Gaming • Re: Help with gpio buttons and image

Hi all,

I'm rather new to this but have been putting together a retro game system on the raspberry pi 4. I have a prebuilt (jaycar) cabinet that is plug and pay and has gpio. I have used a pre built reteopie image and flashed and have got it to boot...only issue is it didnt recognise the controllers.
I worked out I needed to install gpionext on the image to get it to recognise and had some success. It now recognises most buttons and 3 of the 4 directional pad.
Issue is, whatever I do I cant get it to recognise the up direction pad and 2 buttons. When pushed no input at all (not in emustation or in gpionext).
I have tried another cabinet and it's exactly the same which makes me believe it is something with the image and configuration.

Any advice on what I could check?
Thanks
Plug and pay definitely sounds like Jaycar. :)

If it's faulty on two units then I'd also assume a software issue.

What you could do is boot up a standard Pi OS image and test the GPIO. If the GPIO pins attached to the buttons change state correctly when you push them then it rules out a hardware fault.

According to the manual: "When you run the install script; it will then ask you if you want to configure a joystick
now, which you can do; make player 1 as joystick 1 (and for XC9062, make player 2 as
joystick 2 by running gpionext config again). The button presses won’t matter, as
you will have to re-configure from within Retropie by going to the Start Menu and
pressing “Input Configuration.” "

Do the buttons fail in gpionext and Retropie?
