your Steam Deck desktop.
  • On your desktop directly open the NonSteamLaunchers file downloaded. This will download what it needs for you.
  • Then when the UI appears, pick what launchers you wish to install.
  • You can then go back into Gaming Mode and find the launchers in the Non-Steam section of your Steam Library.

For people on desktop Linux, it works just as well there, although I've made a pull request for it not to assume "deck" as the username for the Steam shortcut which will ensure it works properly. Until then, you can just adjust the username to match yours in the Properties of the shortcut on Steam in the Launch Options.

This works quite well, but it uses GE-proton-custom I believe to do the installs. It's easy enough to change afterwards though, just by changing the individual compatibility settings from within Steam.

One thing it does well that I wish more tutorials would show when installing non-Steam stuff, is it uses the STEAM_COMPAT_DATA_PATH variable. Very useful for keeping things easy to manage.

I have seen so many tutorials from popular YouTubers that go one step worse even. They show people to add the installer to Steam, then running it, which creates a prefix, and then adding the exe for the launcher to Steam separately, which results in ANOTHER prefix being created. Instead of just, ya know, editing the exe location in the existing entry.

each day that passes, gaming dependence on windows shrink, hopefully faster than it increase...

i mean, steam receive more games per day than they are able to certify for steam deck (they cant even test then fast enough, the speed that the number of verfied,playable and unsuported list grow is slower than the speed that the number of games grow)
that said i dont think we get tons of new stores everyday, but today a lot of stores became easier to install on linux. (or the day that app was made)
