      Hey all not sure how or when this happened but now I cannot change the default resolution for my emulators in retropie.

      I can change it for the "emulator+rom" but whenever I attempt to change the default resolution for the emulator the following error message pops up in the lower left corner:

      "sed: couldn't open temporary file /opt/retropie/configs/all/sedHWtTcS: Permission denied"

      Any help is appreciated here so I don't have to setup the resolution of my roms manually one by one. I have already tried installing retropie again as well as updating all packages. Neither worked.

        @k-shaps Are you attempting to do this from the runcommand menu?

          No, I am doing this from within the launch menu of the game after selecting it from within retropie under each specific emulator. Is there a better way of doing this? Very much a noob when it comes to this. Thanks!

            @k-shaps In Emulation Station go into the RetroPie menu and choose Configuration Editor then choose option 1 Configure basic libretro emulators (or something similar) It might work that way. If not you may have some file permission issues.

              @AlexMurphy that didn't work but thanks for the suggestion. How do I go about changing file permissions? Is there anything that would have preempted this? Retracing my steps I can't for the life of me figure out why my pi3 is doing this.

                @k-shaps Try this sudo chown -hR pi:pi .emulationstation

                  @AlexMurphy I pressed f4. Entered this and nothing happened. I waited a few minutes and then unplugged my pi and replugged it in. Nothing has changed. Did I miss a step?

                    @k-shaps Try this sudo chown -R pi:pi /home/pi reboot then try the resolution settings again. When you enter the command nothing should happen apart from the command prompt refreshing.

                      @AlexMurphy just to make sure I'm not messing up what is the proper way to reboot after entering that? Is their a command for that? Up until now I have always just unplugged and replugged in my pi3.

                        @k-shaps I just tried entering that as well; following it by rebooting via the command "sudo reboot" still nothing. Depending on the emulator I get the same error message with a variation after the all/ in the above error message.

                          @k-shaps Have a look at this. https://retropie.org.uk/forum/topic/2407/can-t-select-emulator-for-rom/2

                            @AlexMurphy I tried "sudo chown -R pi:pi /opt/retropie/configs" and that did nothing. Anything else you recommend? Also do you know how this could have started? I can't seem to figure out what I could have done that would have changed this. Before I had all my emulators running CEA-16 with no issues.

                              @k-shaps If the link above did not work then no, sorry. Probably best to start fresh.

                                @AlexMurphy Thanks! Two more questions - I didn't follow that thread all the way through in terms of using 777 for folder names and permissions as I don't know how or where I can do that. Is there an easy guide that I can follow perhaps with screenshots or a video? Also if I do need to start fresh exactly how would I go about doing that?

                                  @k-shaps you should not need to do any chmod 777 ever and it's a bad idea too (makes no sense on files - since you don't want executable bit set, and also sets writable by anyone).

                                  All user editable stuff should be owned by the user retropie was installed for - eg pi.

                                    @BuZz Thank! Still a bit confused on this "All user editable stuff should be owned by the user retropie was installed for - eg pi." Where can I go to edit this or change the permissions to allow for the emulators to accept my default resolution changes?

                                      @k-shaps if using the image - the /opt/retropie/configs/all should be owned by pi - the command mentioned above chown -R pi:pi /opt/retropie/configs should make sure all configs have the correct ownerships.

                                      Not sure why you are getting the error once that has been done, unless something is changing it - a 3rd party script or something else (I don't know of any issues in retropie that would cause this - there was some old bug but it was fixed a while ago).

                                        @BuZz Sorry, really a noob to all this - how can I even get to that to make sure it's correct? Like where is /opt/retropie/configs/all and how do I go about editing it? Can I do this with WinSCP via SFTP or does it need to be done all on the pi? If so I don't have the first clue on how to do this. Any help would be great! Thanks!

                                        /opt/retropie/configs/all is a folder - where it is ? that is where it is :-) that is the location

                                        If you mean how do you access it - see

                                        https://retropie.org.uk/docs/SSH/

                                        ls -la /opt/retropie/configs/all

                                        will show current permissions.

                                        Can access the folder via windows networking also, and via sftp.

                                          @k-shaps Thanks Buzz! I'll give this a whirl when I get home from work tonight. Hope this works!
