The Japanese version of the game was renamed "The Super Shinobi". Putting a US copy of the game into a Japanese console will still show the title as The Super Shinobi. Likewise, playing a Japanese copy of the game on a American or European machine will still show the title as Revenge of Shinobi.

In the original release, Batman and Spiderman appear as bosses. Batman was later replaced by a different enemy, while SEGA added a copyright disclaimer for Marvel Comics, who allowed Spiderman to stay in the game.
