All the VP stuff I have came from either AJ's or from the Usenet (alt.binaries.emulators.pinball).
Never had a problem with AJ's site but I haven't been there in a while, either. Oh, and AJ's and VPForums.com are essentailly the same place. Both owned and run by AJ and share the same database and files.
For the usenet, you'll find that it's not very active but stuff does appear there sometimes. You just have to watch for it.
Good luck

edit: got the usnet newsgroup address wrong
