Configuring evdev RPCS3 joysticks

The evdev joystick code in RPCS3 is primarily designed to use XBox controllers by default. For other controllers, you'll probably need to make a few changes.

The config file

Configuration is stored in $HOME/.config/rpcs3/config_linuxjoystick.yml. The easiest way to test your joystick is with the PS3 Game Pad Test homebrew.

Axes

If you're not using an XBox controller, and your joysticks flat-out aren't working, try adding this to the config file:

Axis scaling: false

In addition, if when using one of the joysticks, the trigger buttons (e.g. R1/R2/L1/L2) are pressed down, add this:

Z axis triggers: false

TODO: Remapping axes.

Buttons

Use the evtest utility on your joystick, e.g. evtest /dev/input/by-id/my-joystick, and note which buttons are sending which button codes. You can then remap the buttons using this syntax:

Select: 8
Start: 9

Triangle: 0
Circle: 1
Cross: 2
Square: 3

R1: 7
R2: 5
R3: 11
L1: 6
L2: 4
L3: 10

You don't need to remap all the buttons; just do the ones you need to change.

D-pads

Some controllers set the D-pad to be configured as an extra hat. In this case, RPCS3 will work out-of-the-box. However, if your controllers sends D-pad events as buttons instead, then note the button codes (see the Buttons section above), and add them to the config file like so:

Up: 1
Down: 2
Left: 3
Right: 4

Example

Here's an example config file for a PS2 controller:

Axis scaling: false
Z axis triggers: false

Select: 8
Start: 9

Triangle: 0
Circle: 1
Cross: 2
Square: 3

R1: 7
R2: 5
R3: 11
L1: 6
L2: 4
L3: 10
