Finally, I modified the recalboxrgbdual.ko driver by forcing 50 Hz. Since I have a Pi2Scart which, unlike the RGB Dual, doesn’t have a 50Hz/60Hz switch, I altered the C source code so that it always runs at 50 Hz, as if I had an RGB Dual set to 50 Hz, then I recompiled it for the version I'm using (Recalbox 9.2.2-pulsar).

It works! Of course, I have to use only PAL ROMs; otherwise, Recalbox will (rightly) switch to 60 Hz mode.

Hello @NilocRetep
Maybe the following Wiki article will help you: https://wiki.recalbox.com/en/tutorials/games/guides/gamecube-wii/use-original-wiimotes-controllers

@zing Thanks for all your help! I'll join the discord and ask around there.

@keimamoru je m'emballe un peu. J'ai réussi à lancer un jeux en fait pour l'instant (jurrasik park) et il est loin d'être stable. Le son est degueu

How about with an X86_64 build of Recalbox 8 using a good old fashioned VGA port, is there a way to rotate the screen to 90/180/270 degrees?

I searched and found some posts talking about this, although they are about old versions, the procedure should work in the latest version, but unfortunately I can't test it at the moment, can you test and give feedback about it?

First, if the intention is to rotate the screen exclusively for some games, I recommend the option of creating an configuration override file:
https://wiki.recalbox.com/en/advanced-usage/configuration-override/retroarch-overrides#screen-rotation

As it seems that this is not your intention, but rather to rotate the screen for the system and all emulators, I recommend that you first read the tutorial on configuring external screens on PCs, especially the part that talks about xrandr (which is the command you will need to test):
https://wiki.recalbox.com/en/tutorials/video/display-configuration/external-screen-configuration

In addition to the functions described in the official Recalbox documentation, the xrandr command has several other options, there is a complete list at this link:
https://www.commandlinux.com/man-page/man1/xrandr.1.html

The function you are looking for is:
xrandr --output XXXX --rotate left

In this post a user claims he did it, and explains how he did it:

But I also found another post that mentions this command:

@retrognm See if this helps:

@benzitor En fait ca tourne pas si mal chez moi, en tout cas si je change l'émulateur en FBA2X. Mais ma question porte surtout sur le mode AES, comment on peut le changer?
Je ne vois pas d'option une fois que je passe sur cet émulateur. Peut etre sur un fichier de config?

tu es sûr du reste de la config ?
je ne peux pas tester car je n'ai plus recalbox (j'ai des pbs de sons à partir de la 7.2, en attendant une hypothétique mise à jour)
je me rappelle qu'il faut avoir des options de configuration bien spécifiques pour que l'option passthrough apparaisse. par ex, la sortie doit être sur 2.0 même si le passthrough DTS par ex, te permettra derrière de décoder du 5.1
