I leave my picade in the office and it seems to be nearly a daily occurrence that someone remaps the buttons in a way that makes it impossible to exit an emulator.
Luckily it turned out to be a 5 minutes job to add a power button once I finally decided it was worth doing. In retrospect, I should have done it months ago. I thought I’d share it now so the next guy (or gal) doesn’t waste months putting it off. :)
I ordered one of these buttons, which fit nicely.
And stole the python script from this guy.
