Here's a video of it working. Ignore my really bad takeoff
- I added the installer itself as a non-steam app to get the Steamdeck to launch it via proton. I then added the game as another steam app.
- If you name the game exactly "Condor 2: The Complete Soaring Simulator", the steamgrid CLI tool should be able to auto-download the images from Steamgrid (see first link above). Steam might also auto-find my shared controller config this way.
- I changed the mouse setting to allow the mouse to control the camera without clicking.
- There's an error message when you start the game (see video) but it doesn't seem to matter.
