As far as controls go, use the steam input to remap whatever controller you have to the games native keyboard inputs to your liking.

When it comes to dosbox, I’m not sure what you can do but I believe I read that steam has a native Linux platform for some of those older platforms like dosbox. Maybe that could alleviate the sound issues?

That sounds like an awesome gain for the teamsters. Amazing job by their nogatiating team.

Well, it’s interesting. I’d try streaming to the steam deck while it’s in desktop mode and see if that fixes the display issue. Kinda cool that it holds a 800p resolution but I find it curious that it’s not full screen as opposed to the actual 800p but just in the corner.

Did you try doing it while in desktop mode? Game mode defaults to the steam deck native resolution but that can be overriden with launch setting changes. Desktop mode will output to the display of the external monitor.

StarCraft?
