The ps4 system itself remaps to l2 and it works?ah, that's a thought. i wasn't able to complete statik because of that bug. ...i can confirm that both of my controllers can't hit "255".
That's pretty funky. Do you have another ds4 to test? R2 is an analogue button so maybe the game is wanting a 255 push but only getting a 254.
