I have to hold Power Switch

[CameraGuyKurt]

I would suspect a bad connection to the Pi. I wonder if there’s a bad solder joint on the pin that controlls the power on/off feature. Can you send a photo of the Pi and it’s solder?

Hi there,

I've just completed a build and I'm having the same problem. I'm using the hammer header and all the connections seem good to me. The solder around the switch seems good as well.

I've gone through the troubleshooting steps of checking the batteries and their connections. With the batteries removed and USB power connected to the FPAzero charging port, the charging LED lights up green. With batteries installed the LED shows blue while charging, then green as expected.

EDIT: I am also using the disk image from the FreePlayZero website, not stock RetroPie.

I'd appreciate any suggestions,
