I just started using an 8bitdo controller. It seems to work with all of the game controls. However, I was bummed out when I lost game exit capability. I then tried to access pause menu and no dice. I am running rocketlauncher in the back and that seems to be buggy with LB these days, so I set up retroarch as an emulator for NES straight through LB. Still had the same results with the controllers( although it fixed a fade screen issue that has popped up around 10.3[positive] but I loose my bezels[negative]) I then tried my xbox controllers with the same results in all scenarios. I don't seem to have been able to get the beta, however, I did get an update tonight to 10.4. Same thing. I am windows 10. I tried deleting the xml to no avail.
