Those are probably line-out from the sound test menu. We want the giant archive (or however they stored the sounds) from the disc itself. Unfortunately, I do not know how to dump Wii U ISOs, nor do I know where to find them.
I can at least get all the SFX extracted with proper names this weekend. I've been wanting to fix my nus3bank extractor. I'm only gonna do the USA version though.
Oh, the sounds are also in a nus3bank? Interesting. If you're only going to do the USA version, can you post your extractor so other people can extract the other versions?
OK but am I the only one that actually downloaded the files from sounds-reasource? If u download them, especially the enemy sounds... I think you'll see that they most likely are the legit files.
