Proper retroarch.cfg file needed

Hi
Just unpacked my GS, assembled it, started the software and almost immediately messed up my retroarch.cfg.
Can anyone provide a fully setup retroarch.cfg, because when restoring mode and resolution (ans almost everything else) do not fit any more.
Thank you in advance

Hi
more or less solved. in the .config directory a backup of the original config file named retroarch.cfg.bak is located, solved my issue
