Installation

• Download the latest release package from https://github.com/joelek/wc-refurbished/tags and unpack it.
• Copy the executable wcrpatch.exe from the dist folder to the installation folder for WarCraft: Orcs & Humans.
• Run the executable wcrpatch.exe in MS-DOS or DOSBox.
• Launch the game as normal through WAR.EXE.

Development

The original executable is disassembled using IDA - The Interactive Disassembler. The disassembly is not bundled together with this project as it contains the original executable which is copyrighted by Blizzard Entertainment.

New code is written in assembler using the 80386 IA-32 instruction set and converted to binary patches using the Keystone assembler through the compile utility. The wcrpatch utility itself is written in C99 and compiled for the MS-DOS target using the Open Watcom C/C++ compiler.
