So, after a while of not playing it, I decided to install it again. I installed it and what do I see?
The game is 3 times faster than it should be This has happened with another game before but it autofixed after a while. The thing is, this usually happens when you install older games on newer PCs. Thing is, it's the same PC as before. I've read about this problem and installed a game called "CPUkiller" but it didn't help.
For anything you can install under DOS, you can check out DOSBox: http://www.dosbox.com/
It has some built-in controls to adjust speed, so you can get it running as it should be. It's pretty easy to set up, and you can even get Windows 3.x games running by installing that version of windows from within DOSBox.
