Waveshare GameHat + Retropie + 3A+ GamePad doesn't work

[zuendy]

Hi,
sorry for my bad english.

I have a Waveshare GameHat (https://www.waveshare.com/game-hat.htm). It works great with Rasp PI Zero and Rasp Pi 3b with driver set from waveshare. But i want to work with PI 3A+

I installed Raspbian + Retropie and it works with an USB Gamepad.

But I would prefere the gamepad from Waveshare ;) , it's GPIO based with no standard Pinout.

So I installed the mk_arcade_joystick_rpi via

sudo /home/pi/RetroPie-Setup/retropie_setup.sh

under driver

Than I used this manual https://github.com/recalbox/mk_arcade_joystick_rpi

At first remapping:

sudo modprobe mk_arcade_joystick_rpi map=4 gpio=5,6,13,19,21,4,26,12,23,20,16,18, -1

Pins should be correct, later I found this pinout in another manual for recalbox here: https://www.instructables.com/id/Setup-Waveshare-Game-Hat-for-Recalbox-and-Kodi/

than Autoload for startup

sudo nano /etc/modules
insert: mk_arcade_joystick_rpi
 
sudo nano /etc/modprobe.d/mk_arcade_joystick.conf
insert: options mk_arcade_joystick_rpi map=4

command for testing inputs doesn't work, found no jstest

jstest /dev/input/js0

After reboot said emustation, gamepad ist detected, but the buttons have no function. :(

Can somebody help me and said what I made wrong?

Thx for reading.
