This is a chiptune version of "Shades of Green" by NemesisTheory (I got permission to do this). I made this in FamiTracker, so I had to abide by the 4 channel limit... well, I sort of cheated and used the 5th DPCM channel so it's not completely 8-bit. I used the DPCM channel for the basic drumbeat only. The echo effect at the end was made using Audacity. It was really hard to decide which sounds to use and what parts of the melody to emphasize due to the tracker limit.
I did this completely by ear. I used no samples from the actual piece.
Do yourself and NemesisTheory a favor by checking out the original version of "Shades of Green."
