I remember I once went to great trouble to use a succession of old computers to copy my favorite DOS game off of a 5 1/4" floppy into a 3 1/2" floppy, and then from there onto a network, and then onto my laptop, so I could take it to school with me. And in the end, I learned that the game ran so fast on my laptop that your character would move at light speed and then die as soon as you pressed a button, because my laptop was too fast.

There was nothing wrong with the program, it just didn't expect to still be in use 17 years later.

If you still want to play it, dosbox supports adjusting emulation speed.

I kinda do, actually. maybe I will.

It was this game if you're curious: http://www.dosgamesarchive.com/download/the-black-cauldron/
