If you want to run emulators on your iPhone (or iPad), you’ve basically got two options: Use this crazy workaround which involves rolling the date of your device back to 2012 and installing old, previously signed emulators. Alternatively, you can just bite the bullet and jailbreak and install any number of emulators that people are actively developing on Cydia. Well, as of this weekend there’s a third option. Like the previous two solutions, the third isn’t very ideal either, but if you want to play NES games on your iPhone, it’s worth checking out. Thanks to a new open source web app webNES, you can now play NES games on iOS devices without jailbreaking or installing anything. It runs a little slow, even on my iPhone 5s, and sound only works through headphones, but the fact remains: It works.
