# Drift City Rebuild: a Unity client and server from game analysis

> Drift City Rebuild rebuilds the online racing game as a Unity client that reads data from the user's installed copy, with a new Node.js server for offline or hosted play. Its reverse-engineering notes document REA/Ghidra analysis of DriftCity.exe and record format readers for NayaPack, NIF, DDS and other game data. The author reports roughly 94% code conversion.
