Not wanting his daughter to hit the glass ceiling in gaming so early in life, Mike Mika edited the classic Nintendo game Donkey Kong so it's the princess that rescues Mario (known as Jumpman back then) from the game's namesake villain.
Mika's daughter Ellis is an avid player of retro games, but wanted to play as Princess Pauline in the game as the hero.
"Two days ago she asked me if she could play as the girl and save Mario... I told her we couldn't in that particular Mario game, she seemed really bummed out by that," he writes on a Facebook post.
Using ROM editing tools, Mika switched around the pixel sprites and colour palettes. The gaming isn't perfect he admits, but it's put a smile on his daughter's face.
Mika's project has taken on its own life on the web, fuelled by the cat-worshipping folk over at Reddit. He's since appeared on TV news in the US, as well as several publications around the world.
Apparently this isn't the first time Mika's used gaming to make the fairer sex very happy. According to friends of his over on Reddit, Mika hid his marriage proposal inside the code of a commercially released video game – waiting almost five years to pluck up the courage to show his now wife.
