Hyper Duel - Sounds just as good as the Saturn version despite the "lowtech" soundhardware
Macross(1) - Great chiptune like music
Fire Barrel - I might be wrong about this but i have not found it in M1 ;-)
Lethal Crash Race - well, most tunes are technoshit but three non-technotracks are some of the best tunes i ever heard.
Skull Fang - even if the compositions are great so are the soundquality shit in the arcade version... So much for Data East's 32-bit MLC-system... they don't even mention the soundcapabilities of it if you look here
