"Having been rejected, accepted and subsequently removed, developer Manomio has finally gotten its iPhone Commodore 64 emulator back on Apple's App Store.
Now, with further revised code, the emulator has reappeared on the App Store. In addition to the revised code, Casualgaming.biz reports that the application has received a boost in performance as well as three new games, International Basketball, International baseball, and International Tennis. These new titles join the other bundled games, Dragons Den, Le Mans, Arctic Shipwreck, Jack Attack and Jupiter Lander."
At $5.99 AU, it's one of the more expensive iPhone apps, but if it's just what you're looking for then it's a bargain. Pity it doesn't come with IK+ otherwise, it would be a no-brainer.
