I’ve tried probably 10 times, and only once have I gotten Retroarch to show. It’s strange that the program doesn’t just show all open windows and let me choose. Is there a secret to getting a window to show up? I can get the ctrl+tab menu to load in Retroarch but it’s not showing as a source in my stream. I don’t know what was special about the one time I got it to work. I’ve tried having Retroarch as the only window up when loading but it still didn’t help. Any ideas?
Try to change your source to Any Game. Changing your source is located on the bottom-left corner of the window and select Any Game. This will automatically switch between windows that are running per core/emulator.
