If Gummo is making the ps2 to ps4 convertor for you this is what he is doing.I'm is dumbs
What does this mean lol
He will use Toodle's FGWidget convertor (http://www.godlikecontrols.com/download/converterwelcome2.pdf) as a ps2 Decoder. What this does is basically read the signals sent out from your ps2 pad and converts it into a wired signal for each button and direction. These wired signals will then be connected to the corresponding signal on a common ground ps4 pad. So your converter signal chain will be Your thumb->ps2 pad->FGWidget-> ps4 pad->PS4. So pressing a button on your ps2 pad activates a button on the ps4 pad. Lag will be non existent since ps2 pad inputs are sub 2 ms.
@C-Sword can tell you more about it if you have anymore questions since he had one made for him by Gummo.
