Instead of relying solely on the Famicom's synthesis channels, Hummer Team utilized the DPCM channel to stream short, compressed instrument samples. The engine functions similarly to a tracker or early sampler:
Replicating the exact instrument behavior for accurate 8-bit sound design . hummer team soundfont
To understand the SoundFont, one must understand the hardware constraints and legal gray area. Hummer Team was not licensed by Nintendo. They reverse-engineered the Famicom’s audio hardware, which normally used five channels (2 pulse waves, 1 triangle wave for bass, 1 noise for percussion, and 1 DPCM channel for low-bitrate samples).
