Weird Sonic 2 Cartridge

[old_skoolin_jim]

I have a copy of this as well, same label and sticker. I also have that bizzare carboard box sonic 2 that nobody has been able to identify either...

I'm 99% certain the Sonic 2 with the cardboard box was part of the flood of re-issues at the end of the Genesis' life (circa 1996-97). I also had a copy of Battletoads with a cardboard box (which I sold promptly after I beat it... man that end was a slap in the face, but I digress...) as well as Road Rash 2 that came in a cardboard box and had a standard, non-EA cartridge.
Just my $.02
