My new story in the Gamestream Retroarch saga is as follows -
I finally got 2 Gamestream Controllers working.
Suddenly, Retroarch simply will not stream to my Nvidia Shield.
If Retroarch is windowed, I do get a picture, but sound plays on source PC.
If I go fullscreen, or windowed fullscreen, nothing on my Shield TV - everything plays on source PC.
This does not happen with any other emulators.
I have rolled back to my previous working RA build, and it is doing the same thing, when oddly it worked perfectly in the past. Did Nvidia do something in a recent update possibly?
