A few years ago, an Australian Sonic fan named Christian Whitehead created a proof of concept of a reprogrammed version of Sonic CD for iOS. The demo video quickly vanished, but not due to a copyright claim from SEGA. Instead, the house that Sonic built actually displayed unprecedented coolness by hiring Christian to fully develop Sonic CD for multiple devices, including the Xbox 360 and Windows Phone. After interviewing SEGA about the game, we came away excited.
The WP7 version appeared 11 months later than the XBLA one, prompting many to wonder whether it had been discreetly canceled. Luckily, the Aussie dev continued plugging away on the XNA port of his Retro Engine, and now Windows Phone gamers can enjoy a virtually perfect port of Sonic CD.
