      @Drdave79 please send us the requested information in https://retropie.org.uk/forum/topic/3/read-this-first including verbose log, and indeed please send the /boot/config.txt with the overclock removed (as there is little point diagnosing issues with an overclock applied)

        @dankcushions Here's the config file. I'll get the rest shortly. It says I don't have enough privileges to upload the file. The cut and paste is a little wonky.

        # For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=1
hdmi_mode=4

# uncomment to force a HDMI mode rather than DVI. This can make audio work in

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display

          @barbudreadmon No glitches when running those other games. I did check and I'm running at 1280 x 720 @ 60 Hz n/a (74.25 Mhz, phsync, pvsync, userdef) if that means anything.

            @dankcushions When I run the game with verbose logging, exit the game, and check the /dev/shm folder, I see no log file. Only mono.513 file.

                this is not possible in a standard retropie install. you're not rebooting before looking at the folder, I hope?

                What is the output of ls -l /dev/shm/ ?

                  Meaning you probably can't run content at odd refresh rates for some reason, maybe something about your retroarch video synchronization settings ?

                    @dankcushions Nope. I launched the game with verbose logging. Played it for about a minute. Excited the game and checked the folder.

                    When I run that command, I get mono.520

                          @dankcushions I now have a runcommand.log but it's empty.

                              @Drdave79 again, you should make sure everything is fine with your synchronization settings, maybe you need

                              video_vsync = "true"
vrr_runloop_enable = "true"

                              ?

                              Edit: also note that i just added a core option to force 60Hz, however you should only consider this as a last resort workaround since it'll make games run faster than they should...

                                in what sense? the last logs you have posted have just been pasted directly - you just did it again now!

                                i appreciate this hobby can get technical and isn't always intuitive, but to support people in the least amount of free time there's lots of documentation and specific instructions on how to seek support.

                                read this first says about logs:

                                Format your posts! - put small logs in code blocks - see http://commonmark.org/help/ - and put large logs on a pastebin type site like http://paste.ubuntu.com/ http://pastebin.com/ or similar.

                                there's 3 options there, all of which are better than just pasting logs/configs directly into the forum (although even that is better than not posting them at all..). please read carefully the read-this-first page next time you seek support, which appears to be quite frequently. there is better things we could all be doing than repeating what has been said at the top of every forum page.

                                  retroarch.cfg

                                  i can see from this that you didn't run with verbose logging via the runcommand, although it should still generate the file regardless (and you still haven't run the command like i instructed). you should also paste all relevant configs, /opt/retropie/configs/arcade/retroarch.cfg, /opt/retropie/configs/all/retroarch.cfg (note: codeblocks, pastebin, etc etc)

                                  but yeah, what's all these video settings? they're not stock.

                                    Are you referring to:

                                    retroarch.cfg

                                    video_refresh_rate = "60"
                                    video_fullscreen = "true"

                                    video_fullscreen_y = "720"

                                    ...? This is their /dev/shm/retroarch.cfg, automatically generated here at runtime; mine is identical to this (I am using a 720p TV.)

                                    ...unless you mean the:

                                    hdmi_group=1
hdmi_mode=4

                                    ...in their /boot/config.txt; those, indeed, are not stock.

                                      @sleve_mcdichael Thank you Sleve for helping to clarify. I'm not trying to be difficult at all. I've always appreciate everyone's time here. But yes, I did run the command and report back as @dankcushions has requested. He must have missed my response.

                                      @dankcushions I wasn't aware I had to run verbose logging via runcommand. But even you admit that it should still generate the file either way. I can definitely add the additional logs you requested from pastebin. I will do that shortly.

                                      If my /boot/config.txt isn't stock, where can I obtain the correct file to avoid more problems?

                                        @dankcushions I must not be using pastebin.com correctly. I paste the log into the top. I give it a name and click create new paste. Then I hit copy raw which places it in the clipboard. Then I paste it in this forum. I don't want to continue to frustrate you.

                                          I wasn't aware I had to run verbose logging via runcommand.

                                          Yeah you have to enable it each run, or you could enable it permanently in /opt/retropie/configs/all/retroarch.cfg with:

                                          # Enable or disable verbosity level of frontend.
log_verbosity = true

                                          If my /boot/config.txt isn't stock, where can I obtain the correct file to avoid more problems?

                                          You can extract the file from the stock SD card image using 7zip on your PC.

                                            I hope this works.
