Dear White Elephant,
I agree: the real question really is "Where can you get a copy of the old game Lemmings?" Please, tell us the answer. That game was my first love in life. She never broke my heart. Too bad we somehow got separated over the years.
Old computer game stores are good for this sort of stuff. But this is your lucky day--Lemmings is for sale on amazon.com. Actually, there are three Lemmings games there, but it looks like the top one is the original. Look for Lemmings under "computers" on the Website. It's $19. I'll have to pick that up next paycheck...
