A Qt/C++ connection patcher for the WoW 5.4.8.18414 client — see
MaNGOSPatcher/README.md for build and usage.
It patches Wow.exe and Wow-64.exe in place (keeping *_backup.exe backups) to
redirect the client from the Battle.net login to the legacy grunt logon used by MaNGOS
realmd, and toggles back to the originals with an Unpatch button. Patch sites are
byte-verified against the exact 5.4.8.18414 build, and writes are crash-safe
(temp-file + rename, never a partial in-place write).
This replaces the earlier C# console patcher. Build it with CMake + Qt 6 (Visual Studio
2026 or 2022 toolset); the MaNGOSPatcher/ folder is self-contained and can be copied
out and built on its own.
