With that patch, mednafen 0.9.46 now works even when a gamepad is plugged in. But I can't get mednafen to recognize the gamepad; it doesn't let me map any of its keys. Also, I can say that mgba (the sdl version) has the same problem as the unpatched mednafen. If a controller is plugged in, it shows only a black screen and has to be killed. Works fine without a controller. Micah
