Sorry, I was a bit unclear.
I mean your actual computer's locale is set to Japanese for non unicode programs, right? Are you on Windows 10 or 11?
As for obscenely long filepath, I don't think even the embedded files should be over that, so you should be safe. It's just that from what I have heard, either WIndows or some applications won't be able to find what they're looking for if a path is too long.
It's okay if you downloaded the custom fix version. In the sound category, they're both missing files...though it doesn't look like they should be missing a sound effect in Mamo's scene.
Sorry for all the questions, it's just the fun of troubleshooting, I suppose.
