Making my handheld built on a Pi Zero recognize the onboard control buttons.
-
Hello. I am having a devil of a time with this handheld system I bought a couple years ago..
It was a Coolbaby system built on a Raspberry Pi Zero. It came with a built in Micro SD card full of roms and of course the image was all preprogrammed to run with the built in control buttons on the system.
The main problem with the system is that most of the game names are in a language I don't recognize so I was trying to just start from scratch and install Retro Pie from the ground up on a new Micro SD card.
When I wrote the image to the card and plugged it in, Emulation Station or Retro Pie or whatever won't recognize the built in controls that are part of the circuit board. It will detect my SNES style USB controller and my wireless keyboard with a built in mousepad, but not the control buttons that are built into the game machine itself.
Does anyone know what I'm talking about? Can anyone help me? My goal is to set this system up from the ground up with ROMS in languages I can understand and use it again.
Thank you for whatever help you can give.

You'll need some additional setup or driver for the circuit inputs - is the Pi board connected via GPIO to the circuitboard ? What model is the handheld - maybe the vendor has instructions on how to configure the inputs on a bare RaspiOS installation.
