RetroPie support for the Pi5 is still pending, so some things might not work.

but if i launch retropie i get a black screen

There's no 'retropie' application, what exactly are you launching ? Are you using the RaspiOS Lite and starting EmulationStation from the command line ?

Hi guys,
I'm not sure that writing on this "old" post is correct, but my situation is similiar (Pi5 + VGA666 + CRT) and the config.txt too (I report my all config.txt at the end).

I installed Retropie starting from RaspiOS Lite, and put emulationstation on the autostart, so when I switch on my Pi5 it starts automatically...and it works, I can see it and I can launch games. All works. Terminal, games and retropie applications views very well definited.

But I've a problem: ES' interface (the system menu, the one that appears when you press start) is blurry and quite unreadable. I tried to change theme, now I'm using pixel-tft, but it didn't got better.
I tried a lot of different config.txt configuration ("thanks" to chatgpt), but all of them caused the images to flicker, not only in ES but in terminal too. I also tried to use 480p and 480i or to specify in es_settings.xml to use a different (480x640, 800x800,1024x768) resolution...no results.

Probably would be sufficient to magnify system font or to change colors (light gray against white isn't very contrastated), but I cannot find a file for doing this. I tried modifying the .xml of the theme (pixel-tft), but I didn't reach any result.

It's really a shame, because the system works well, but this first impact gives a bad impression.

How can i get a well readable ES interface?

@DeMoN3 You should have opened a separate topic. While your setup may be similar to the original poster's setup, it's not the same problem. To answer to your question - you need to increase the resolution to get a better picture, the 240p you have won't work very well with ES.
