This project enables play on existing legacy WoW emulation cores using the modern clients. It serves as a translation layer, converting all network traffic to the appropriate format each side can understand.

There are 4 major components to the application:

• The modern BNetServer to which the client initially logs into.
• The legacy AuthClient which will in turn login to the remote authentication server (realmd).
• The modern WorldServer to which the game client will connect once a realm has been selected.
• The legacy WorldClient which communicates with the remote world server (mangosd).

• Edit the app's config to specify the exact versions of your game client and the remote server, along with the address.
• Go into your game folder, in the Classic or Classic Era subdirectory, and edit WTF/Config.wtf to set the portal to 127.0.0.1.
• Download the static auth seed branch of the Arctium Launcher into the main game folder, and then run it with the --version=ClassicEra (or Classic for TBC) argument.
• Start the proxy app and login through the game with your usual credentials.

example start.bat

"D:/Arctium WoW Launcher.exe" --path="D:/World of Warcraft/_classic_era_" --version=ClassicEra 

• for vmangos, open realmd.conf set StrictVersionCheck=0
• for public serever just change , realmd database can remain 127.0.0.1

Parts of this poject's code are based on CypherCore and BotFarm. I would like to extend my sincere thanks to these projects, as the creation of this app might have never happened without them. And I would also like to expressly thank Modox for all his work on reverse engineering the classic clients and all the help he has personally given me.
