Map dualsense controller manually and disable Steam Input

This fixes the issue of swapped buttons and Triggers in the dualsense controller opening the pause menu The issue is caused by the SDL version used by hollow knight not recognizing the dualsense controller and mapping buttons properly. It is also not helped by steam input not disabling the native controller support when used in hollow knight. The issue cannot be fixed by simple mapping in steam input.

1. Disable Steam Input
2. Set the following as launch option

SDL_GAMECONTROLLERCONFIG="050000004c050000e60c000000810000,Sony DualSense ,a:b0,b:b1,back:b8,dpdown:h0.4,dpleft:h0.8,dpright:h0.2,dpup:h0.1,guide:b10,leftshoulder:b4,leftstick:b11,lefttrigger:a2,leftx:a0,lefty:a1,rightshoulder:b5,rightstick:b12,righttrigger:a5,rightx:a3,righty:a4,start:b9,x:b3,y:b2,platform:Linux," %command%

Use libSDL2 from Steam runtime:

If the above doesn't work. Try the following.

You can also try making the game use libSDL2 from Steam runtime

SDL_DYNAMIC_API=/home/USERNAME/.steam/root/ubuntu12_32/steam-runtime/usr/lib/x86_64-linux-gnu/libSDL2-2.0.so.0 %command%

(where USERNAME should be replaced with your OS user name)
