Those are all fine suggestions and all, but if you have a modern computer, it is much easier (and much more accurate) to just download the DOSBox computer emulator. DOSBox emulates a mid-range 486 when run at high cycles on a decent modern computer, and will play most older dos games at a decent clip. You can get the D-Fend user frontend here , and create custom configurations for each game you want to play, then simply double click to play them.
