Is this WC1? If so, good luck slowing it down significantly at all. There is a program called moslo, which can slow down your computer, but most people can't get it to work successfully with WC1. I tried it myself, but even at the slowest setting, the game was still too fast. Still, someone else more knowledgeable than me (i.e. everyone else on this site, pretty much) may be able to help you. You could try moslo, though, and I think you can get it on this site somewhere.
