I recorded VGM using blastem, I don't know if this is normal or not. Because it seems so confusing. I won't be able to find a starting point for VGM.

That's normal, however you can strip out the DAC/FM5 channel via vgm_ptch to make the disassembly a bit eligible. Just make sure to keep the original log on you since you can't get that data back after stripping it.

The game's sound driver probably does a constant PCM stream, which is the reason for the regular DAC commands.

vgm2txt will not filter anything. Everything works as intended.
