I tried using the brsar_unpack00 extracting the IplSound.brsar(from SystemMenu WAD) and I got a real WAV file. But brsar_unpack00 doesn't extract all WAV files in that brsar.
VGMT is different from vgmtoolbox? Use vgmtoolbox with riff/wav plugin extracting only a dummy WAV, and using brsar_unpack00 extracting only a real WAV. They don't extract all sound files in IplSound.brsar.
I'm fairly certain that RWAV is different from WAV. However, since I've never used VGMT, I don't actually know what selections are available. Look around, and see if there's an RWAV selection. If not, hopefully bxaimc can clarify. Or, perhaps you can upload the BRSAR/game/WAD/whatever, and have someone else look at it. Unfortunately, I don't have a lot to offer here. There's my 2 cents. Mouser X over and out.

Trying to extract brsar form Wiiplay, I'm using vgm toolbox and under advance cutter I tried all presets under wii and even riff but I don't get any extracted files all it does is just search for strings.
