I’ve tried x86_64 stable 5.26 and beta 5.27 (20200817) with the same result. I am able to discovers my gamestream box, pair it and get the game list. However, each time I try to start a game, it is only displayed on the gamestream computer. My Batocera computer remains with a black screen.
Has anyone else been able to get Moonlight working with x86_64?
