NOTE: This copy of C9BBS.EXE works ONLY on Wildcat! BBS software. I have tested this on WildCat! v3.55 and have found it to work with no problems that I could detect. Installing the C9BBS.EXE program. Is easy... :) just copy the 'C9BBS.EXE' file into the subdirectory, (Probably c:\c900\) that contains your C900 Service software. That's it folks.. The C9DOOR.EXE program will automatically recognize the executable, and your off to many happy customers....
