Sega shall soon release a (official) Sega Genesis emulator on the App Store! Yes, I know there is a free Genesis emulator on Cydia for jailbroken iPhones, but, we’ll see if Sega’s emulator beats it. Apparently, the emulator will be free with in-app purchases so you can buy more games. The app will come with one free game, Space Harrier II.
