    "Description": "Hello.\n \nThere is a python script which allows extract information from some particular game files. Those files have blocks of data encoded with some algorithm and then compressed with zip.\n \nNow I'm trying to translate that script into C# and I have problem with zlib decompression part. If you see the script on line 237 you'll see that the block size for extraction is negative. According to Python documentation it's undocumented mode that force the zlib decompressor to skip standard gzip header verification on read.\n \nhttp://docs.python.org/library/zlib.html#zlib.decompress\n \nSo my question is - how can I do the same with DotNetZip library? Cause when I try to decompress exactly the same data I got \"Bad state (unknown compression method (0xDE))\" exception (and I verified that I got identical data right before decompression step in both my version and python script version).",
