I had a cracked version of Turbo Esprit game on Amstrad CPC. There was one utility pole in the game in one of the maps. You reached to it by turning left at the start and then right, and it was second pole on the right, or something like that. If you hit that pole using "street turn" action, you'd instantly get teleported to another street with hundreds of pedestrians, climbing up to the sky. I thought I'd found heaven, but now thinking about it, the glitch might be caused because of the crack and repackaging. I loved discovering such an obscure behavior in a game though. I couldn't reproduce it on an emulator again.
