Installation Tutorial:

Step 1: Go into your game installation folder (it should be something like this: Steam\steamapps\common\CHAOS;HEAD NOAH).
Step 2: Go into "Data" folder and make a backup of file named "system.cpk" in case something goes wrong.
Step 3: Replace the original system.cpk with DS4 or Pro Controller system.cpk.
Step 4: Boot the game up and it should work.

This mod is also compatible with the Committee of Zero's CHAOS;HEAD NOAH Overhaul Patch and Japanese build of the game.

I've no idea if it works with GOG version as I haven't tested that one. If someone can test it, feel free to report in the comments if it works.
