How to edit /boot/config.txt ?

Jesse

Hi

How can I access config.txt for edit composite video on rapsberry pi?
Thank.

On windows you can just put your micro SD card in the PC and browse to the file.
Or you can edit it at the command line if you connect via SSH

nano /boot/config.txt

@Jesse better use sudo nano to edit the file: sudo nano /boot/config.txt

Now I found config.txt but how can I change HDMI to composite video by config for small portable DVD player?

Will all games work on composite video?

Last time I was try start games on composite video by RecalBox but games wont start up and I didn't get help from recalBox forum that why I move to RetroPie

Thank

Jesse.

look for this line #sdtv_mode=0. Change it to one of the following as per your type of TV/Monitor. I have it set to Normal PAL.

sdtv_mode=0    Normal NTSC
sdtv_mode=1    Japanese version of NTSC – no pedestal
sdtv_mode=2    Normal PAL
sdtv_mode=3    Brazilian version of PAL – 525/60 rather than 625/50, different subcarrier

Next thing you need to add is hdmi_ignore_hotplug=1. Make sure that hdmi_force_hotplug=1 is commented out. Now this is the setting you should keep in mind always. You will have to switch back this setting if you ever plug-in your Raspberry Pi with HDMI. Better to write both and just comment out one of them with #symbol.

Go to RetroPie menu > Audio > 3,5 mm Jack

Another way to edit /boot/config.txt is by plugging in a USB keyboard to your Raspberry Pi and pressing F4 to exit EmulationStation to the command prompt and then type

sudo nano /boot/config.txt

After you're done editing you can use keyboard shortcuts such as Ctrl+O to save a file and Ctrl+X to exit.

You can also test audio with this command:
speaker-test -c2

press Ctrl+C to stop the test

Another couple of ssh options, assuming your Pi is networked:

From an android device, use JuiceSsh. This is an excellent remote shell tool, and free
From Windows, use PuTTY.
