Emulator - Video Mode Help!

Hey - new to RetroArch/Emulation station. In my snes emulator settings, it won’t let me change any of the settings.

It started with the video mode, i wanted to see what CEA-2 option looked like (not good) but it now won’t let me change out of that option (even if i select remove video mode.

Was doing some more testing an selected default emulator as 2005 for snes, then true the 2010 version for this rom… and now that’s stuck too!

When I try to save/change those settings, a message at the bottom of the screen flickers that says 'couldn’t open temporary file /opt/retropie/configs/all/sedAUDieS: Permission Denied

Any help GREATLY appreciated!

Unfortunately, I don’t know anything about EmulationStation or RetroPie. If no one else chimes in here, you might have better luck on the RetroPie forums.
