Dosbox is a great program. It's worth getting a pc from 2002 to run Duke 3d :p
...again you specified having an old computer to run duke 3d. Not necessary.
You're also implying that an old computer is needed to run dosbox. Not necessary either.
So exactly why are you encouraging people to waste money on old equipment when the software works on new equipment?
Huh? My quip about 2002 is due to the pcs at 2002. You could buy a pc at 2002 (Hell, I had a 1800+ and a 2500+ at that time, both with 512 megs ram), that would run those specs needed.
I think my point was that dosbox doesn't need much at all to run, and is far more helpful then just playing Duke 3d.
