I'm just upgrade 5.25 rc3 form 5.24.
gpio can't not work.
setting:
------------ D3 - GPIO Controllers ------------
GPIO Controllers
enable controllers on GPIO with mk_arcarde_joystick_rpi (0,1)
controllers.gpio.enabled=1
mk_gpio arguments, map=1 for one controller, map=1,2 for 2 (map=1,map=1,2)
controllers.gpio.args=map=1,2
