How to use this famous PCM8 driver?

[Cris1998XX]

So, I know the question might sound kinda weird but I've been looking throught the internet for days at this point. I've heard there is a way to add more PCM sound channels to the X68000, both with software and a hardware card. The PCM8 driver is supposed to be compatible with games like Space Harrier, Street Fighter 2/Super Street Fighter 2 and the Fatal Fury trilogy, but I just don't understand how this stuff works. Do I need to edit the system disk or something? I'm playing via XM6 TypeG if that helps
