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.
Sonic 1
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 2
It is conjectured that this is the "02" revision of Sonic 2.
