l2/r2 analog stick board

[nuke_arg]

Good evening, I write from Argentina, first of all thank you very much for your effort in this version, my query is as follows, I have RECALBOX 6.1.1 installed in my bartop, and I want to make the L2 and R2 buttons work in my gpio, but I cannot make them work, i need this setting is it possible?

#this next line is for use with 4 extra buttons (maybe L2, R2, C, Z)
options mk_arcade_joystick_rpi map = 4 gpio = 4,17,27,22,10,9,25,24,23,18,15,14,2,19,26, -1, -1 hkmode = 2

I've also tried replacing the original mk_arcade_joystick_rpi.ko file with mk_arcade_joystick_rpi.ko from THEFLAV but it didn't work.

To be clearer, the only thing I need is to add L2 and R2 to the driver with that GPIO configuration.

thank you very much in advance
