@Dragu I did not fully understood your schematic, i already bought the relay and now I'm planning on getting the PCB to create the interface. I believe i understood the philosophy behind. Basically you insert one token and it flags on both encoders. But in that scenario 1 coin gives always two credits. So if this thinking is correct you would be fine to use @tong-man solution with a split wire at the end, so I can connect to both GPIO pins, no?
Hello @tong-man, i noticed that the link mentioned above was developed by you and reference on your youtube channel. I noticed that your bartop as two players. So my question is: When you insert a coin your credits are assumed as 'general credits' and both players can take them?
Thanks in advance for the support.
@kjbstar Thanks for the input. I´m afraid there is no way to use a single coin acceptor to replace both buttons. If there is any other information that someone can have will be welcome.
Gents,
I’m building a arcade table using Recalbox. My system is fully working. I was thinking on adding a coin acceptor to it for fun. But I could not found any thread on this matter. (Inlight me if already exist)
The current setup has two players and uses a two independent buttons for insert coin on each player. What I want is to replace this buttons by a single coin acceptor?
I know that is possible with retropie in parallel with a zero delay card. However, I want to connect it through GPIO. Probably I would need to have an independent energy source as it is 12v.
Thanks in advance for the support.

@DCLAIRAC Ignore the above is sorted the wiring will test and post my feedback. Is much simpler than both of us thought I believe, if we understand the micro switch schematic NC (normal closed) vs NO (normal open)tells you everything.
@dclairac thanks for the support.
And apologize for the late answer but as I work offshore no access to the normal world.
So basically we have just to test with a multimeter and understand the impulse constant or partial.
I never used the multimeter, read a bit and understand that if we set it up incorrectly we may end up burn it. Can you let me know the setup used and the test performed?
Regards
Ivo
@Substring i'm still troubleshooting the system there are the following situations occuring:
@substring as i will travelling home at that time can we make it sat**day (11th)? Or sunday.
Wiring you mean positioning within the GPIO? If that would be the case we still would have the response when mapping. And the problem is that some of the games work and the buttons work..
@substring was 4.0 because I could not found roms... so i was using a compile file to try some games.
Changed to the 4.1 and did the support archive, same problems regarding the mapping. (https://file.ac/DaGZwV_MA-U/)
Can we discuss roms subjec on Kiwi IRC? Let me know when suits you.

@substring after some more testing this occur within Neo Geo, Name, PlayStation. I can play some games of Nintendo not all.
Support Archive is a separate topic? (Sorry for the noob questions)
@substring so I setup my buttons, initiate a game. And then when I have a game loaded at the insert coin (metal slug) or 1 player game (mario) there is no response from any button. I do not have an hot key specific button.
I tried once again to remap my buttons but it does not work as mentioned above.all the wiring is ok as per schematic.
Any thoughts?
@substring yes basically none work after A is assigned.
How could P1 or P2 affect that? I’m using the GPIO layout proposed within the wiki.
Is there a way within evtest to understand that the button is assigned to the correct GPIO pin?
@substring so this what i do:
Main Menu/ Controller Settings
2 Gamepads detected (picture below)
Press A and start the configuration (joystick configured - Picture below)
@substring going to start drilling the button now! 
I just noticed that when i push up it goes down... so may be there is a issue on the setup of wiring.
However, I did a run on remapping but it still does not recognise after A button 
Thanks
@Substring All buttons responding. Seems incorrectly setup though. Shall I remap them?
And what have i done... with the commands you suggested?

Note: The joystick works withing the recalbox. But none the button work still.
@Substring output from the evtest below.
Sequence was: js up; js down; js left; js right; B; A; TR; TL; X; Y; Start; Select.
So i would imagine that all the setup is ok. However, within the Recalbox is not detected.
I have a daisy chain ground that runs on all the buttons and is connected to the GPIO 6 any potential issue with that?

@Substring so i did a evtest GPIO detected as within recalbox. All buttons worked (how can i save the log of events to share with you?)
I even did a wiring direct to the GPIO for individual buttons to remove the wiring possibility (e.g daisy chain ground).
Any other ideia?
