Hi, im planning to us a ps1 dualshock pcb for a homemade sanwa arcade stick, but when i solder a wire to the pcb for the buttons i see on the pcb its a half circle for the button and the other half is the ground, i should only put the wire to the non ground half? also i only need to attach one wire to 1 ground place then daisy chain them to everybutton and stick and thats it? i dont have to place the final ground to anything else or back in a circle to the pcb again?

The hack is documented on BYOAC here:

thanks,

For the common ground just trace back the other side of the button pad.

dosu:

to me it looks like the pcb is grounded through the whole board
