Currently there is a problem with having more than one adaptoid plugged in. We are using a mix of accessing the adaptoid low level and with direct input. This is a problem with adaptoid drivers and promises to be fixed in the next adaptoid driver released. AudioHLE support for commercial games was actually ready since nemu 0.6. Well this is much better in this release and works fairly well for most games.
Some game have annoying pops and clicks though.
The speed limiter tries to make it run just right. I have included some new options in the audio config. I suggest you dont modify this options while running the Rom. Results are unpredictable. Turning it off gives you a small speedboost.
