Apple's finicky about emulators in the App Store, but most of the candidates have been unofficial, and dubiously legal. Sega's Ultimate Genesis, though, is official, and looks like a full virtual console for your iPhone.
Sega's released a pile of classic games in the App Store, all of which were technically emulated; the apps were emulators and ROMs, all packaged into one. (This made the adaptions faithful, if a little slow on non-3GS hardware.) Now, with the App Store's in-app purchasing system, they can do it right: the free app, which should show up sometime
today in the beginning of February, comes with just one game—Space Harrier II—but you can buy as many as you want from within Ultimate Genesis. Here's the current lineup:
• Sonic the Hedgehog: $5.99
• Golden Axe: $4.99
• Ecco the Dolphin: $2.99
• Shining Force: $2.99
Some of these games are already listed as standalones, so in an abstract way, Ultimate Genesis is really just a new way to package old apps, and a focused sales channel for new ones. But that's exactly what a Virtual Console-style emulator is! And why this is a fantastic idea. [Sega]
