"Underground Concourse", the song from stage 2 of the NES game Journey to Silius, composed by Naoki Kodaka. This was played from a modded NSF file with the DPCM samples fixed to be the right order. You can get it here: https://mega.nz/file/BYtXTKaZ#xGH80E6-v6sAWwYc9afGJmHPCFMUt6lVT0mJGpBaiVk

This recording was made using a modified virtual NES sound chip, the 2A03. It was emulated from a modified NSFPlay. The source code is available from my GitHub repository: https://github.com/kylxbn/nsfplay

The modifications are as follows:
- Floating point mixing and volume adjustment for all channels
- Linear mixing of all 2A03 channels (to avoid DPCM/Triangle volume loss)
- Triangle wave is generated with a pure (non-quantized) triangle wave
- Triangle wave is volume-compensated with an equal loudness contour (ISO 226:2003)
- Noise subsampling is downsampled with floating point math (not audible, to be honest)
- VRC6 sawtooth wave is generated with a pure (non-quantized) sawtooth wave
- VRC7 mixing is done in floating point to prevent quantization noise
- N106 updates channels simultaneously per sample, instead of a round-robin implementation
- N106 actually mixes channels instead of multiplexing each channel
- maybe some small tweaks I forgot
