yes the wire is just shorting the controller so the cpu thinks the button has been "pressed"

anon if you have a home console like a nes or snes please take a controller apart and try inputting buttons while the system is on

heres a controller
its the same idea do you see the pads? practice on that first

anon, let it cycle\rest for 48 hours and try again
also it might not be cooked these older pcb can be v finnicky

dont give up


can you elaborate on what happened when you
'shorted' the coin input to ground?
you touched it for less than a second right? like the amount of time you would be pressing a button for mario to jump?
