What is the best method to stream LaunchBox from Window 10 to an Apple 4K TV? What have you found successful to be able to play games with a controller within Apple TV? I am also to purchasing other options that will run LaunchBox. I currently own several Raspberry Pi 3B's as well. No matter the platform that would allow me to play on our TV, I want the data and game saves in a centralized location and shared across my PC, the TV in the living room and bedroom TV. Thoughts? Suggestions? Thanks!
