      I'm at my wit's end here, hope someone can point me in the right direction.

      Running retropie on a pi 4, all games (including NES) worked when originally set up a few months ago. Games for non-NES systems continue to work, but none of the NES games will load with any of the multiple emulators installed (all crash back to emulationstation without loading).

      I have verified that the ROMs have headers, and have fully updated all packages and have reinstalled the NES emulators.

      Below is a verbose log of a launch using the lr-mess emulator. All emulators give a variety of segmentation fault in the last line. Is there anything to do other than replacing the SD card and fully rebuilding everything?

        any particular reason you're using lr-mess for NES games? why not use the default dedicated NES emulators? they almost certainly give a better experience.

        as to your segfault, i imagine lr-mess's NES support (if it works - it's an experimental libretro core not typically used for this) it probably expects NES roms from the ~current MAME romset, in a specific format, and zipped. see this reddit post for more info: https://www.reddit.com/r/MAME/comments/d0abh5/what_format_of_roms_does_mame_expect_for_nessnes/ez8f945/ - you probably can't throw random nes roms at it like you can often do for most of the dedicated emulators.

          I was just using this as an example; all emulators give similar seg fault errors. Some of the default emulators also give a "Romset is unknown" error, but that doesn't seem to be an issue on other systems and I have verified that these have headers. Below is the log for lr-fbneo-nes

            @0sabotagecopper lr-fbneo is another romset-based emulator that needs roms from a specific romset version, and likely in .zip format - even NES games.

            indulge me and get a log of these nes games on the default NES emulator for pi4 - lr-fceumm

                this doesn't seem standard. perhaps you've got an invalid video mode set via https://retropie.org.uk/docs/Runcommand/ ? you can clear it via going into runcommand when launching a NES game and remove any changes from default for the system.

                or are you running via the desktop? if so, this configuration is not supported.

                i'm not super familiar with the kms stuff ( @mitu may know!), but in the meantime please provide all the info requested in https://retropie.org.uk/forum/topic/3/read-this-first so we get an idea about anything non-standard on your system.

                  Changing the resolution didn't do the trick, I ended up restarting with a fresh RetroPie install, and everything is working again.

                  Thanks for the tries to help, something must have gotten corrupted or configured at some point, not sure what that would be, as I changed very little.

                    NES emulation in MAME is not great, and that's a bit of an understatement, so i would really recommend to avoid it.
