The date stamp on these files from my computer is between 1999 and 2001. These are the files I used with the CD game install back then. Copied from my computer here. A lot of the files have readme files with info.
I don't remember where a lot of them go or how to set them up. I would have to figure that out again it's been so long lol.
But, the Blood Wiki
seems to have a good amount of information about them.
Also it looks like doing a google search on some of these reveals that File Planet has an archive of some of the Shogo files with some info.
