A few months ago, Apple has released an application called GBA4iOS, this application allows you to install an emulator for Nintendo games to completely run on iPhone even without Jailbreak. Today the project has closed its doors due to a warning sent directly from Nintendo. Let's read more about the topic after the jump.
It was not hard to imagine that the emulator would have a short life, The same fate has meet many other apps in the past. Nintendo does not want to be exposed to their games on other platforms, especially via emulators.
The application will continue to run on all iPhones on which it was previously installed, but it can't be downloaded no longer on the new devices. The NDS4iOS is a same emulator which brings the Nintendo DS emulator on the iPhone.
