To a 3-year-old, it's a logical enough assumption: We can play as a girl, Princess Peach, in Super Mario Bros. 2, so we should be able to play as Pauline in Donkey Kong. Most seasoned players know this isn't the case, since Donkey Kong features a static game of boy-saves-girl - until now.

"My 3-year-old daughter and I play a lot of old games," writes one dad on Facebook, as picked up by Reddit. "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."

To put a smile on his daughter's face, this dad hacked the 2010 NES Donkey Kong ROM, using Tile Layer Pro, and swapped out Mario with Pauline. He shows off the end product in the above Donkey Kong: Pauline Edition video, though we don't need visual confirmation that this is the most adorable story we'll write today.
