The title screen in the North American and Japanese versions are almost completely different, likely due to the game's name originally being Sonic & Tails 2 in Japan. The Japanese version also has an option for "3D Stage" that was removed from other versions.

The box-art for the North American and European versions of the game strangely shows Dr. Robotnik's likeness from Adventures of Sonic the Hedghehog, which isn't seen in game.
