Im looking to purchase or build a ps4 controller with just rapid fire r1 l1 buttons, its needed for only 1 game. The game in question has a very buggy r1 l1 sequence that glitches out no matter how fast my finger hits the buttons it ends before i can even move the line, their is no fix currently to it and probably won't ever be fixed. With a rapid fire controller that line will max near instantly and so that's why im here. Im new to all this so i don't know much on what i need to purchase.
