Two of Nintendo's most beloved games are now one - "Super Mario 64: Ocarina of Time" takes "Super Mario 64" and "The Legend of Zelda: Ocarina of Time" and slams them together into something entirely new. The game, which is downloadable for free and playable on free Nintendo 64 emulation software, is primarily the creation of an intrepid modder named Kaze Emanuar. "Super Mario 64: Ocarina of Time" is not just "Ocarina of Time" with Super Mario in it. Instead of swapping Mario into Link's world, Hyrule is re-created in the world of "Super Mario 64" - enabling Mario's far more flexible set of jumps. Moreover, the many characters of "Ocarina of Time" Have been swapped for their Super Mario equivalents. Rather than Princess Zelda residing at Hyrule Castle, for instance, you'll find Princess Peach. Since "Super Mario 64: Ocarina of Time" is a mod and not an officially licensed game, it's available as a free download - the game is playable on Mac or PC using emulation software.
