I stuck pics up....there the google photo links....my continuity is good as well...I'm gonna super clean my silicone pads......I've bought 4 sets of silicone pads but they all are from same manufacturer....
If continuity is good then there's nothing wrong with the PCB.

You can verify the pin numberings on the Pi with https://pinout.xyz/. The BCM or GPIO numbers are what's in the retrogame.cfg file. The physical pin is the just a numbering of the physical location of a pin.

Enrectangled in red are the physical pin numbering.

What you can do is test the GPIO inputs on the Pi for now.
1. Disconnect all the wires connected from the Pi to the tinkerBOY Controller 2.0.1 board. Or you can just disconnect all connect GND wires.
2. Power the Pi from the microusb port and turn it on. Assuming the Adafruit Retrogame software is running, get a jumper wire, touch one end to the GPIO5 pin on the Pi which is the 'A' button in the /boot/retrogame.cfg file and the other end to any GND pin on the Pi. You should get a response on the RetroPie screen when asked to configure inputs.

I've got this board also...
In the wiring diagram I saw that only one pwm GPIO port is used. Does it mean, it runs all the time in mono? So no Stereo output through headphone jack?

Both left and right audio can just be combined via settings.

ok, you missunderstood me: I want to know if the headphone Jack provides stereo sound. I can only see one low pass filter for one channel on the pcb.

as far as i can tell, the v2 and v3 board do just output mono sound (which is why he has those mix-down instructions, i would guess).

i think most 8/16 bit systems are just mono anyway (except genesis, notably), and with the single speaker anyway, mono usually gets the job done ok.

... dot matrix with stereo sound...!
My build should also become a playback system with kodi. so no stereo sound is poor.
