Original Demo Recordings

During the 8-bit and 16-bit eras, video game music would be performed differently, before being converted to the appropriate format for the finished product. These demo tracks were recorded by Kazunaka Yamane on the Korg M1, Korg T Series and DW-9000 keyboards in July 1992. The tape was re-discovered twelve years later in 2004, albeit in very poor quality.

	Alternate track for Mission 7-2. Unreleased until 2004. It was rejected for being "too similar" to another tune. The tune in question was never specified, but it might have been the intended Mission 2 theme.
