Best described as Photoshop meets Mario and sidekicks, Mario no Photopi is one of the more obscure Mario titles, perhaps for obvious reasons. This failed attempt to expand on the Super Nintendo's Mario Paint, a game that came with a mouse and allowed players to make images and music, never saw daylight outside of Japan, becoming something of a holy grail among collectors.

But thanks to a tireless Nintendo 64 ROM hacker by the name of Skelux, all those long, somber years of Mario-less photoshopping are a thing of the past. Released last week, the "Cardless Hack" circumvents the game's funky setup, which prevented it from being played in emulators until now.
