Hello Everyone,

I downloaded dolphin and lr-dolphin to my rpi5 yesterday using the retropie-setup script. I then added a couple roms to the gc folder, but I've just been trying to play Animal Crossing, which worked fine at first but kept crashing after playing for about 2-3 minutes on the lr-dolphin emulator, around the part where you put in your name and the name of the town. (I tried to play it multiple times, it didn't crash at a specific part, just around this timeframe.) I got frustrated and decided to quit, and I downloaded the RetroPie-Extra script from ImAQwertyGuy on Git-Hub to download duckstation and the sm64 pc port.

After doing this however, now none of my gamecube games will launch at all through lr-dolphin, using verbose-logging I found out it was a segmentation fault. I tried deleting dolphin and lr-dolphin, reinstalling both but that did nothing. I then erased them both again through the setup-script and then deleted the gc folder at /home/pi/retropie/roms, and reinstalled them again, but it still won't launch animal crossing. All of the other emulators I have installed for other systems seem to be working just fine, I just can't get lr-dolphin to launch. What should I do?

Okay, so I just started over from scratch with a fresh install of RPI os lite 64bit using the RPI Imager, and I used the manual installation instructions from the retropie website, downloaded lr-dolphin again, and it launches animal crossing. However, the crashing problem is still there, and I don't have any overclock settings so I know it isn't that.

Is it possible to change the controller settings using the standalone dolphin emulator (dolphin-gui)? That emulator seems to work just fine, I just haven't been able to locate where I can configure my controller to work with it.

Emulator crashes on the Pi5 (which is still pending support) are usually caused by the 16K page kernel used by default in RaspiOS. TL;DR: modify /boot/firmware/config.txt and add kernel=kernel8.img at the end.

If you wish to run the standalone emulator, you can modify the controller bindings by starting the GUI and using its configuratoin menus. Install the desktop, then start it and then execute /opt/retropie/emulators/dolphin/bin/dolphin-emu to get the emulator's GUI/menus.
