Fantasia and Fugue in G minor ("The Great"), BWV 542 [8-bit, VRC6, FamiTracker]

I've come to start appreciating fugues when I heard the fugue from this piece by J.S. Bach, which was included in my copy of Anvil Studio. It also just has a great start, you know? Anyway, I thought this piece could not be done justice in 2A03, so that's why I used VRC6.
This might just be one of the best organ pieces ever. Now it's on chiptune!
The fugue is also sometimes called "the Great," to distinguish it from Bach's other "Little" Fugue in G minor.
