Alas, it looks like
http://bob2resources.ww2airfronts.org/ has gone offline. This was for several years the last resource providing a web presence for the BoB1 BDG patches, .98 and .99. It was functioning a couple of months ago, but it seems it is gone, now. The patches were about 50 and 60MB respectively, and typically titled "bob_v099.exe" for example, if that helps in a search. I guess someone could put them up on on of those file sharing sites if nothing else avails...
EDIT: Ah, see what magic can occur while I'm running a websearch concurrent with my post...
