ps1 pcb quick help

[dosu]

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:

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

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

Lots of info on the hack.  Probably just take some googling.
