Pushing Buttons: The emulator app helping gamers replay classics from their youth – for now

A new app has been at the top of the charts on Apple's store for a couple of weeks now: Delta. Its app store page is illustrated with shots of very Nintendo-esque on-screen controls, framing screenshots from Game Boy, Snes and Mega Drive games. The reviews are glowing: "I've been downloading tons of games I played when I was a kid, it's so nostalgic!" "This has saved me so much money." And yet neither Sega nor Nintendo has anything to do with the app, and until recently, software of this type was banned from Apple's platforms. Delta is an emulator: that is, a piece of software that can successfully mimic a games console, and can run code designed for that games console (ie, games).
