- 在日本版本中，克拉克·肯特(Clark Kent) /超人(Superman)被赋予了更 "chibi"的形象。
The Japanese version had the Superman Theme as the title music, as well as a longer arrangement when you play as Superman. However, both of these were removed in the USA release, and instead replaced by songs from a previous Kemco game, Indora no Hikari. It is thought Kemco's US division didn't or couldn't get the music rights. Some of the other in-game songs have been slightly altered as well. Some other songs from Indora no Hikari were also thrown in.
The Japanese version contained credits when you beat it. However, these were removed for some reason when the game was released in the USA, even though they are completely in English.
