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?
Thank You,
DFL
