i was reading the registers and assembly for the 68k and z80 for misc games because i was bored, and i came across sonic 1.
i disabled the z80, and usually the sound either starts sounding like a 5 year old got ahold of a cat, or it slows down so much that you can hear the individual notes. this wasnt the case for sonic 1, for some odd reason, i guess they wrote the sound driver to run on the 68000, because when i turned the z80 off the music kept playing (all except the DAC)
maybe sonic team didnt know how to code for the z80 back then
either that or they were retarded, who wants to run a sound driver on the same cpu that the game uses to run? if the game was any more complex than it was, it would have had horrid slowdowns

lots of older video game consoles didn't have two processors - one dedicated to the game, and another for sound. using a sound driver on the same cpu as the game doesn't create a lot of slowdown either
