Quoted from Mbecker:
Now that stern is done with dmd, it's just a matter of time before color dmd is caught up with all or almost all titles (are there some that won't be possible?).
I don't think there's been an official word if the large Sega DMDs (Baywatch, Frank, Batman Forever, Maverick) will ever be supported. I'm hoping they come through eventually. If it's possible, I'd color Baywatch myself, my fave game.
