For reasons I wish to understand, mudlord is packing his releases with his personal packing software, which I have a slightly old source code to. Nothing too overt, just a custom loader and LZMA compression.
I say, wish to understand, because I think the source to this software is available somewhere. I think he uses his packer on his releases because he's proud of it. I know I would be, accomplishing something like that at long last. I even helped him out a bit with getting it working on more software, including my initial attempt at handling DLL imports and exports. I think he uses a stock library for processing those now, though.
He also password protects archives on his site, using a common password you may ask him for, or ask him to post here, because he frequently posts files that get caught as false positives by virus scanners, and those files being Google indexed tends to lead to his entire domain being blacklisted by browser security lists.
I stopped having the virus scanner issue ages ago, because I pay the expensive Code Signing Certificate Tax.
