I just compared the ID values of the old and new controller and they are different. The new PS4 controller has a ProductID of: 0x09cc. The VendorID is still the same. I guess it will have to be added to the source code.
Calling
@FIX94 to add this controller to the source.
EDIT: The new PS4 controller was added to the code. Make sure you have the latest version of Nintendont 4.436.
I should also add that the PS Controller code was modified to fit the GameCube controller so the buttons were remapped so going back to the old controller isn't going to help.
My guess is that the ProductID in the ini file you were using was for the v1 PS4 controller and not the v2. Change the ProductID to 09CC and it should then work.
