Not just a simple Game Genie cheat, this geeky dad decided to hack the Donkey Kong ROM to allow his 3-year-old daughter to play as Pauline. That's right, Pauline is now tasked with saving Mario at the end of each stage, rather than the other way around. Continue reading for a video and more information.
Here's what the dad has to say: "My three year old daughter and I play a lot of old games together. Her favorite is Donkey Kong. Two days ago, she asked me if she could play as the girl and save Mario. She's played as Peach in Super Mario Bros. 2 and naturally just assumed she could do the same in Donkey Kong. I told her we couldn't in that particular Mario game, she seemed really bummed out by that. So what else am I supposed to do? Now I'm up at midnight hacking the ROM, replacing Mario with Pauline."
