I added the stick/buttons option because the D-pad is treated as a stick on a PS4 controller and buttons on a Wii U controller, so they can't use the same configuration.

The settings to match 2.50.2's behavior should be:
Code:
js_stick_1_x_stick = 0
js_stick_1_x_axis = 0
js_stick_1_x_offset = 0
js_stick_1_y_stick = 0
js_stick_1_y_axis = 1
js_stick_1_y_offset = 0
js_stick_2_x_stick = 1
js_stick_2_x_axis = 0
js_stick_2_x_offset = 0
js_stick_2_y_stick = 0
js_stick_2_y_axis = 2
js_stick_2_y_offset = 1
