flo VS BoilR

The easiest way to do this is to use Boilr. It supports Lutris and will add your Lutris games to Steam as shortcut automatically (and also download game art from SteamGridDB if you give it an API number). Boilr is also on Flathub so installing it and using it is super super easy.

And the fantastic Boilr

Hi, there's this old thread, and here the link to the tool itself. Hope it works.

For most of them, use Boilr. Sometimes it doesn’t work, or the launcher isn’t supported, then you gotta look up “How to add X launcher games to steam”.

Or Boilr, to automate it.

Can try this https://github.com/boppreh/steamgrid or this one https://github.com/PhilipK/BoilR for art on non steam game needs ur steamgriddb id

You can use BoilR (https://github.com/PhilipK/BoilR) for that, it will scan all of the usual install locations for your games and let you add them to Steam as individual entries.

Update: You can use BoilR (https://github.com/PhilipK/BoilR) to scan for the games installed and add them as individual entries to Steam, thanks to u/RightSaidJames for the tip!

I unfortunately haven't used steam rom manager before. I'll take a look into it if I get some spare time today and update this comment with how to do it. I use an app called BoilR to add my non-steam games and download artwork for them. You can read about it on it's GitHub page. It may be a bit more technical but I like it better since it adds the emulators rather than the games. This so I don't have my steam library filled with duplicates of my games between yuzu stable and yuzu-ea, if that makes sense.
