A short press of the switch when the system is running generates an interrupt to the SoC from the PMIC, causing a soft power off with a graceful system shutdown. A long hold (16 secs according to the AXP803 PMIC datasheet) forces the PMIC into a powered-off state, where it just shuts off the power to everything.
Pressing the power button when the board is off powers on the PMIC, which powers up all the devices on the board.
Ah, that would be great. I forgot about the ability to either force shutdown or "gracefully" shutdown the device. I certainly wouldn't want to abruptly cut power, shutting down properly is good. If they do the momentary contact switch, 10/10.
... :/c Huh, so... if I use the Gameboy power switch, I'll actually be forcing a hard shutdown instead of the 'graceful' soft shutdown? That sounds like it would be bad? Maybe... if I only turn it off after closing everything it would be okay..?
Ah! This is a good point. I think the Gameboy uses a hard on/off switch rather than a momentary power switch.
But we will figure out a solution to this, no worries
