SNES (HD) is my iPad port of the popular Super Nintendo emulator Snes9x. Though based on ZodTTD’s iPhone port snes4iphone, Yusef Napora has rewritten most of the iPhone specific code to work within the iPad environment.
You’ll need a jailbroken iPad and iPhone to play, which I don’t have, so I can only imagine how great it is to have an SNES have the size of all those textbooks I never read.
You can get more information, download the source code and donate to the programmer over here at his webpage.
