It's in the (massive) NSF request thread on page 5.

It doesn't use DPCM, but instead it writes raw sample data to the $4011 register with timed code. That's why it was harder to rip, the code in it had to be rewritten.
all voices are raw data to 4011????

On this game, yeah all the voices and that guitar sample are raw samples. The drums in the music are DPCM.

In general, if the game freezes while voice is playing, then it's either raw $4011 writes or a 32 KB bankswitching game or both. If the voice doesn't play in the PocketNES emulator for Game Boy Advance, then it's raw.

Partial list of games for NES that use raw for voice at some point:
  • Action 52 (intro) (DMC played raw for higher frequency)
  • Big Bird's Hide and Speak (proprietary lossless)
  • Blades of Steel (DMC played raw for more capacity)
  • Gauntlet 2 (bytes)
  • Joshua (bytes)
  • SCAT (other)
  • Sesame Street Countdown (same engine as Big Bird)
  • Skate or Die 2 (intro) (4-bit)
  • The Three Stooges (2-bit)
  • Wheel of Fortune series (4-bit or other)
I've written decoders for some games' raw sample formats.
i remember

A music tracker that makes sequence files usable by NES programs. It is available for Microsoft Windows or MS-DOS and comes with NES playback code that can be incorporated into a .nes, .unf, or .nsf file using the free CA65 assembler toolchain.

Though NT2 is no longer maintained by its author, you can still download the final version.
