As a workaround (I assume Cemu/Yuzu is run in gaming mode from Steam):
Press STEAM button Open Controller Settings Edit layout Go to Gyro Select Gyro Behavior -> Directional Pad Choose anything for one of the positions of directional pad. Anything that won’t intefere with using Cemu/Yuzu. I chose Action Sets->Cleared from Parent Now it should work.
That was enough to get Cemu working again. For Yuzu I had to remap the motion sensor. Best way to do that is to follow this video
Do, they work great. I just got around to adding some switch games to yuzu yesterday myself. Still playing lots on cemu though. The backlog just keeps growing. 😄
