So, I got a shiny new Android TV (the 55" Sony Bravia X930D) and am trying to figure out how to get it to work with any of my existing controllers (Steam Controller, XBox One controller, and PS3 controllers) in hopes of playing some RetroArch. RetroArch is unusable / won't respond to the controller, despite whatever controllers I plug in. The TV remote is only capable of one input at a time, so it's totally worthless for any android games. There's no obvious way to add any controllers other than dualshock 4s to the TV (despite Sony listing about half a dozen devices that supposedly work with it.) Is there an (easy?) way to add support for additional devices? Is there some hack or app to add controller support? Also... No Google Chrome or browser preinstalled? WTF?
