In 2009, Sonic & Knuckles completed the Xbox Live collection of Mega Drive Sonics, downloadable on the Microsoft Xbox 360 console, now for only 240 MS points (or a free one-level demo).

Interestingly these are the tracks that are suspected to have been created by a certain, uncredited King of Pop (see the Sonic 3 Miscellaneous page), so there may have been legal issues in including these in this version, if indeed there's any truth to such rumours.

Some, however are completely absent and replaced by original compositions, including both acts of Carnival Night Zone, Icecap Zone and Launch Base Zone, plus Sonic 3's Knuckles theme and the credits music. Most of the tunes we all know and love are still present, but rather than being maintained in their original states, they have been recrafted into MIDI or FM formats. Four Sonic games in one, and they're all virtually identical to their original Mega Drive counterparts, except for one thing. Not only that but hidden in the "Game" menu on the menu bar is "Special Stage mode" which is actually the near-endless bonus game obtained from locking Sonic 1 into S&K. This package not only contains the separate versions of Sonic 3 and Sonic & Knuckles, but also the results of combining the two, creating the ultimate game Sonic 3 & Knuckles.
