The original mapping is all sorts of scrambled. I've gone through and manually remapped everything that is needed, so all you'll need to do to get your PS4 controller working for Black Flag is to copy and paste this bit into your Assassin4.ini file, found in your computers Documents file, at C:\Users\Username\Documents\Assassin's Creed IV Black Flag. You'll need to replace the Wireless Controller DefaultBindings at the bottom of the ini file with this. Be sure to make a copy of the file before changing it just in case anything goes wrong.


And this should at least remap all of the buttons to be where you would expect them! I hope this helps someone!
