Emulator is slow, how can I speed it up?
By default, most of the settings Yabause uses -should- be fastest available. That being said, there's a few things you can try and see if it improves anything. Make sure "Auto frameskipping" is enabled. Also, you can try switching the video cores between OpenGL rendering and Software rendering. Also make sure there's no other programs running that could potentially interfere with Yabause. Such programs include other games, anti-virus scanners, or video players.
