Doom64 seems to be stuck in an infinite loop on first launch with Heroic on Steam Deck

[esther]

Doom64 was available for free on the Epic Games store, a few weeks ago so I downloaded it on https://heroicgameslauncher.com/ but it seems to be stuck before getting into the menu.

... after the intro sequence it seemed to not continue beyond the Menu which lists "Start" as the only option. The spinning daemon head is replaced with the white Bethesda cube which seems to spin infinitely.

You missed a window and need to log in to bethesda.net

During installation you should have noted a window popping up. As someone else pointed out. You did not? Me neither, but Discover Software Center popped up suggesting to install Mozilla Firefox. Which is odd, because Firefox was already installed.

Install Firefox as suggested and you will see the login prompt from Epic to bethesda.net on your Steam Deck. I guess this has something to do with Flatpak, which is how I installed Heroic. It seems the game wasn't able to find the browser through all the sandboxing (Wine, Flatpak).

When you have done that you should have no issues with that part anymore.

Add -skipmovies as a start up parameter, as suggested on https://www.protondb.com/app/1148590 . If you absolutely want to avoid creating a bethesda.net account you have too look a bit deeper into the problem I guess or wait about 3 minutes for the program to give up. Startup parameters don't seem to be documented very well or I'm looking in the wrong direction here.

Adding Doom 64 and other games from Heroic to Steam

Install, setup and run https://github.com/redromnon/HeroicBashLauncher/

Saves you time adding them all by hand and picking artwork.

Steam controller layout

WASD and mouse (touchpad) layout worked best for me on Stream Deck when starting Doom 64 from Steam. Using the right stick to look around resulted in terrible stutter and I don't have that much time to investigate further why.

Other games with similar issues

• https://www.reddit.com/r/SteamDeck/comments/xry0sg/runbow_anyone_got_this_free_epic_game_working/ - Epic Games Store or which ever store the game is downloaded from requests some permission, but the mechanism to bring up the browser or a webview does not work reliably, like on Steam Deck with Heroic
