How to get controller working with non-Steam game, Metal Gear Solid (GOG)?
I just bought MGS and imported it to Steam. I want to play it using Steam Link on the OSMC television, using an Xbox 360 controller.

The controller works when plugged directly into the computer when launching the game through Steam.

However, when the controller is plugged into the OSMC running Steam Link, the game does not talk with the controller.

Is this an issue with the game's controller compatibility? Why isn't it communicating with the controller through Steam Link?
