And what about using a psvita as an extra controller instead? As stated
here:
"Some PS4 fighting games support the use of a Generic USB GamePad with
this59 custom driver."
In the list there's also Mortal Kombat X (that has been recently decrypted), so, how about loading the usb driver that uses Mortal Kombat X before launching ANY PS4 game using a little homebrew?
Two steps are required for sure:
1) remove the line in the driver that doesn't let DS3 to work with this driver because (words taken from Skullgirls Encore article): "Bartholow says any device that identifies itself as a DualShock 3, instead of something more generic, won't work with its driver."
2) load the driver using a homebrew
3) play with any type of joystick you want saying trolololello to sony and their "oooh, you have 5 ps3 joystick and you want to use these on your new ps4? so cute..no way, only ps4 controller on ps4"
That would unlock all non-ps4 controllers..with...profit...or also...savings (because you won't have to buy expensive ps4 joystick to play with your friends)

For "Enso hacked" vitas, that plugin could help to identify the Vita as a generic usb controller:

do I need to say anything else except:
1) eagerly waiting
2) charge your enso-henkaku psvitas
3) take my money?
