I am trying to edit the graphics on a game and have a .nsh file where post-process effect data is contained. I cannot seem to find a program to extract/read its contents.

Googling it, I see something about NSIS packages but nothing past that.

Edit: Link added for the file. This is for Naruto Ultimate Ninja Storm 3 Full Burst HD on PC (dx11), and I have also uploaded the corresponding nsh files for ps3, xbox360, ps4, and dx9 (win32)
