I feel really stupid but I Can't for the life of me figure out what I'm doing here. I tried following the readme but I have no idea where the .pcm files are supposed to be.
from the readme:
1) Create a folder to hold the game files and place the patched ROM inside
2) Extract the .pcm files from the MSU-1 audio pack into the same folder

where exactly am I meant to extract/get the .pcm files? I figured it was zpw-v1.23.msu but I dunno what Im doing. I thought about just using the alttp .pcm files but I wasnt sure if they were exactly the same. Any help is appreciated.
