Sonic Mega Collection GameCube

Sonic Mega Collection is a single-disc compilation featuring all seven Sonic-related games released on the 16-bit Genesis console during the years 1991 to 1996. None of the games have been enhanced specifically for the GameCube and are presented in their original, emulated form. Featured titles include Sonic the Hedgehog, Sonic the Hedgehog 2, Sonic the Hedgehog 3, Sonic Knuckles, Sonic 3D Blast, Dr. Robotnik's Mean Bean Machine, and Sonic Spinball.

Multiple versions of Sonic the Hedgehog can be found on the disc, including the original American release, the later Japanese release with slight cosmetic enhancements, and an even later Japanese release that corrects a few minor glitches. As a special bonus, players can access a number of extras, including five movies, a complete series of comic book covers, and various character illustrations. The original Genesis manuals are also included on the disc for players who wish to see them in their unadulterated form.

By satisfying certain in-game conditions, players can unlock five bonuses from the menu screen. These bonuses include the ability to play as Knuckles in Sonic the Hedgehog 2, play both Sonic the Hedgehog 3 and Sonic Knuckles as one fully connected world, and experience an extra series of Sonic levels. Two complete games are also part of the mix, including 1991's Flicky and 1995's Ristar. In addition, the controller functions for each game can be customized and saved within the options screen. ~ Scott Alan Marriott, All Game Guide
