ROM Hack Question Regarding DQ11 S pak files

[Axodique]

I wanted to make a simple mod for DQ11S that just changed a single music, but I saw that there wasn't the music in the romfs. So I guessed the soundtrack was in the .pak files so maybe if I extracted, changed the music, repacked, then did the usual thing for layeredfs, it would work but the music isn't in pakchunk1-Switch.pak and pakchunk0-Switch.pak doesn't want to extract with Unrealpaktool.

Does anyone know how I could make my mod?

Nvm, dumped again and pakchunk0-Switch.pak is extractable this time. bruh.

If you get it to work please share it. I already try to change the music but the files are in the unreal file format.

I'm having trouble repacking though, any ideas?
