Controller Mapping on Steam Beta
28In this "tutorial" I will show you a new Steam's feature which let's you map any Controller's buttons the way you need it.
You can configure old controllers - even those which don't have standard XBOX 360 Controller's buttons - for any kind of games, even those which do not natively support controllers; that is possible because you can bind keyboard keys to controller buttons and levers, all from within Big Picture Overlay. You don't even need to be running Big Picture to use this function, you can just run games in Desktop Mode but using BP's Overlay, which replaces the standard one.
Pause the video when you want to read info at the top of the screen... There are too many options and I don't even understand all of them, but I tried several setups so far, including customizing dead zone and whatnot on analog sticks and the result is really really good.
