      Are you running the cp command after running the game ? The log file is not persisted between reboots, so if you haven't run the game, there won't be any file.

      @mitu I only get one chance to open that menu... I start a game, then press A on the controller, then 'L - Launch With Verbose Logging'.

      that's fine, but if you reboot AFTER launching the game but BEFORE attempting to access the file, it will go away. try launching the game again and then try and get the file immediately and paste us the output of the failed commands please.

        Finally I have the file. This is outputted from the Vectrex emulator. I can not get one from the C64 emulator, as there is no way to shut the app down after using it, so the unit needs to be unplugged to come out of the app, meaning the log file will disappear...

          Your resolution is 4k@30hz. It's a bit too much too handle for emulation - I suggest you lower your resolution to 1080p@60hz.

          The Pi4 doesn't output 4k@60hz by default, if you want to still keep the 4k resolution, then enable 4k@60hz from raspi-config or add to /boot/config.txt:

          hdmi_enable_4kp60=1

            please format your logs correctly - see https://retropie.org.uk/forum/topic/3/read-this-first ('code blocks' section). i have edited your post this time :)

            Finally I have the file. This is outputted from the Vectrex emulator. I can not get one from the C64 emulator, as there is no way to shut the app down after using it, so the unit needs to be unplugged to come out of the app, meaning the log file will disappear...

            are you using escape key to exit? see https://retropie.org.uk/docs/Commodore-64-VIC-20-PET/

            as for your log, the problem is as i expected:

            [INFO] [Video]: Timings deviate too much. Will not adjust. (Display = 30.00 Hz, Game = 50.00 Hz)
            [INFO] [Video]: Game FPS > Monitor FPS. Cannot rely on VSync.
            [INFO] [Video]: Video @ 3840x2160

            you're using a 4k30 mode. select a 1080p60 resolution mode via raspi-config (available on the retropie settings section in emulationstation)

              Hi, I cannot change the resolution, when I go into Raspi-Config I select "2 Display Options", then "D1 Resolution", and it just jumps back to the first Raspi-Config screen, and thus loops around those two menus. I tried entering the code you suggested, but the audio is still slow and glitchy.

                @lektroid you can manually set the mode in /boot/config.txt

                for example, for 1080p on mine I use

                hdmi_group=2
                hdmi_mode=82
                

                you could try that or

                hdmi_group=1
                hdmi_mode=16
                

                these are the typical ones.

                  As an alternative to raspi-config, you can add to your /boot/config.txt file:

                  hdmi_group=1
                  hdmi_mode=16
                  

                  and remove the hdmi_enable_4kp60 line.

                      @lektroid How are you editing the file ? If you're using an editor from the PI, make sure you're using sudo when you start the editor, the file is not editable by the pi user, since it's a system file.

                        @mitu I'm plugging the SD into the mac, then using Textedit to edit the file (It's the only way I know), not sure how to use sudo?

                          You don't need sudo if you're editing the file on macOS.

                            So, what's the best way to edit it, since MacOS won't save the file?

                              Just edit it from the Pi. Exit EmulationStation and then run

                              sudo nano /boot/config.txt
                              

                              to edit the file. Reboot after saving the file, by running sudo reboot.

                                @dankcushions Thanks for your reply, but this is not working. I have followed the instructions to the word, inserted all the information into Cyberduck exactly, there is nowhere to add an IP address in Cyberduck, so obviously I could not enter that, and it refuses connect.

                                there sure is - i use it myself:

                                b0b38c87-379d-495c-98a2-ad0be5c03490-image.png

                                Open Connection > Server prompt.

                                I have this running now, thanks for the image, I was entering a server name where the IP should go.

                                However, I still cannot save the file, it says "Permission denied. Please contact your web hosting service provider for assistance." and refuses to overwrite.

                                How can I give permission to the file so it will save?

                                  @lektroid it looks like the file is owned by root and i'm not sure how to give cyberduck sudo - i don't use it for editing files, just accessing and transferring. i would follow @mitu 's advice as to how to edit it via commandline.

                                    @dankcushions I'll have a go, but I'm no commandline guru, hopefully I can work it out.

                                    I'm just confused as to why I am unable to access the screen resolutions from the Display Options menu, is something broken?

                                        Hi. I'm popping in late on this one but I wanted to point something else out to you while you travel down the Retropie path. Unlike other single source software that is written by one person and constantly updated by the same... Think or Retropie as a huge umbrella that a ton of individuals came together under to get all these emulators to work with each other.

                                        Many of the emulators have been tweaked to specifically work in the Retropie world, so it will pay you back 10 fold to start to become familiar with some Linux commands and how it works. Don't have to be an expert, but as you add emulators and what they need to work, it will help a lot.

                                        Download Putty and if you are using a PC WinSCP. They are for getting straight in to the PIs file system and working with it. You can use a Mac, but again, it's not always the same as just using mac files. Linux requires permissions to be changed on folders, files..etc.

                                        Also... Commodore 64... If you are using Vice, there is a great video on youtube by a guy named ETAPrime who shows you how to configure the buttons to work the emulator. There is also lr-vice you can download sperately that will pickup the standard Retroarch joystick button commands.

                                        Either way you'll need to read and research many of the emulators as you add them. Many need special configurations to use properly. Take one at a time. I have 43 systems running on mine. Took me almost a year to get them all working correctly...or as best that I could.

                                        Good luck, come back often to ask questions. You're only 'incompetent' because you don't have knowledge. Knowledge is all about effort. Max effort = max knowledge.
