Sega's title will emulate cartridge lock-on feature on Japanese Virtual Console.
Sega of Japan has recently announced that Sonic & Knuckles will be released on Virtual Console in Japan. Like its counterpart on Xbox Live Arcade, this downloadable version will replicate every feature of the original title, including its revolutionary lock-on technology.
When you boot up Sonic & Knuckles, if you have any of the three Sega Genesis Sonic games on your Wii you will be able to "lock-on" the game through a menu. Once you select your game you will be able to access all the bonus content, including extra bonus stages in Sonic 1, the ability to use Knuckles in Sonic 2, and access to an additional stage in Sonic 3.
Sonic & Knuckles will be available on October 27 in Japan for 600 Wii Points, the standard price of a Sega Genesis title in Japan.
