Gamer dads are the best. Look at the length one dad went to make his daughter happy.
That’s Pauline (the name of the princess before Nintendo changed it to Peach) rescuing Mario in a hacked ROM of Donkey Kong. Mike Mika’s daughter loved Super Mario Bros 2, where one of the playable characters is the princess. It’s a very simple hack or hilariously complicated, no one knows as the details weren’t communicated over Reddit, where the hack was first discovered. Users also noted how this ROM of Donkey Kong is from the 2010 Wii version.
It’s the same game with a character swap to make every Donkey Kong fan happier. As Arstechina reported, Mika could have used Tile Layer Pro, an extremely popular ROM-editing tool. ROM hacking is old news, with an almost infinite number of hacked Nintendo games available. This one just happens to be the simplest, and cutest of the lot.
