The Ultimate Atari Flashback! in Atari 2600 Posted May 7, 2021 Ok, I am setting up a RaspberryPi4 in a Atari Flashback case. I am using a 5v 4A power supply plugged into the flashback and have the power pins running from the flashback board to the GPIO. When I turn it on I get the lightning bolt. The instructions said to remove a capacitator and bridge the pins, but I don't see a compactor so not sure what to do now.
