Sonic the Hedgehog 2 Debug Mode
Most gamers fantasize about tinkering with the code of their favorite games for the sake of sending things out of whack. Sega was one of first to offer that shot, granting access to change the entire experience of Sonic 2 by letting us add more enemies to stages, speed through walls, and transform into objects. The Debug Mode even stored special items the developers never deleted from the code. You can best believe we had Super Sonic turnt up heavy when enabling the cheat.
