Seems to me that even with the HDMI port disconnected, the Pi thinks that a composite display is connected.
Sorry, but I have no idea how you can convince the OS that you're using a DSI display and whether that will work without X11/Wayland on the buster. I noticed in the RPI docs that there's a KMS type overlay for the display which would make it work without X11/Wayland (as required by RetroPie), but I'm not sure whether that would work without installing the lateste RaspiOS (which is based on Debian 12 bookworm).
@gare You can get RetroArch to run in verbose mode by choosing to launch with verbose logging. Seems like an issue with the audio - perhaps PulseAudio/Pipewire gets stuck ? Does it happen also with standalone emulators (i.e. Mupen64plus or PPSSPP) ?
... understand that the forum doesnt't support 3rd party images. Only please, have you a suggest that I can try, on one precompiled image, to try to found and correct the problem?
I think the meaning of the do not support 3rd party images is still unclear to you.
This topic is closed - if you have questions or problems with the RetroPie official image feel free to open another topic, detailing the issues there.
Get a verbose log from running an emulator and then post the resulting log file on pastebin.com. Also post your joystick configuration profile here in the topic, surrounded by code tags (``` before and after the contents)
There are still a few more things to configure, such as getting RetroPie's shortcuts to work in Dolphin, but at least the games start!
If you are referring to the Hotkeys, you would have to be running lr-dolphin for that to work. The standalone emulator does have the ability to configure hotkeys, but you will need to do it through the dolphin settings menu.
You need to edit the launch command in your emulators.cfg at /opt/retropie/configs/gc/emulators.cfg and/or /opt/retropie/configs/wii/emulators.cfg. Replace the command (or add a new one) to use your installed binary instead of /opt/retropie/emulators/dolphin/bin/dolphin-emu
