I hada listen at the OGGs anyway. If you think that's SID quality sound, you seriously need to go to your room, lock yourself up for two days and listen to the whole HVSC collection, because that is NOT NEARLY CLOSE to how a SID sounds. That's pure, unadultered, YM sound!
(before a mudslinging begins, let me tell you I like the YM sound, but comparing it to the SID is not a smart thing to do, and IMO, teh SId is the more advanced chip. Otherwise, if the YM was so great, how come the ST users wanted to imitate the SID sounds? Trying to immitate the sound of an ooold 8bit commodore c64 chip in the 90s?
