I’m attempting to edit the /boot/config.txt to change my video settings, but get an error that the file is read only. If I attempt to cat or tail the file, it returns a I/O error. If I try to chmod the file, it appears successful, but doesn’t change the file attributes. I tried to open it on my laptop, under BSD, but the file isn’t even visible – even as SU.
I’ve notice that if I add roms to certain systems, the ES menu has problems. It will go black (with only the CANCEL option visible) or with others, the highlighted graphic (the large version when a particular emulator is selected) will be missing.
Doing some research, I decided to set the HDMI entry to 720p. The problem is, I can’t edit the file for the reasons listed above. I even tried to go back to my oldest backup. The problem exists all the way back to the initial installation.
Am I missing something? Permissions on the directory or something else?
