Motocross Maniacs 2 is a racing game for the Game Boy Color. The original Motocross Maniacs was a popular arcade and console game. This sequel likely focused on fast-paced, side-scrolling motocross racing with a variety of tracks and obstacles.  The GBC version probably retained the lighthearted and fun style of its predecessor, adapting the game's presentation for the handheld's hardware limitations.  The developer and publisher information may require further research, but it would be a company that had expertise in GBC game development.
