It works!!

I have made the following steps:

• Write the latest recalbox image on SD Card.
• Start the recalbox with gamehat and connect to your network.
• Use a FTP Programm (i used WinSCP) and copy the mk_arcade_joystick_rpi.ko on your recalbox to "/recalbox/share/system".
• Log into your Recalbox with SSH (i used Putty)
• Do following commands in your console without quotation mark:

"mount -o remount rw, /" Make the root path writable

"mv /recalbox/share/system/mk_arcade_joystick_rpi.ko /lib/modules/4.4.13-v7/extra/" Move and override the mk_arcade_joystick_rpi.ko file

"nano /recalbox/share/system/recalbox.conf" Edit the recalbox.conf

• Scroll to "D2 - GPIO Controllers" and override the line "controllers.gpio.enabled=0" to "controllers.gpio.enabled=1"

• Override the line "controllers.gpio.args=map=1,2" to controllers.gpio.args="map=5 gpio=5,6,13,19,21,4,26,12,23,20,16,18,-1"

• Save with crtl + O and enter

Following command: "shutdown -r now" Restart your recalbox

Now it should work.

Thank you for your help!

The guy has built a recalbox image which supports Game Hat. The download link is in the description and works great

This is my configuration on /recalbox/share/system/recalbox.conf

# ------------ D2 - 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
controllers.gpio.args="map=5 gpio=5,6,13,19,21,4,26,12,23,20,16,18,-1"

Please ignore Exclamation mark! I had to put it in front of it because the number sign puts the line as headline

Hey, here's a step by step tutorial: https://forum.recalbox.com/topic/15602/mapping-gpio-poru-game-hat/12

The "mk_arcade_joystick_rpi.ko" file can be downloaded further up in the thread.

Thanks again to the people in the thread.
