在PRG ROM中有来自Deja Vu的原型版本的图形隐藏?.
The options and Kemco logo were moved up in the USA version to accomodate for more copyright text. The text font has also been changed.
- Rather than start you off when you select START at the title screen, the Japanese version asks for your name and blood type. Depending on selected blood type you'll get the different parameters to your character. The available blood types are RH+, A, B, O, and AB. There is a cheat in the Japanese version, while selecting the blood type, press Up + A + B on Controller 2 and RH will change to RH-, now the whole set of blood types will change and its parameters are higher than RH+.
- Clark Kent/Superman was given a more "chibi" look in the Japanese version.
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.
