# SPEED RE: reconstructing the Need for Speed Underground 2 engine

> SPEED RE reconstructs routines from the SPEED engine using Need for Speed Underground 2 PC v1.2 as its reference. It documents recovered physics, collision, camera and HUD code, compares some functions byte-for-byte or through bounded execution, and runs an incomplete Linux driving demo on a user's installation.

## Requirements & limits

- **Prerequisites:** A lawfully obtained Need for Speed Underground 2 PC v1.2 installation, including the supported speed2.exe, is required.
- **Prerequisites:** The native demo requires a multilib C++ compiler and i386 SDL2/OpenGL libraries and headers.
- **Limits:** The reconstruction and demo remain incomplete; matching and behavioral results cover selected routines.
- **License:** The MIT grant in LICENSE covers original contributions only and excludes recovered game code.
