Reply To: Snes console using raspberry pi

Emulation Station offers an option for shutdown in the menu. That option runs the shutdown command.

I think that the approach of the power switch offered by http://mausberrycircuits.com/ is what you would like to have. There are also other sources to get the same functionality, e.g., http://www.pi-supply.com/product/pi-supply-raspberry-pi-power-switch/, http://lowpowerlab.com/atxraspi/.

I hope that helps!?
