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.
