I recently downloaded a Batocera image that does not have PIRONMAN5 when you do /etc/init.d/S92switch setup so I looked into the rpi_gpioswitch file and it is missing PIRONMAN altogether. I found the updated rpi_gpioswitch on a github, but I don’t know how to copy and paste from my windows browser into powershell and nano editor to update it.
Sorry, there doesn’t seem to be a way to modify this file directly, you may need to reinstall the system. Suggest asking in the batocera forum.
