Hi Guys,

I was a bit reluctant to propose this workaround as I haven’t tested it thoroughly but given the increasing number of posts about it here we go!

Launch a command line and issue the following command:

 $ sudo chown -R pi:pi /opt/retropie/

You should end up with:

$ ls -la /opt/retropie/
total 24
drwxr-xr-x  6 pi   pi   4096 Jul  1 22:40 .
drwxr-xr-x  5 root root 4096 Jul  1 21:34 ..
drwxr-xr-x 17 pi   pi   4096 Jul  1 21:47 configs
drwxr-xr-x 13 pi   pi   4096 Jul  1 21:42 emulatorcores
drwxr-xr-x 24 pi   pi   4096 Jul  1 22:30 emulators
drwxr-xr-x  5 pi   pi   4096 Jul  1 22:31 supplementary

Let me know if this does improve your situation.
cheers,
