This is a fan translation patch of Coca-Cola Kid for the Sega Game Gear. The original Japanese version was a puzzle game, likely themed around the Coca-Cola brand. The "[En by Filler v1.0]" indicates this version has been translated into English by a group or individual known as 'Filler' – version 1.0 is the patch version number.  Gameplay would remain identical to the Japanese original, only the on-screen text is changed.
