Well I started playing with the config file, /home/nemo/.config/mupen64plus/mupen64plus.cfg Increased resolution: [Video-General] # Use fullscreen mode if True, or windowed mode if False Fullscreen = True # Width of output window or fullscreen width ScreenWidth = 1080 # Height of output window or fullscreen height ScreenHeight = 1920 I still haven't figured out how to change resolution to landscape or enable control. There is a lot more settings in the configuration file, if you want to play with it.
