"Dual Monitor" support (VGA/Hercules)?

I have several old DOS programs that use two graphics adapters at once. A VGA card is always used as the "primary" adapter and the Hercules cards as the "secondary". For instance, several old C compilers had the option of showing debug information on the second (Hercules) adapter.

How all these program work is simply by writing directly to memory >0xB000:0000.

Will this be supported in a future version? So for instance that the Hercules output is shown in a second window?

Too bad. There's a large amount of old business software for DOS out there that use this "dual" monitor setup. Like I said, many old C Developer Kits (like Watcom and Microsoft SDK) for instance, as well as some CAD programs.

I've actually heard that some DOS games (such as MechWarrior 2 and Rise of the Triad) actually support using dual monitors to display debug information while you play. I guess this would be a useful feature to put into a patch, just for people to try out.
