      Very simple layout that works well.

          Hello! Where this command line should be inserted to interlace the signal ???

          Thank you! :-)

          $ Tvservice -c "NTSC 4: 3 P"; Fbset -depth 8; Fbset -depth 32; Tvservice -s

            I am just wondering, does this firmware still need to be downloaded from the google docs link, or is the original pi-firmware on board with 240p over composite now? I have updated my pi and wonder if I need to reinstall firmware for 240p. Thanks

              @ohmycommodore said in Output 240p (instead of 480i) on composite RCA:

              I suppose the eventual goal might be to establish a 240p tweak for the games for composite out, while maintaining 480p or similar for the menus to keep them sharper.

              Excellent idea, I'd love to see that. 240p on a CRT TV still remains much better than any shader possible.

                And certainly down the line it would be wonderful to have something like this as a toggle within the system itself. A "select your desired output and restart" type thing.

                  Still cant figure out or find out...

                  Does the 240p firmware linked in this thread still need to be manually installed on new and updated Retropie builds?

                  Sorry to be a nag, just can't find an answer. Thanks.

                    @nitrogen_widget so question with the tv service stuff you posted. do we still need to us popcorn mixes stuff? and can i put the tvservice things in runcommand-onstart.sh and runcommand-onend.sh? or where would i put them? or do i have to do this in command line everytime?

                      @edmaul69 Popcorn mixes updates to the firmware are just part of the normal raspian package now, all you have to do to enable the progressive output is update raspian and set one of these 2 parameters in config.txt:

                      sdtv_mode=16 # progressive NTSC
                      OR
                      sdtv_mode=18 # progressive PAL

                      As for the runcommand_onstart/end commands, i think those are for switching back to 480i in emulation station so the resolution is easier to read (es in 240p, even with a decent theme is terrible haha)

                      Anyway, im curious as to where those go too.

                          @edmaul69 I'm not sure if the update you did does it. Try adding that parameter above to config.txt and rebooting. you will know immediately if it's outputting 240p or not, the console text will be unreadable in 240p mode and ES and emulators will have scanlines.

                          The reason i havent been using it is i cant figure out a way to get a perfect scanline, it seems the scale is off and the pixels are not fitting the scanlines at a 1:1 ratio. The best way to tell is to play megaman games, the power bar is supposed to be alternating white and black pixels but it looks line doubled and line skipped. So until i can figure out an output scale that works correctly, i haven't enabled it yet.

                            @capeman i ended up do it all the old way. But not sure if it mattered or not. It didnt do anything until i ssh'd in and ran the command for progressive which i should gave tried first. Now if we can get a way tomake it change back and forth automatically would be cool.
