Put down the Visine, bunky, your eyes are not deceiving you — that IS SNES Mario Kart running on an iPad, courtesy of emulator guru ZodTTD. So with various iPad jailbreaks already popping up like so many (Mario World!) mushrooms, it may be just a matter of time before you can drop the game ROM and Zod's snes4iphone emulator onto your pwned 'Pad and speed away.
BUT WAIT! There's more! Zod's claiming he created a "legal" (i.e. no-jailbreak-required) version of the emulator, even going so far as to submit it to the App Store:
The build of snes4iphone running on my iPad as seen in the video was
actually based on an AppStore app I submitted called "snesty". Apple
quickly rejected it right after pulling the NES emulator. I combined
snesty with some snes4iphone features such as using the private API
called CoreSurface. I used Apple developer tools and self signed it.
He also promises a version of the emulator that'll support the iPad's 1024 x 768 native resolution and even touchscreen controls.
At the risk of stating the obvious: KNEEL BEFORE ZOD!
