Plutonium

FragsAreUs I used to use steam but when the new pluto update came out you have to load the came through the pluto launcher instead of steam so now i cant use steam. Ive tried so many programs that remap your conroller buttons but none of them work ive honestly ran out of ideas lol.

FragsAreUs I tried that and it doesnt work.

Is there anyway to use L1 to aim and R1 to shoot on a ps4 controller instead of using L2 and R2? If so how?
