Oh, ****, another one of THEM.
The "dosbox" of Windows is Microsoft's _UTTERLY_BOTCHED_ attempt at creating a DOS emulation.
DosBox (the emulator to which I link in my siggy) is a superb freeware program that emulates actually entire x86 PC, not just its OS. And therefore it is perfect for running old games.
Oh, and by the way, get v061, not v063 - I found out that some old games had graphic issues with the newer DosBox versions.
Actually, get both. That way you have both the new, supposedly better, one and the older, more reliable.
