I love streaming PC games to my RetroPie and being able to use my X360 or whatever controller I choose to map. I just set up Dolphin (GameCube) emu to stream through Steam. Is it possible to use a USB or Bluetooth controller via the PI to control the EMU that pulls up on the PC? Or do I have to pair my PS3 controller to PC and just stream the video/audio to Pi and let the PC recognize the gaming inputs?
In this video, https://www.youtube.com/watch?v=3musDxzlhCM , the guy is streaming emulators to his device. He is playing on one screen but his controller is paired to the PC and not to where he is streaming too. Is it possible to stream to device (retropie) and have my paired remote to the Pi to control the emu streaming from steam? Otherwise you would have to be within range of bluetooth to be paired to your PC to play the other PC based emulators.
