Shadow of the Beast - The arrangement is awesome, especially the first forest BGM, I like the use of drums.
Hellfire S - Well, most of the arrangement from T's music were awesome, including this "HellfireS", especially the title, the first stage and the second stage.
Monster Lair - also a very good arrangement, far beyond the arcade FM version.
Super Darius II - I like the Arcade FM version, but the SCD arrangement is better, the recording is also need to be mentioned.
Forgotten Worlds - I like the new arrangements, except the 3rd stage, because the use of the electric guitar for the melody is not so appropriate for the fantastic game. I will give Arcade/Genesis FM version higher score.
Fighting street - Again, the arrangement is far beyond the FM version, the most favorite tune for this game is England stage.
Strider - Actually, I got disappointed with this arrangement, some tunes were missing, and the use of the synthesis instruments were not so good. I prefer the Arcade/Genesis FM version, especially the first stage "RAID", FM version got more Slavonic feeling.
Art of fighting - I have all the arcade card fighting games, but I think the CD version of those fighting games were too crystal clear, the Arcade version has more dirty and bass sound, which is more suitable for the fighting game.
SNATCHER - Although some of the tunes were made of PSG, the CD arrangements were awesome, when I first time heard this RSS recording soundtrack 20 years ago, it's really shock me.
