[quote=122451]What does the rc.locale thing do? Is that so that when I reboot it keeps that setting? I’m guessing that power setting is temporary if I run it from the command line…
I wouldn’t fiddle w/ that. It sets your locales for currency, language, time and date format, etc. That too is better set via the wizard in RetroPie.
If I were you I’d place my Pi next to my router, set the channel not to 11 (as advised by someone else) and run the blue MS-DOS like wizard. To test if it all works. Then go further from that. Good luck :)
