If i keep a backup of replay.cfg file when updating system and overwrite it after first boot (when replayos partition was created), it keeps my previous options working except video output through gpio. I have to connect to an hdmi display (which I don't have nearby) to access the menu and change any of these two options manually (disable and enable again and reboot); this is the only way to get video through gpio again:
video_connector = "1"
addon_dpi_dac_pi5 = "1"
Setup:
- Device: Raspberry Pi 5 4GB
- OS version: 1.4
- Storage: NVME
- Power adapter: Raspberry Pi official
