 The game's soundtrack, which features chiptunes rendition of The Beatles songs "A Hard Day's Night", and "Twist and Shout", had permission granted by JASRAC in Japan, with a license displayed on the instruction card and printed circuit board.A revised version of the game, titled "High School Graffiti Mikie", provided less violent action, in which Mikie's physical attack was changed from a head butt to a paralyzing shout, while his "death" animation was changed from rolling around on the floor to sobbing in contrition.The glass jars, which Mikie had to head butt three times to retrieve the heart inside, were replaced with bundles of three hearts, providing the same effect without requiring the player character to head butt glass.
