    Discontinued GTA III, Vice City [UnavailableForLegalReasons - Repository access blocked]

    This project also has an ongoing effort to get Liberty City Stories supported which would bring the game natively to PC for the first time.

  • sm64

    A Super Mario 64 decompilation, brought to you by a bunch of clever folks.

  • Thyme

    An open source re-implementation of Generals : Zero Hour written in C++.

    Get ghidra and follow tutorials for using it to load your target game into it. You then need to map out functions and work out what data structures they used and start writing C/C++ equivalents to what you see. If you want to test them and replace functions one at a time, you can use various techniques to inject your code as a DLL into the original and have it patch the existing functions to call yours. As a shameless plug, check out https://github.com/TheAssemblyArmada/Thyme which is a project I'm involved in doing something similar for C&C Generals Zero Hour to see what we are doing.
