Opcodes Restoration Project

The Opcodes Restoration Project is a plugin for CLEO v2.0.0.5 and above for GTA III and Vice City that aims to restore functionality to many unsupported opcodes. Only US v1.0 has been thoroughly tested for both games. US v1.1 and Steam versions of Vice City are supported but they have not been tested.

Building

You can rebuild the plugin for yourself if you want to. Use git (e.g. through Git Shell) to clone the repository and the submodules.

git clone --recursive https://github.com/cleolibrary/opcodes-restoration-project

Run premake5.bat to generate project files for Microsoft Visual Studio 2015. If you use a different version of Visual Studio, open the file with a text editor and change vs2015 to your preferred version. A folder named build is created with the generated project files. Open build\opcodes-restoration-project.sln, change the active solution configuration to Release, then build III.Opcodes or VC.Opcodes. The plugin will be located in bin\CLEO\CLEO_PLUGINS.
