I have been searching everywhere and can’t find any reliable info on adding a power button to either Picade or Raspberry Pi 3 build b. There also seems to be various schools of thought on whether or not you need to safely shut down, and considering I’m building a Picade from scratch with just the picade board and all my own other stuff, I was hoping I could get you guys to chime in on:
A) How do I wire a button to Picade or RPi3b to invoke shut down, and
B) Is this even necessary if I’m using Retropie? Any concerns with just shutting off the power strip this is plugged into?
Thanks in advance for your help!
