Change idstring "MHX XXL V1.0" to idstring "MH-W V1.0"
Or just delete this line.

        self.filepath = str(f.read(48), 'utf-8').strip('\0')

    entries = []
    while(True):
        check = f.read(4)
        if check == b'\x2A'*4:
            break
        f.seek(-4, io.SEEK_CUR)
        entries.append(Entry(f))
    for entry in entries:
        print('Extracting: %s' % entry.filepath)
        f.seek(entry.offset)
        data = f.read(entry.size)
        dirname = os.path.dirname(entry.filepath)
        if not os.path.exists(dirname):
            os.makedirs(dirname)
        r = open(entry.filepath, 'wb')
        r.write(data)
        r.close()
    f.close()
    
extract('moorhuhnwinter.dat')

You can extract the archive with that python script
