GCN Ripping and Decoding a Luigi's Mansion ROM

[killerloader]

I'm create a luigi's mansion game, right now im using dolphin to dump textures and record game sounds.
BUT, i cannot find a way to get the separate sound files from the ROM.

I've extracted the ROM, but i cant seem to decode many of the files, the only ones i can seem to decode are the model files, but even when i decode them with the "rarc" tool, i get a few .bin files, and no model files.

I've tried using "yay0dec.exe", "yaz0dec.exe", "rarcdump.exe", and some vgmstream dumper thing, but none of them can decode any of the other files inside the luigi's mansion [PAL] ROM

Help me decode the game files
