I think that the problem is finaly solved. The last 7-8 days i have removed my bartop cabinet and put it away from my wifi router and laptop. I don t know yet which of those two caused the hole problem. Anyway everything it s OK now. Thank you very much for your help and support. Thank youuuuuu!!!

@dragu i had the problem even with the jack unpluged. I put the cabinet to another place away from the internet router and laptop to see if this is the problem.

I have changed everything. Pi, micro sd, encoder, joysticks, all the cables including the power supply of the pi. All except buttons and screen. Generally i made the two cabinets with exactly the same way and i have the problem only in mine. Substring what does "generic ground problem" means? And what is the conclusion of the evtest i attached?

Here is photos of my setup. I have built two identical bartop cabinets https://postimg.cc/gallery/20r8hezj0/026a7816/ with different screens one for me and one for my brother. Only mine has the problem. I replaced everything from my cabinet. Now the second player is unplugged. https://postimg.cc/gallery/10wc7yuzg/eff0777a/
I have followed directions from here

Ps. I have my cabinet over my laptop and near my router. Is it a problem?

@substring here is the evtes during the problem https://postimg.cc/gallery/2t129wh3w/b01e24f1/
And still is writing and writing and writing

@substring i realy don t know. But i have the same problem even without connection at all

@substring so i guess this is not the broblem?

@substring i tried yesterday to run evtest when the problem began again but i noticed that the pie was out of internret connection. Then i tried to connect to my wifi and i saw instead of my wifi key this https://postimg.cc/image/ilx9c1jkn/343a9b6e/.
I didn t touch anything. I think that if i manage to put my wifi key and connect to my wifi i will solve the problem. But temporarily. Can you think what is going on now?

@substring when the problem began i had those inputs even with the xin mo unplugged. Now i haven t try it again. I have already replaced the whole xin mo set exept the buttons, the raspberry pi , the sd card and all the cables. The only thing i haven t replaced yet is the screen because i haven t a second one. But i still have the problem. And it begins after 2 or three hours or more after switching on the console and not from the beginning. I made a second bartop cabinet with the same setup for my brother with no problem at all. Mine bartop has the problem. I am so desperate!

@substring here it is.

Hello again. I install the official recalbox image but i still have the same problem. Here is what is written to recalbox.conf. The gpio controllers are already set to 0. Do i have to put # in the beggining of the sentence?

------------ D2 - GPIO Controllers ------------

GPIO Controllers

enable controllers on GPIO with mk_arcarde_joystick_rpi (0,1)

controllers.gpio.enabled=0

mk_gpio arguments, map=1 for one controller, map=1,2 for 2 (map=1,map=1,2)

controllers.gpio.args=map=1,2

@oyyodams thank you very much. I hope with the ofdicial image to solve the problem.

@substring i am really sory but i didn t know that it was unofficial. I just made a resaearch for a recalbox image 32 gb like my sd card. I am not so familiar with all those things. I ll try with the official way. Anyway thank you very much for your help.

@substring i have this image to my sdcard https://www.youtube.com/watch?v=kklTCp8HZBo and i can t find to the menu the recalbox webmanager to edit recalbox.conf. I tried from the config text but i didn t find "controllers.gpio.enabled"
I made two arcade cabinet with the same setup and i have this problem only in one of them. Do you thing that if i disable the gpio driver i will fix it?

@substring how do i continue to event 2 or 3? And sorry but i didn t understad your question. I use the xin mo set - 18buttons. I bought it from ultracabs while i was following orders from here http://www.instructables.com/id/2-Player-Bartop-Arcade-Machine-Powered-by-Pi/ . Ps. Thank you for your patience with me and for your answers and realy sorry for my awful english

@substring thank you very much but i need additional help. I run evtest then i press 0 and then i don t know what to do. How can i understand if some events are happening by themselves with no user action?

@substring can you please give me directions how to run evtest because i m not so familiar with this. Thanks in advance
