Yes.

For multiple reasons. As a child, I cheated my way through NES games like Friday the 13th and Lifeforce. As an adult, I beat both games legitimately. I also used a code for Mega Man 2 in which only bosses can hurt Mega Man. Not only was it unnecessary, as the game really isn't that difficult, but it also blocked me from completing the game as the Boobeam Trap does not register as a boss.

I also got a Gameshark for Nintendo 64. This wasn't so much about beating difficult games as it was unlocking inaccessible content. There's an Arwing that you can fight in Ocarina of Time. Big Show's likeness is locked away in the code of WWF No Mercy. And you can hack an unfinished Blargg into Super Mario 64. It lacks eyes, but is otherwise completely functional.
