error="Sorry - Raspbian/Debian Stretch (and newer) is not yet supported on the RPI"
only raspbian-jessie is currently supported.
take a second sd card and put retropie on it.
or that the one you have and wipe out the NOOBS and put retropie on it, when you don't need raspbian.
or make a new installation of the sd card and install PINN instead of NOOBS.
there is also RetroPie available to install side by side with Raspbian on the same sd card.
