You're welcome! It seems that some of neo_viral's uploads have been deleted recently (likely due to inactivity), so the the KFG anthology and KQ8 went MIA along with a few others.
The Manhunter crack password is actually
hunt88_legends. Long story short, there were are versions of these cracks; the original uploader often uploaded different versions with a new password each time; the MH crack present on the site is a reupload of an earlier version, while the password indicated on the download page is that of a newer version. I don't know if there is any difference between the two though. I edited the download page with the correct password - if you encounter any other upload with a password that doesn't match, please do report them, thanks!
I checked the CD image included in neo_viral's now dead upload, it seems that there is one folder per game and per language - you can compare with your version:
(I didn't screenshot all the content, there are many more files)
I could just reupload it as-is, however this is obviously a homemade image - as we can see by the folder timestamps, and by the "Extras" folder which contains some manuals and a copy of Dosbox. The game files in themselves are fine, but the folder dates make me think that the content of the CD has been copied and then rebuilt as a .iso file. If you could send us a 1:1 copy of your original disc, it would be very nice to replace this homemade image with yours - and since the content of the Extras folder, although anachronistic for a 1997 compilation, is still handy to have, we could provide it as a separate download
Basically, all you need to do is to create a copy of your CD using any worthy CD imaging software, pack it, upload it and send us the link. I doubt the QFG anthology comes with a complex copy protection, or any protection at all, so a bin/cue or CloneCD image would suffice. I gathered a few general tips on providing us titles in , let us know if you need any help on the subject, there or in the General Discussion sub forum. Thanks in advance for your contribution
