I apologize I thought I had them listed.
1. If, a VN for the PC98 that has three short scenarios. Music from Keishi Yonao and Yasuo Ito, but they only did the first one of the three.
2. Desperado X, a remake of a mecha side-scrolling shooter ala Defender for the X68000 computer. Music from Naoya Kawahara, and this was left unused.
3 & 4. Megumi Rescue(Arcade), so I have to say the Arcade version because it was thought to be lost until it was recovered a few years ago. This was technically Aicom's first game, but they retooled it for the Master System since the arcade version had similar hardware. These tracks are from Hirohiko Takayama, but he went uncredited and Kiyoshi Yokoyama also did the music but got credited(probably because he was assigned to the game early then Takayama was put in later)
