My ported version is compatible with PCSX2 1.4.0 and is built using the latest source code of GSdx (Graphics Renderer) as of the PCSX2 1.4.0 release.
GSdx source code was changed substantially since 2013 when he posted his patch. This required a lot of work involving thousands of lines of code.
I have also added a simple Stereo Mode selector in the Plugin Settings and fixed a bug that crashes PCSX2 when you enter a battle in the game Grandia III.
