Can I use power button to shutdown?

Just build my new picade, its great!

Now can I use the console power button to safely shutdown the pi directly from retropie?

Or is that just for powering it on?

Do I still need to shut down via the start button menu?

Thanks.

There is no need to use the start button menu, the power button safely shuts down the Picade.

Are you sure? Tried the power button a couple of times to shut it down and the system did a file system checking when booting again in both occasions.

Yes I am pretty sure, when I hit the power button it closes Emulation Station stops all the services and then powers down just like if I would use the shutdown -h command from the command line.

Powered it down 50 times at least and never had the system do a file check after rebooting.
