Those of you whom have played around with Installer.app have no doubt seen the ultra-cool NES emulator that the third-party application package provides. Now, jailbroken iPhones now have a Gameboy app which allows you to play emulated Gameboy games on the device. The interface looks to be just as cool as the NES interface, though we hear that the sound of the games still is in need of some tweaking. That’s to be expected from an emulated third-party application on a hacked device.
