Author: Leon
Used Tools: MS Visual Studio 2003
Description: A self written UCC for Republic Commando, still in development. Used for executing Unreal Commandlets.
Github: here
Latest Build: here
UCC.cpp
/*
* This code compiles to a dll. In order to use it, SWRepublicCommando.exe needs to be modified so
* that it calls this dll's 'uccInit' instead of 'appInit' from Core.dll
* Also it's subsystem should be changed from window to console
* Everything compiles fine with Visual Studio .NET 2003 for maximum compatibility since it was
* also used to compile Republic Commando
* The following settings are needed to compile everything without errors:
* - Character Set = Not Set
* - Struct Member Alignment = 4 Bytes
* - Calling Convention = __fastcall
