Ah, found it:
sudo chown pi:pi /opt/retropie/libretrocores/lr-viceDid that for the main and subfolder and managed to replace the crappy broken new files with the working old ones. All fixed. Thanks for the reply :)
I see how you have done it otherwise you would not be able to replace the files.
If you don't mind you can leave it that way.
However, notice that these folders normally have root user rights.
In principle you should turn them back to root.
