I looked up the Blood Lines characters, and some of them match up with the MAN.CFG names (not all), but not so much for the file names.
Blood Lines characters are: Alex, Maya, Khafka, Lupo, Walker, Reiko, Bomani, Jon, Angor, Daria, and J.O.E. Some names may be changed due to localization or just changed during development. So you were correct to assume that this may be more than just a bootleg. I mean, it might very well be, but that doesn't make the contents less important.
Hmm... Maybe we can get the Blood Lines files to compare. Unmatching filenames could be typical to standard development.
