The C64 emulator that was pulled from the App Store by Apple for leaving a BASIC interpreter intact has now returned, though we presume it's minus the Apple-offending code. But while it will no longer run your own code, it will run some old-school C64 games, including eight for free with the app, and more coming with in-app purchases. It's got everything you'd expect from an emulator, including original sound and graphics, an auto-save, and the option to play in fullscreen portrait or landscape.
In fact, the only thing it doesn't have is an interpreter, but of course you know why that is by now: Apple doesn't want anyone running code on their devices that they haven't approved through the App Store. The app sells for $4.99 right now, and they expect to release the in-app purchases sometime this December, with no price announced yet.
