This project is a modding toolkit for the 2005 PC game Need for Speed: Most Wanted, built specifically for the retail version 1.3 of the game. It gives modders two things at once: a library for reading and writing the game's own file formats, and a set of tools for writing live plugins and trainers, which are small programs that change how the running game behaves. The author's main selling point is verification. Instead of guessing at memory addresses and file layouts the way older tools have done, every address and data field in this kit is traced back to a byte level reverse engineering data set. The README compares itself directly to an older, more established modding SDK for the same game series, arguing that while that older tool covers more games, this one focuses on a single game and backs every claim about the game's internals with proof rather than hand written guesswork. The toolkit is split into two parts. One part works offline and can read the game's compressed files, its texture packs, its 3D models, and its world data, including where objects are placed, where traffic drives, and where the ground collision is. The other part only works while the actual game is running on Windows, and lets a mod read or change values like a car's top speed in real time, using code the author says is regenerated automatically from verified research data rather than edited by hand. The project offers three levels of use, from simple one line changes for beginners, to more explicit control for people who want to name every step themselves, to raw access for advanced users who want to call the game's internal functions directly. It is written in C++20, has no required dependencies beyond a C++ compiler for the offline library, and includes documentation files describing its full set of functions. The README does not state a license for this project.
