Nifty! You can also throw in the CoCoPSG as well.

It uses a YM2149 SSG which is register-programmable the same as the PSG.

Some info and links to my (as usual) terrible example code:

And ... while you're falling down this rabbit hole:

Check out the Game Master Cart

The SN76489AN DCSG is an easy stretch to support along with the PSG.
