Sonic the Hedgehog 2 was released on November 24, 1992 in North America. A reprint later that year was labeled as 'Not for Resale'.
Sonic 2 had a release date in most Western regions which was uncommon at the time. November 24, 1992 was dubbed Sonic 2sday (a pun of the fact that it was a Tuesday), and the game was released throughout North America and the PAL territories. (It was released in Japan three days earlier.) This is referenced in the game by the order in which you need to play the sound effects to activate the debug mode.
