Decompress multiple .szs files (yaz0) at once?

Trying to convert the sequence files from Super Mario Galaxy 2 to midi files, so Is there any simple way to do this? The programs I've tried to do this with are either too complicated for me or they only decompress one at a time (which is annoying since I have like 131 of them).

If the program you're using is CLI then you can use a windows batch script. It works right out of the CMD. The basic syntax would be "for %i in (*.szs) do <your extractor exe> <whatever else arguments that are required> %i". %i in this case is gonna be the input file.
