Me and Nakeee created a null DSP device, supported in both Windows and linux (tested). Framerate boost and less DSound/LibAO errors. Pending work: Clean up UCodes and create something more...null. We could also hack into the HW Audio Interface (would be actual null device). Also screws up a bit of Wind Waker RTC (awesome day/night transition in save selection menu. 80FPS in save selection menu, 120FPS in logos.
