James_S_Pratt: This troper is the creator of two GameGenie codes. One was an infinite lives code for the NES version of ''DoubleDragon'', the other was the code which turned Mario (in SuperMarioBros3) into an indistinguishable purple thing who, when you pressed the jump button, actually ''swam through air.'' Sadly I've lost both these codes, but I would be surprised if somebody else didn't discover them.

This troper used to swear by GameGenie and even got into the whole code-creation thing, swapping homemade codes with people online and even getting her ''mother'' in on things. (She created a code for Tetris that let you complete a B game, level 9 height 5 in ''one line''.)
