Thank you for the post.
The first link is a copy of my patch collection (see readme.txt in the directory). The issue with your backup is that all filenames have been changed. The client types have been removed. I would download it again and don't change the names. https://mirror.ashkantra.de/patches/
The issue for this is that as an example 184.108.40.206 is a UOML patch and will crash on GOLD client sins it will try to update none existing files like MAP2.MUL which was never included until 220.127.116.11 for gold clients. They streamlined all clients to the same installation and turned them all to UOSA with the 18.104.22.168 upgrade.
The second link is interesting it is a collection of parts to patched clients, but the issue is that larger files like MAP0.MUL has been removed. The Second Age.zip have signs of gold_win32_4-0-2b been applied so it has been patched to AoS.
The last link is always interesting. it contains clients.exe (which is good to have to be able to compare with full clients to see if they are true or fake patched) from some clients but all other files are missing.
I have all full clients in gold series until 22.214.171.124. But client patches RTP/PAT installations for UOTD, LBR3D, UOKR, UOSE and 555 ( beta ) is missing.
I just have installation media for them. I have bought and made the follow ISOS, some is still missing.
