Code (Text): move #$0305,r0;105 set control register Lord Almighty! An interrupt for every three audio samples! And at 22kHz, that's over 7000 interrupts per second. Talk about overhead! I don't know why programmers used interrupt driven audio on the 32X when SEGA went to all the trouble of giving them DMA driven PWM. Just set channel 1 of the DMA in either SH2 and let it rip! If anyone is contemplating 32X homebrew with audio, I released an example of double-buffered DMA driven PWM for the 32X over at SpritesMind. If folks are interested, I could post that here as well.
