I’ve been messing around with editing map sprites, but I can’t find out how to edit the walking sounds. There also doesn’t seem to be a lot of material on how to go about finding and editing the walking sounds either so I’m at a bit of a loss. Any help would be appreciated.
Lisandra_Brave made a Nightmare module for it.

That module was for FE7 and I don’t know how to edit it to be usable in FE8, nor can I find any documentation or tutorials that will tell me how.
