The Chaos Engine (released as Soldiers of Fortune in NTSC-U areas) for Sega Mega Drive is a competent port of the Amiga classic. However, the pastel colors of the original were replaced with more saturated colors. Furthermore, the game was only partially optimized for the PAL version. While the gameplay speed is slower, the music speed is correct. Playing the game at 60Hz makes the music play too fast. This patch also fixes this.
