For a short time in December 2009, it was every iPhone gamer’s dream come true: a full-fledged Nintendo emulator in the App Store. Nescaline cost $7 and let users load classic NES ROMs through the iTunes file sharing utility. (Image from TouchArcade)
Violation: Apple said Nescaline was removed for being “an emulator,” according to developer Jonathan Zdziarski, but other emulators such as C64 have been allowed. Potential copyright violations were probably to blame.
Jailbreak Alternative: A version of the app, simple called NES, is available through Cydia.
