Running in SteamOs

[devout finch]

I’m begging you to teach me how

[sand quarry]

copy this file (only this file) to a steam deck and make it a non steam game

before launching the game change compatability mode (in steams game properties) to proton (newest non experimental)
when asked to select directory select literally anything since it's a virtual disk
then the game will start downloading (this is how it's gonna look initially)

once it starts downloading, just exit desktop mode and start the launcher from steamos menu
it should look normal there
