This track definitely took a hot minute to complete. I started it as soon as I finished Route 206, but the difficulty of porting the track made it take far longer than I wanted to. I experimented with duty cycle changing but it didn't sound like Pokemon Red. It sounded good, just not like Pokemon Red. The ability to shift the duty is still in the file, if you wanted to do so when importing into your project.
