here's another one of our favorites that we've done, this one an arrangement of Amber Valley from Final Fantasy Tactics Advance:
Here's one most of you probably recognise; this is J-E-N-O-V-A from Final Fantasy VII. This is also one of the ones we're quite proud of!
This one uses the VRC6 expansion chip. you might know it as the reason Castlevania III's soundtrack sounded so different in Japan (the north american NES doesn't support the sound expansion chips for whatever reason, so the soundtrack was redone)
This one's Palace of Salmon from Ys II: Ancient Ys Vanished: The Final Chapter. The name is *supposed* to be Palace of Solomon but it got mistranslated in a particularly humorous way.
This game did have a Famicom release, but the version of this track from that release is a bit lacking in our opinion. Of course, our version uses the VRC6, which Falcom obviously wouldn't have been able to use; it's a Konami-exclusive chip
(here's the official famicom version of it: https://www.youtube.com/watch?v=Q567c0mEEec )
this is probably if not the one piece we're most proud of, in the top three at least
