This is an a6 client.exe that I tried editing to make it read the new 3d mesh. I was not able to test it as I don't have a working server.exe, nevertheless the exe launch without any issue. I am sharing it perhaps someone might be able to test it and share their feedback if it works or not.
feel free to test it out and see if it works in your files. for any additional question feel free to DM me here is my discord: madclawn6521
note: version.ini is packed inside exe so use the version.ini that's on this file.
