Finally got a video demoing some controllers with this for use with the ps4.
Here is the description I intended to write down.
Why a convertor and not a dual mod?
It comes down to preference and price. I like to play multiple fighting games, but use different controller types for each one. For example, for capcom fighters I prefer a stick, for NRS fighters I prefer a hitbox and when gaming in the early hours of the morning, my wife and son prefer I use a pad. Quad modding all these controllers to work with current and next gen systems would cost too much money. A convertor just makes more sense in this instance.
What does this convertor do and how is it assembled?
This convertor is composed of 2 components:
Undamnded USB Decoder: This takes inputs from your 360 or PS3 USB controller and turns that into wire signals that you can use to control anything. Info thread on SRK (Undamned's USB Decoders (USB to JAMMA, etc.)! ) and where to purchase (http://www.paradisearcadeshop.com/undamned-usb-decoder/1491-undamned-usb-decoder.html).
Common Ground Donor PS4 or Xbox One PCB: This is the pcb that will communicate with your next gen system. For PS4 pad I recommend the Hori Fight commander 4 (http://www.play-asia.com/fighting-commander-4-paOS-13-49-en-70-7sn9.html) and for Xbox One I recommend the Hori xbox one horipad pad (http://www.amazon.com/HORI-HORIPAD-...ywords=hori horipad xbox one wired controller ). Information on how to hack these pads can be found on SRK (PS4: Third party PS4 padhack options for Xbox one: http://forums.shoryuken.com/discuss...f-third-party-xbox-one-padhack-options#latest ). Thank you @Gummowned.
We can take the directional and action output signals we get from the undamned usb decoder and connect them to the corresponding signals in our doner pcb pad to make a convertor that takes as its input 360 or ps3 signals and outputs an xbox one or ps4 signal. This is a convertor.
What about input lag?
Your lag, if any can come from 3 sources in the chain:
360/ps3 input controller -> Undamnded USB Decoder -> Donor PCB
There are about 16 ms in one frame. Typical input controllers can range from 1ms up to and beyond 14ms. The Undamnded USB decoder has been tested to show that it only introduces 1ms of latency into the chain. Since the undamned usb decoder and donor pcb will be constant in your chain and can be expected to be about 3 to 6 ms in latency, the biggest contributer to lag will be your input device. You would want to use something that keeps you within that frame window. You can use the data on this page (http://www.teyah.net/sticklag/results.html ) to help you figure this out. To be honest, we are talking about ms differences here and in most cases below 1 frame. Many of you will not notice the difference.
Why this convertor over other commercially available convertors?
There are severl advantages to this convertor over commercially available ones.
Since you are using officially licensed controllers as your donor pcb, you do not have to worry about your convertor being patched out in a firmwared update.
No lockout by the ps4. All commercially available convertors on the market have to deal with being booted off by the ps4 after 8 minutes. This is due to the convertor not being able to authenticate itself via bluetooth to the ps4. Since you are using an officially licensed controller pcb to directly communicate with the ps4, you will not have this problem.
Tournament legality. Undamnded USB decoder has been used at EVO and TFC. It was used to run SF ST on superguns. Simply put, it has no macros, you are coupling it with a licensend wired controller. It is tournament legal
Currently Supported Input Controllers:
The controllers on this list are controllers that I have either personnally tested or I have seen to work with Undamned USB decoder. If a controller is not on the list, it does not mean it is not supported, it only means that I did not have it on hand to test. Also the undamned usb decoder can have its firmware updated. Future updates might allow for use of controllers that are currently unsupported. You cannot use this as an xbox one to ps4 or vice versa convertor because the undamned usb decoder does not recognized ps4 or xbox one controllers as input devices.
