      • Pi Model: Raspberry PI 4 8 GB
      • Power Supply used: 4A USB C Power Adapter
      • RetroPie Version Used: 4.8
      • Built From: Retropie image from Raspberry Pi Imager.
      • USB Devices connected: Logitech Wireless Keyboard
      • Controller used: USB Wii Pro Controller
      • Error messages received: No Error Messages, Games just go to black screen and revert back to EmulationStation
      • Verbose log (if relevant): log attached below. Can create a verbose log later if needed.
      • Guide used: NA
      • File: /opt/retropie/supplementary/runcommand/runcommand.sh: line 1319:
      • Emulator: lr-mupen64plus-next
      • Attachment of config files: /dev/shm/runcommand.log file pasted below.
      • How to replicate the problem: Simply play a rom. Most of my issues are experienced with Legend of Zelda, Ocarina of Time, and it seems that the game crashes more frequently when I get to new locations in the world, as opposed to staying in one place. Rendering new rooms in the world, saving and loading saves also tend to cause more crashes.

      With the above details out of the way, I'll provide a bit more info about my problem. I have a fresh install of RetroPie on my raspberry pi 4 8gb model, on a 64 gb sd card. The power supply is 4A that shows me no signs of issue. When playing N64 games, mainly Legend of Zelda, Ocarina of time, I've found that the game will be playable for approximately 5-10 minutes before suddenly crashing to a black screen and reverting back to emulation station. I receive no warnings or errors when the game crashes. When launching Roms with lr-mupen64plus-next, it prompts me to view /dev/shm/ for log files, which I have done after having numerous crashes. Below is the output of one such crash in the runcommand.log file.

      Parameters:
Executing: SDL_VIDEO_KMSDRM_CRTCID=87 SDL_VIDEO_KMSDRM_MODEID=40 /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mupen64plus-next/mupen64plus_next_libretro.so --config /opt/retropie/configs/n64/retroarch.cfg "/home/pi/RetroPie/roms/n64/Legend of Zelda, The - Ocarina of Time (U) (V1.2) [!].v64" --appendconfig /dev/shm/retroarch.cfg

/opt/retropie/supplementary/runcommand/runcommand.sh: line 1319:  1467 Segmentation fault      SDL_VIDEO_KMSDRM_CRTCID=87 SDL_VIDEO_KMSDRM_MODEID=40 /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mupen64plus-next/mupen64plus_next_libretro.so --config /opt/retropie/configs/n64/retroarch.cfg "/home/pi/RetroPie/roms/n64/Legend of Zelda, The - Ocarina of Time (U) (V1.2) [!].v64" --appendconfig /dev/shm/retroarch.cfg

      It seems that every time an n64 game crashes, the Segmentation fault at line 1319 is present in the log file, with a different 4 digit number after the line 1319: in each crash instance.

      Some things I've tried:

      • Update retropie in the retropie setup script.
      • Update the n64 emulators in the retropie setup script. I've tried both from Binary and from sources, no change.
      • Attempted to use a different game controller than the usb wii pro controller.
      • Tried some different N64 games.

      All of the above things I've tried have yielded no change in results. the segmentation fault crashes seem to be quite regular in ocurrence, but do seem to happen more frequently when getting to new locations in the world of these games.

      Any advice on how to further troubleshoot this issue? My next step is to attempt another fresh install of retropie and to load only one game to attempt it that way.

        • Do you have an overclocked system ? Then remove the overclock and try again.
        • Use an official power supply - funny things happen when thre proper power is not provided to SBCs.

        If you run dmesg | tail after the crash (from a command prompt), are there any error messages. Did you also update the system's packages when updating RetroPie ?

        My next step is to attempt another fresh install of retropie and to load only one game to attempt it that way.

        Not sure if that would help, unless you've added some configuration to cause this issue which might be solved with the default configs.

          Thanks for the reply.

          I'm not overclocked. I'll try the official power supply tonight. The one I'm running is a higher amp rated supply with a power switch that has treated me well, but I'll give the official supply a go to rule it out.

          I'll also run dmesg | tail and see if it shows anything after a crash.

          I can't remember if I updated system packages as well or not when updating the emulators. Is there any way to tell?

            Here's an update.

            Official Raspberry Pi power supply made no change.
            Confirmed no overclock in the /boot/config.txt file, and also ran

            watch -n 1 vcgencmd measure_clock arm

            to confirm that the clock speed wasn't exceeding the default for the pi4.

            Lastly, here are some more output log files.

            from /dev/shm/runcommand.log

            Parameters:
Executing: SDL_VIDEO_KMSDRM_CRTCID=87 SDL_VIDEO_KMSDRM_MODEID=41 /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mupen64plus-next/mupen64plus_next_libretro.so --config /opt/retropie/configs/n64/retroarch.cfg "/home/pi/RetroPie/roms/n64/Legend of Zelda, The - Ocarina of Time (U) (V1.2) [!].v64" --appendconfig /dev/shm/retroarch.cfg

/opt/retropie/supplementary/runcommand/runcommand.sh: line 1319: 1034 Segmentation fault SDL_VIDEO_KMSDRM_CRTCID=87 SDL_VIDEO_KMSDRM_MODEID=41 /opt/retropie/emulators/retroarch/bin/retroarch -L /opt/retropie/libretrocores/lr-mupen64plus-next/mupen64plus_next_libretro.so --config /opt/retropie/configs/n64/retroarch.cfg "/home/pi/RetroPie/roms/n64/Legend of Zelda, The - Ocarina of Time (U) (V1.2) [!].v64" --appendconfig /dev/shm/retroarch.cfg

            some different values for SDL_VIDEO_KMSDRM_CRTCID and ""MODEID than the prior runcommand.log file, but the same segmentation fault at line 1319.

            And now here is the results of dmesg | tail (I can provde the full dmesg if needed, but its quite long. The tail was captured immediately after a game crash)

            [ 4419.025503] usb 1-1.3: New USB device found, idVendor=045e, idProduct=028e, bcdDevice= 1.10

            Hopefully something here sheds some more light on the issue.

              Yes, it's the same line since is the emulator that's crashing, the SDL_ env variables are just for setting up the resolution.

              And now here is the results of dmesg | tail (I can provde the full dmesg if needed, but its quite long. The tail was captured immediately after a game crash)

              Yeah, nothing stands out. The last line is an error, but it's benign and wouldn't cause the crash.

              Can you get a verbose log and post it on pastebin.com ?

                  Hm, nothing new in the log from the emulator.
                  I'll check to see if there's any regression with the core, but nobody reported that recently. Did you try the standalone emulator, does it exhibit the same issue ?

                    I have the exact same error after recently updating lr-bluesmsx.

                    The error only happens on launching any msx2 game.

                    I also tested this on another pi4 setup I have and it does the same thing after updating the core.

                    I tried reinstalling and remove and install but error still happens so replaced the core with a backup I had made and works as expected.

                            Forgive my ignorance, but what is the standalone emulator?

                            When launching a game, I get the option to press a button to configure, and there are 6 options to choose from:

                            • lr-mupen64plus-next
                            • lr-mupen64plus
                            • mupen64plus-gles2n64
                            • mupen64plus-gles2rice
                            • mupen64plus-GLideN64-highres
                            • mupen64plus-GLideN64

                            Most of my playing has been with lr-mupen64plus-next, and a bit with lr-mupen64. I get crashes in both, but lr-mupen64plus-next seems to run smoother overall than lr-mupen64plus.

                            Admittedly, I haven't played much with the not libretro emulators that I can choose from, mainly because I already have a save file with the lr-mupen64 emulators that works for both. In that regard, is there a way to take a save file for the lr-mupen64plus-next emulator and convert it to work with one of the other 4 non lr emulators? that would allow me to test those out in more detail.

                              @mjs2011 lr- are the libretro (RetroArch) emulators, the ones without are the stand-alone versions.

                                I was able to convert my .srm save file from lr-mupen64plus-next to an .sra file with this online tool.

                                https://drehren.github.io/ramp64-convert-web/

                                I then copied the .sra file into /opt/retropie/configs/n64/mupen64plus/save/

                                Then I launched ocarina of time with mupen64plus-GLideN64 and played it nonstop for about 2 hours without any crashes or major issues. GLideN64 may have had a few more video glitches than lr-mupen64plus-next was having, but not a single crash for that entire period of time, and that was picking up the game where I left off playing with lr-mupen64plus-next.

                                So it seems that I don't have these crashes with standalone emulators, but do with libretro emulators.
