The Opcodes Restoration Project is a plugin for CLEO v2.0.0.4 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.

Files

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

Use Microsoft Visual Studio to open Opcode\Opcodes.sln. Change the active solution configuration to either III or VC, then build the solution. The plugin will be located in Opcodes\Release\CLEO\CLEO_PLUGINS\.
