Than you @zing , I think it might be also something wrong with config file but when I checked .xml game list file all the paths to games image were deleted. I restored Recalbox to factory settings and I scraped all C64 games on Skraper. I have account there now and scraped games successfully (I only had to add 50 patches to screenshots for not found games) So it's good it was just matter of few hours of work. I'm making backup of each system now if anything happens again 🙂
You probably have some configuration conflict from an earlier version, I recommend that you update your gamelists (to be more agile, use external software such as Skraper or ARRM ).
In addition, in these cases it is recommended do a factory reset (option available through advanced settings since version 7.2), you will not lose any personal data, but the system will delete all customized configuration files, if there is any configuration conflicting, it will be eliminated.
Ok I found the solution I post it here if anyone needs it in the future :
It's all my bad the Names where not in lowercase, and even if the uppercase does work without external datastorage it doesn't when using an USB Storage.
so i found out my roms are not an issue it's Recalbox 7.0.1 on pi4, those roms run perfect on my pi3 recalbox 7.0.1 .. Also i took the liberty as i said to put Retropie latest on my pi4 and those same roms donkey kong, mk, they run perfectly fine..
so this sound issue is only on pi4 recalbox 7.0.1, and it happens on other systems as well even NES, i have the same issue where the sound just hisses ,skips , pops , crackles, i took a video of it and place it here on my google drive.
I am trying to set up a VPN at home. But I feel stuck. And I have to say a few. Is Openelec is a raspberry (tied with a lizard). For example, you can read the manual for manual VPN configuration (recalbox) at home. Thanks!
@Aeris You should not change the size of the "boot" and "recalbox" partitions.
You can at most shrink or enlarge the SHARE partition (but even that can cause problems if not done correctly).
I recommend reinstalling the system, and not changing the size of the first two partitions.
