legendary VS steam-rom-manager

You should try using Legendary. It's an open-source command-line client for Epic. It does pretty much what Epic does but it's quicker to install/launch games and you won't have to worry about telemetry or "spyware." Although, you will have to buy games through the Epic online store.

I'm using an open-source alternative to the epic games launcher (legendary) that uses wine, and when i try to run a game through the terminal, a log of wine shows up.

It's an epic games launcher alternative, and a UI frontend for Legendary. (Don't worry, guys. It can launch non-epic games as well 😅) It's simply meant to be like heroic, but this time putting macOS first.

If you are familiar with using the command-line then you can use Legendary and import the game to your EGS, but you will need to do this one by one for each game.

Oh, you're talking about the launcher? Just use Legendary. CLI-based, so performance isn't an issue. If you know how to use a command line, you'll know how to use legendary with no problem. You can even launch some games without ever connecting to Epic after downloading them. Highly recommend, it's what I use.

Hay un launcher alternativo, Legendary. (https://github.com/derrod/legendary). Se usa con comandos (al menos la última vez que lo usé no tenía interfaz). Es.. interesante.

Grab your favorite EGS client and install the game. For this purpose I am using legendary. Legendary is important later, so it is a good idea to have it installed regardless. At this stage, if you try running the game, the game will crash within moments, and spawn 2 windows: a Wine debug window, and a bugsplat window.

If you want to avoid using the Epic Games Launcher, but still want to play the games you have there, you can use Legendary (which requires you to use a command line) or Heroic Games Launcher(which is based on Legengary and has a Graphical User Interface, so is much more user friendly). Both are open source.

Try using an older version os steam rom manager from here. Try 2.4.11. I had a problem where steam rom manager wasn't parsing images and shifting to an older version helped.

That's correct. Thats mainly because steam rom manager exists, but if there's interest I'm happy to look into including non steam games in the "Games" section

It never worked so greatly to begin with. So try https://github.com/SteamGridDB/steam-rom-manager instead that happens to be actively developed and updated just today.
