All of them, including Doom 64. I bought Doom (2016) on switch mostly for a laugh but it’s surprisingly playable. Never tried Doom Eternal though.

Definitely recommend customising plasma per the above advice.

I’ve done the same thing with my steam deck (with White Sur theme) and it’s flexible enough to get fairly close.

Until recently I ran a similar setup with latte-dock on my work laptop and but it’s not worth the hassle - it’s buggy and unmaintained, so I swapped back to icon only task manager.

I’d be interested to know if you use any bindings/plugins for Renoise with steamdeck controls.

I use a headless M8 and run https://derkyjadex.github.io/M8WebDisplay/ in Edge (with launch options for game mode). But I didn’t really put in the effort to try and make Renoise work without a keyboard/mouse.

I have Tyrian 2000 on GOG as well and was feeling nostalgic. I could replicate the issues and here’s what I did to fix it.

• Installed the game with Heroic and added it (automatically) to Steam.
• Applied a community control layout named “Tyrian” to fix the mapping issue.
• Launched the game from Steam and used the onscreen keyboard to press 3 to go to “Game DOS settings”. I had to run it twice before the controls worked for some reason. Change the music device to “FM Sound” (I think the default was “Midi 330h”) and saved.
• Returned to the launch menu and pressed 1 to launch Tyrian 2000.

I usually like running DOS games in EmuDeck/Retroarch though.
