So I just wired power button up and downloaded the picade software. The power button works great to turn on the system but no matter how long I hold the button down, there is no response.
I would assume this is due to a problem with the monitoring part of the picade software?
I am running a Pi2 powered by a 3.7v 6600 battery and a powerboost 1000c.
I have power running into the picade hat, not the pi.
I am running the newest Retropie image install with 4.9 kernel.
