Are there programs that can unpack Wolfenstein *.spk / *.mpk with proper filenames?

I need a file format specification for Wolfenstein (2009) SPKs MPKs. They're not available publicly. UniPyx returns an error:

C:\Users\asd\Desktop\UniPyX-main>python unipyx.py blacksun.mpk blacksun
UniPyX
['Wolfenstein game data', 'Advanced DB Master data (v3.0)']
Traceback (most recent call last):

                  ^^

Why do you use UniPyx instead of the extractor Thief1987 linked to?
