Publisher: Sega |
Sonic Classics is a compilation of three games stored on a single cartridge: Sonic 1, Sonic 2 and Dr. Robotnik's Mean Bean Machine. Known as Sonic Compilation in Europe, Sonic Classics was not released in Japan. It was included as a pack-in for the Mega Drive in Europe.
The three games appear in exactly the same form as in their original release. The only new content is a game selection menu, controlled by using the left and right directions on the D-pad and new sprite renderings of the box art for each of the three games. The menu was changed in later released versions. Once a game is selected, players are not able to go back to the menu unless the console is reset or turned off and on again.
This game is one of two that, when "locked on" with Sonic & Knuckles, will enable players to play the entire Blue Sphere game, instead of just one level. The other game that enables this is the standalone version of Sonic the Hedgehog.
The background music and chime heard when a game is selected on the game selection menu are from the Dr. Robotnik's Mean Bean Machine game.

Sonic the Hedgehog
Same as the standard JUE release, except for a bug in Scrap Brain Zone involving the cycling palette. The bug is caused by the fact that the pointers for palette data are only two bytes long. In Sonic 1 alone, this isn't a problem because palette data lies within the first 0xFFFF of the ROM. However in Sonic Classics, the data comes after 0x10000, so part of the address is truncated in the pointer, causing incorrect data to be loaded.
Sonic the Hedgehog 2
It is conjectured that this is the "02" revision of Sonic 2.
