No problem. No additional hardware is needed, it’s all done over SSH. You can read more about how to make the changes on the firmware post linked a few posts earlier.

Cheers G30FF, I will be giving it a go when I get home from work!
I will stick to the basic firmware initially but hopefully will be able to edit it more once I get a little more confident.
I like the fact you can have an additional controller for games consoles that require more buttons!
G30FF, if you have time could you possibly guide me through the commands I need to use to send the serial config you included in your first post?
I have updated the firmware to v2.3 (picade.hex) and as I don’t currently have any additional controllers I think that config would be ideal for MAME use.
EDIT: Does this look correct once connected to the Pi3 via SSH?
import serial
picade = serial.Serial(‘/dev/ttyACM0’,9600,timeout=1.0)
picade.write(“a 220 221 222 223 230 231 232 233 234 235 236 237 176 177 250 251 105 111 112”)
print(picade.readline().strip())
Honestly, my instructions would differ from yours, since I just did mine completely over SSH without using Python. Not exactly the best way to do it, but it worked for me. To do that, I opened a screen session using:
screen /dev/ttyACM0 9600
Then I pasted the following into the session:
a 220 221 222 223 230 231 232 233 234 235 236 237 176 177 250 251 105 111 112 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
Then press “s” to save, then press Ctrl+a, then “:”, then type “quit” to exit the screen session.
Thanks,
Can I just confirm your Picade PCB is only connected to the Pi via the USB lead throughout the process?
I am connecting to the Pi via a Wi-Fi connection from my Mac (ssh pi@retropie.local) and then just sending the commands from there.
That’s correct. The Picade PCB is only connected via the USB.

Just to sum this whole thing up for me:
I finally set the pcb into Gamepad-Mode using the serial Monitor in the Arduino IDE. Then I configured the controls in Emulation Station. After that things went wrong. lr-mame2003 didn´t recognize any buttons, whereas Emulation Stations UI did work flawlessly. I tried several things, setting the driver to udev, sdl, sdl2 and whatnot, editing ArduinoLLCArduinoLeonardo.cfg as stated in the original post, trying this in retropie 3.8 and 4.1 and so on.
I didn´t get it to work, so I switched back to keyboard mode. After that I did try to map the keys of Defender and MK using mames tab-menu (did connect an extra keyboard for that) and not the RGUI of retroarch. This did work perfectly, I finally have working and playable configurations for all my critical games using more than two buttons :-). Conclusion for me: retroarchs per game remappings don´t seem to work, mames built-in menu is key to success. One last question: does anyone know where the keymappings I generate with the tab-menu are stored? I searched around the /opt folder but couldn´t find any clues.
Happy Retro Gaming …
Check in ~/RetroPie/roms/mame-libretro/mame2003. Or check ~/RetroPie/roms/arcade/mame2003 if you put your games there instead.
Found them, thanks you.
