HeroicBashLauncher VS NonSteamLaunchers-On-Steam-Deck

Can you utilize addtosteam.sh with this similar to how heroic did?

I've previously used Heroic Bash Launcher for that. It generates a script that opens the game in exactly the same way Heroic does, and you can then add the script as a non steam game.

The EUREKA moment came from a thread for CIV IV on a random Heroic Launcher Github thread. https://github.com/redromnon/HeroicBashLauncher/issues/38

Works for me with Lutris shortcuts and some native Linux games I have installed. Herioc shortcuts needs an extra step using Heroic Bash Launcher

You're probably better launching through heroic and not directly using proton. This project looks like it might add all your heroic games to steam automatically: https://github.com/redromnon/HeroicBashLauncher

Heroic Bash Launcher

Use Heroic Launcher (find in desktop mode via discover (flatpack)). Install Windows versions to take advantage of Steam/Proton. Sync saves using Heroic Launcher too (be careful the feature is currently in Beta, but working fine for me in D:OS). Install the shortcut in your steam library using Heroic Bash Launcher, job done.

For heroic installed games, i used https://github.com/redromnon/HeroicBashLauncher to add steam shortcuts for individual games.

But for Heroic, afaik you need this, though I am still working on the guide and can't 100% confirm.

May not be as popular as heroic but I use nonsteamlauncher ( https://github.com/moraroy/NonSteamLaunchers-On-Steam-Deck ) and it works fine for me. Follow the instructions or youtube it and its pretty straight forward. Other users have mentioned you will be adding GOG to your steam library (you can just right-click from the desktop mode in the applications area now and select add-to steam) Then you'll go back in to steam mode and launch GOG from there. then it works as normal. Can't attest to cloud saves but since you are just running GOG I'd HOPE it worked, even if you don't need it others may.

Use this utility and install Uplay as a non steam game. You can download all Uplay games there and start them via the launcher.

A week ago I stumbled over this https://github.com/moraroy/NonSteamLaunchers-On-Steam-Deck

It looks daunting but thankfully there's this repo here that made the whole process insanely simple, just install the launcher, install the game, and then play https://github.com/moraroy/NonSteamLaunchers-On-Steam-Deck
