> NFS Online Server reconstructs online services for Need for Speed: Underground 2, Most Wanted (2005) and Carbon. Python services handle game-specific bootstrap, lobby, race relay and Carbon FESL traffic, while three Zig-built Windows ASI plugins connect the original clients to the replacement services.
