-cleaned up and optimized audio streaming code, that made it possible to remove the AIInitDMA patch completely
-removed DVDInquiryAsync patch and replaced it with a proper low level one, this lets mario kart gp2 boot
-optimized triforce EXI interrupt code, helps mario kart gp2 to get a bit more stable, please note that it still freezes pretty often on the camera screen
