In Japan a premium version was released containing a "premium disc" with four movies. Accomplishing certain tasks in the game unlocks certain movies. One of the movies features Hatsumi Morinaga, the artist responsible for singing the theme of Kitty-N's stage. This feature contains shots of the artist singing the song in the studio, an interview with the artist, and a live-action version of the game, with costumed Japanese dancers taking the parts of the various characters. The other three movies contained within the disc were all for other Enix games:
Astronōka,
Star Ocean: The Second Story, and
Hello Charlie (released as
Eggs of Steel in the U.S.). The premium version is otherwise identical to the game-only version. The following changes were made in the English
localization of the game: • Hiro's cigarette smoking was removed. • Hamm's general appearance was changed from a
ganguro into a
Caucasian. • In Hamm's song, "
McDonald's,
Burger King, or any other place" was replaced with "Hamburger lovers, let me hear you say ho". • A line in Strike's song referring to alcohol was removed, leaving an instrumental break following the line "Like
Arnold Schwarzenegger, I'm the only true
Eraser". • During gameplay, Strike drinks from a
hip flask in the Japanese version. This was changed to a can of
soda pop. • The songs "Transform, "Waratte Pon", "Aozora no KNIFE" and "Uwasa no KAPOEIRA" were re-recorded to English for the American and European market. Transform kept its title, and the other three were retitled as "SHORTY and the EZ MOUSE", "Bust a Groove" and "CAPOEIRA". ==Other versions==
