Superdimension Neptune VS Sega Hard Girls Sound effects?

[duce]

Try using vgmtoolbox:
https://sourceforge.net/projects/vgmtoolbox/

In there is xwb and xsb unpacker. Also, upload some of the files you extracted with unxwb.exe to here so I can take a look.

I must be blind or missing something but I could not find a xwb and xsb unpacker in the vgmtoolbox


Also here's the files I got with unxwb.exe in the out folder
