Yus! This song in 8-bit :D I love the Fez Soundtrack, especially this song! This sounds almost exactly like it. It just lacks a bit of that reverb-y effect that's not even possible here. Well done!
I tried using 8 channels to add some more reverb, but the sound quality drops off sharply after 6 channels... I know it's accurate to emulate the channel-switching buzz but I wish there were an option to apply a lowpass filter to the N163! (edit: and this is when I discover that there's an option in famitracker's audio settings for this)
