A question about XENA/XMOS

- you have a supported soundboard by DOS (you wouldn't want to run your game without soundblaster sound, right ?)

I don't believe that modern graphics cards are backward compatible with all the old vga modes either.

Doesn't the emulators use overlay to scale up those old modes?

This was in relation to running old software on a modern pc without using an emulator.
 
It's not just a case of scaling the graphics, older modes were planar and had much different layouts in memory.
 
I believe there are some old PC demos with effects that can't currently be duplicated on emulators.
