The NES reads the notes from the HW bank only ($C000-$FFFF)
The built in PCM for MMC5 reads it from $8000-BFFF. My question is, has anyone tried this, or know anyone with experience in this? Ive tried changing $4010 & $4011 to $5010 & $5011, but nothing happens. Plus, idk where the MMC5 would even load the PCM from whichever bank. Any help would be greatly appreciated. I need to figure this out, cause I need to utilize that feature on the MMC5, because Link's flying sword sfx is suffering horribly due to my needed prg writes in the HW bank. |

The MMC5 pcm channel is pretty undocumented and I thnik one game used it for a sound effect and that's it. There are a couple test nsf files around the net, but not much else, people always just used the internal 7-bit DAC instead. |

I obtained some of the games Disch makes reference to regarding thr mmc5 sound, but its difficilt to navigate through the games, they all come up garbage. I tried looking through some of the code, but I couldnt get it to log, most likely because I couldnt reach or do the acyion required to mske it log. |

I do not know, if this helps you, but I seriously hope it does.
