      @Milan What is the output rating of the charger ? Try another PSU. Also try writing the image again (did you decompress it etc ?), and try another sdcard also.

        @BuZz Where can I find the output rating? I tried with a chromecast charger too, still nothing, I've also tried multiple SDs. How do I decompress the SD card? Thanks for helping out.

          @Milan It's written on the PSU. eg 5v 2a etc.

          decompressing/extracting the image is detailed in the install intructions - https://retropie.org.uk/docs/First-Installation/#installation

            @BuZz I'm not sure which value I'm looking for, so I'm just typing the whole thing
            INPUT: 100-240V~50/60hz 0.2A
            OUTPUT: 5.0V=550mA

                @Milan The problem lies with your supply. You do not have enough current.

                  @rbaker The pi zero isn't in that table, what kind of current do I need?

                      @markyh444 I found a 5.2V 2.4A one, that should work right? It still doesn't work though.

                        The Pi zero could very well be fried. There's no built-in poly fuse unlike the Pi 3.

                        I've had a couple be bad right out of the anti-static silver bag and returned them to the seller.

                            @ivarwa I have done that multiple times, with different operating systems, NOOBS gave me error writing system partition, but at least it booted then. Now the light doesn't even turn on.
