I have the Guide Button (Xbox Button) assigned to close Retroarch and other emulators, which in theory is the perfect solution to me, especially now that LaunchBox also supports this function too.
Unfortunately this does not work when I start BigBox from inside Steam Big Picture, Steam won't pass through the button press.
Ofc Steam has it's own functionality for the Guide Button, but you can disable the Steam Overlay and then everything should work as usual, at least I think this has worked in the past.
Anyway it doesn't work, anybody knows how to get around this?
(btw. I also disable the Windows Gamebar picking up the Guide Button press)
