Example way of hooking functions in early version of MapleStory. Only tested with veresion v28.

Make sure visual studio is installed and edit the VSTOOLS variable in build.bat to point to your installed version of vcvars32.bat. Make sure you point to the 32-bit version.

Download and install the DirectX SDK 2006 and make sure the INCLUDE_DIR and LIB_DIR variables in build.bat are pointing to your install.

Download the Microsoft Detours repo and compile the x86 lib and copy the compiled lib and header file into this directory.

Running build.bat should compile the DLL.

Once DLL has been compiled use a tool such as CFF explorer to add the DLL to the ijl15.dll import table.

Make sure the ini file suplied is placed in the same folder as your MapleStory exe.
