Cocktail mode not flipping

[lustreking]

I'm thinking about building a cocktail cabinet this winter, so I'm working on the electronic side of it now. I haven't been able to get cocktail mode working on the games that I've tried.

I'm currently running RetroPie x86 on Ubuntu 20.04.3
Version 4.7.19
Set up following instructions at: https://retropie.org.uk/docs/Debian/
roms in fba folder
Screen rotated 90degrees in Ubuntu

The process that I've used is to enter the game, hit select and X, go to options, and set the cabinet type dip switch to "cocktail". After that, I save the game overrides, and restart the rom. However, the screen still doesn't flip for player 2. I do see that when the game loads, it is loading the configuration override, and when I go back into options, it is still set for cocktail mode.

I've tried this on several games that have a cocktail mode, and haven't had luck with any of them.

Does anyone have any thoughts on what I may be doing wrong?

Thanks!

I have also the same issue. Using Pie3b+ and tried many different images, retroarch 1.7.3 and so on, there is a huge problem as the games are not flipping. I have selected flip: yes Coctail enabled in START + X (retroarch) but its not working properly.

Is there any good flip-screen images somewhere?

@retrofam I wonder if Auto-Rotate is overriding that. You might need to disable it.
