How to extract sound files
(AKA give up your soul and free time)
The ways of getting your hands on sound files are plentiful to say the least, and things aren’t made less complicated by different fan projects handling things differently. Sound effects that were in the original game mostly seem to be put in normal folders among the other game files. Sometimes this is true for voices as well; the Higurashi patch that enables voices and PSP sprites for the steam version does this. For Umineko, you have some files named arc[#].nsa. If you have voice files, they are most likely in there. This is a tutorial on how to rip those babies open, though -if the link doesn’t work- the program he recommends can be found here .
Hopefully those are the only tools anyone will need. From here, finding a specific sound file is mostly just educated guessing. Files will usually be ordered chronologically and some times grouped by character as well.
When sharing a file it’s easy enough to just puush and link it like so.
