Question about sound and music

[Zambaku]

First I'd like to tell you about my project. I'm replacing all the graphics with those from Zelda and Zelda II (NES), I'm around 40% done. I've replaced just about all enemies except the bosses, and most of the terrain. I'm about to replace the music and sound but I can't find in the scripts where to change what wave it'll use. I've even tried replacing sound effect by re-naming a new sound effect into that of the old one. If anyone have any experience with the sounds and could offer a li'l help I'd be very grateful

I'm pretty sure supersound.dll handles all the game's music and sounds, but I have no idea how to change that file.  Naming the files the same as the ones you want to replace should do the trick as long as they're the same file type (music is .ogg, sounds are .wav, etc).

Hali has it, to change the effect just replace the .wav file with a .wav of the EXACT same name, and the same with .ogg for bgm.
