I found an off brand adaptor on ali-express that works just fine. It was about $20. Thanks for everyones help.
I bought an Xbox One controller to use with my PC. It is a first generation controller that requires the wireless adapter to connect to a PC. This is annoying as it will cost me about the same price as a new controller ($40). This is a multi-tier question, as I am trying to find the best cost-ratio solution. For now I am playing via USB.
Question 1: Is there a Bluetooth hack for the first gen wireless controllers so I do not need to buy the proprietary adapter?
Question 2: Can the proprietary wireless adapter receive input from more than 1 controller? If so, I might as well buy a second first gen that has the adapter included and I'll have a second controller for player 2.
