The original version was released for the Genesis in October 1994. A version for the Super NES was released shortly after the original and is largely the same as the Genesis version. The Super NES version has altered graphics, with alternate backgrounds and special effects, but lacked some sound effects and one of the levels from the Genesis version (titled "Intestinal Distress"). The stated reason for the Genesis version having the extra level was that the "Genesis version was more easily compressed and had the room for the bonus level". Subsequently, Nick Bruty has stated in an interview that Sega asked Shiny Entertainment to add a level exclusively to the Sega version in exchange for reduced cartridge cost. Nick states that they designed the level overnight, and completed coding and testing the level in a single day–the day the game was sent to be printed to the consoles. The game was released in Japan physically only on Super Famicom on June 23, 1995, published by Takara, while the Japanese Mega Drive version was available exclusively via the Sega Channel service on December 1, 1995.
