It's still there. Old NMA files that were in the old "archive" NMA site also need to replace the "www" from the file URL with "archive":I don't know why but the links to the child patch on nma-fallout appear to be dead/missing.
archive.nma-fallout.com/nma-fallout/fo1/patch/F1ChildPatch.zip
I guess I could upload them to the new NMA, but last time I asked about old files, the answer I got was something like "You don't need to bother, if it is still downloadable from the archive site.".
So, instead, I have been slowly uploading files that are not available on the archive site anymore.
