Generally speaking i'm not against it. I never heard about PC games using this PSG.
But ao486 core is PC/AT oriented, not XT or PCJr, thus it may conflict by ports with those addons. Port C0 is used for DMA.
Probably it's better to port other PC (PC/XT) core to MiSTer and keep that as XT/PCJr compatible. i486 should be anyway too fast for those games

The conflict on C0 explains why later Tandy machines moved access over to 1E0, which of course breaks software....
I think that overall speaking it is indeed wise not to mix up machine types too much. With IO port C0 there are resource conflicts and when moving things over to another port software won't be able to utilize the PSG without modification. So overall, I guess there's little point overall.
Thanks for your thoughts!
