Moraff's Escapade for early Windows, or more specifically, the glitch levels in it.
If you spam the "next level" cheat button (which if I remember correctly is F8) enough times you'll go past the levels that were intentionally designed and start exploring the game's RAM.
Interesting!! I'll have to check that one out. I was a big fan of Moraff's World and i played a lot of Steve Moraff's other shareware games back in the day. Never heard of that one though!
