Your first sentence pretty much answers your own question. The xbox mold is not compatible with the ds4 internals.

The amount of work that would be required to do what you are suggesting would basically mean building a controller from scratch. I am not an engineer, if you are then you'll need to explain how this would work. What you are suggesting is nowhere close to being as simple as you are making it sound. The internals of a ds4 are completely different from the internals of an xb1. Whatever controller you manage to create from that would be a frankensteins monster that is barely functional. I honestly don't understand why you would even think that this would be a feasible option. If you really know a way to make this work then I'm all ears. You'll need to be a little bit more specific than "put ds4 board in xbox mold."

Do you have evidence of this?

Google articles about using PS3 controllers on PS4. PS4's had an update about a month ago which allows you to use PC controllers as well as PS3 controllers on the PS4.

So PS4 can use every controller PS3 could now.

Hmm... I had an adapter that allowed me to use a wired xbox controller on ps3. If your right then maybe that will work. Thanks for actually presenting an option that makes some sense.

Well yeah but software authentication is tied to the hardware not the software itself. Thats like saying "okay the software is authenticated: success" and then your controller disintegrates. Sure your software is authenticated but if you dont have the hardware its pointless. The thread should be titled "So it turns out the PS4 doesnt allow unlicensed controller" because thats all it is. Software authentication tied to hardware is synonymous with the hardware not the software its running. They arent mutually exclusive. The process of authentication requires software because it in fact is a code but the hardware is what is being authenticated using the code, not the software required to authenticate.

If you truly don't see the underlying subtle point of this thread you're purposefully being obtuse. You construct many complete sentences and argue your point well even if it is not agreed upon by 95% of rational members of this community so I know you understand how to read between the lines of "so it turns out the ps4 does have software authentication"

So please stop ruining the reputation of one of my favorite bands, go buy a Xbox One and stop with this ridiculous ranting about using unlicensed peripherals on the PS4.
