@cheungbx Thanks for your description! Tried that with 4.4.13-v7and always receive a segmentation fault after this: # rmmod mk_arcade_joystick_rpi # insmod /lib/modules/4.4.13-v7/extra/mk_arcade_joystick_rpi.ko map=4 gpio=5,4,14,22,13,18,21,16,6,20,26,12,18 Have a Pi 3b. Any ideas?

@rocketbomb If you "put back the semicolon" as you said earlier, you left "commented", that is: you have disabled this option. Now you say "saving it and uncommenting it", if you saved without the semicolon at the beginning, then you actually "uncommented", and left the option active. As I said in my previous comment: If there is an option starting with ";" or "#" in the configuration file, this means that the option is inactive. (In the file recalbox.conf it is easy to see this, there are "explanations" starting with "#" not to be read by the settings, and some commands disabled with ";" in case the user has problem, he just need to take the semicolon from front, it is not necessary to look for the right code to use.

There's a patch file I found that fixes the problem, but how do I apply it? Here is the patch: http://ithink.ch/blog/files/xin-mo/0001-hid-Add-new-driver-for-non-compliant-Xin-Mo-devices.patch

@marcobzh C'est bien ce que je pensai have fun with recalbox. Je met ton sujet en résolu

@subs I downloaded the full 0.78 romset and used it with Mame so I did not expect I have to check it if it's the right romset already. I will do a clrmamepro check and let you know.

i tried but it doesn't works for me on 4 beta 2 on rasp3 . even both keyboard and usb controller are configured and working and i set "default" for first player or second, usb and keyboard maps the same player (the first). should i open a new thread? thanks
