Emulate old PC? [closed]

Answer 1

I used a program called CPU Killer to play commandos behind enemy lines on my modern pc. The speed of that game is proportional to the speed of your computer. It's designed for 200mhz so running it on 3GHz without cpu-killer was impossible. :D

Answer 2

there are CPU throttling utilities that slow the cpu down, not entirely sure how much they'd help. Heres a link to one I just found with a quick google.
