Settings for HDMI and Composite

[dudumaroja]

retropie should detect what output you are using and let user decide what settings for retroarch to use on each, like audio drive or aspect ratio and more.

or a place in the config that would allow you to choose between hdmi / composite so all you would have to do is ssh in and change a line in the config to choose hdmi or composite out or just change it in x or the terminal and reboot.

In my opinion raspbian detects hdmi or sdtv if hdmi_force_hotplug=0 is set. runcommand.sh checks with tvservice --status if sdtv or hdmi is set.

https://github.com/retropie/RetroPie-Setup/blob/master/supplementary/runcommand.sh

runcommand.sh does something like this:
starttype/parameter 1 – if hdmi change resolution to CAE 1 (VGA), otherwise (SDTV) do nothing.

It is possible to add other CAE modes/resolutions. You can get a list of all supported modes withtvservice -m CAE.

what if I have my HDMI always connected but I want to hook up the pi to a bigger screen through composite ? all while the HDMI is still connected Is that possible?

[gizmo98]

It should be possible. The newest RetroPie-Setup script has an updated runcommand.sh. https://github.com/retropie/RetroPie-Setup/blob/master/supplementary/runcommand.sh

runcommand.sh 7 => composite PAL
runcommand.sh 8 => composite NTSC

It would be nice if someone could test these new options.

It is now also possible to set audio output from emulationstation (update-> source-based-installation/emulationstation).
