If you're talking about the overhead stages, that's not Mode 7. Even the Turbo can do that (albeit on one layer).
As for UN Squadron, I simply cannot stand bad, MIDI-ish fake guitar. It just sounds so bad and the overall sound quality of all the instruments is pretty low. With a better instrument set the music would be good, but wah wah guitar is not even pleasing when it comes from a real guitar much less a cheap synthed one.
Some commenter on Youtube was not happy that I kept mentioning the TurboGrafx.
