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.
