This buttons are for Aftermarket PC controllers - that are knockoffs of DualShock 3/4,
i recently got a pair of them for my couch co-op pc.
As a pc gamer I`m not used to console button layouts so i made a this remix of DualShock 3 buttons with xbox layout, so me and my wife can stop looking at the controller every time we play something.

I`m thinking to make a full stand + usb hub for receivers and charging so follow my account :)
