This is a fan translation of the Japanese version of Dynamite Headdy for the Sega Genesis. MIJET,  presumably a group or individual, created this English patch in 2007. While the original game was not officially released in English, fan translations like this make it accessible to a broader audience. Such translations may or may not be perfect and can sometimes contain errors or issues that wouldn't be present in the officially released version of the game in its native language.
