UCC.cpp

/*
*	This is a custom UCC.exe for Star Wars Republic Commando since the game shipped without one.
*	Everything compiles fine with Visual Studio .NET 2003 which is being used to achieve maximum compatibility
*	since it was also used to compile RC
*	The following settings are required in order to compile everything without errors:
*		- Character Set = Not Set	//Important as RC does not use unicode
*		- Struct Member Alignment = 4 Bytes	//Probably not necessary, but just in case...
*		- Calling Convention = __fastcall	//RC uses __fastcall as default calling convention
