On pull down menu pick Programming/Software - then pick Delta Update.
What I do on a PC - PNY USB stick formatted to Fat 32 nothing else on it ( don't use san disc ) download update and put it on my desktop, it appears as a zipped file. Left click it once, then right click and menu comes up, I pick extract to and go to computer - USB stick and extract all.
When done go to the game with it turned on, open coin door and plug USB stick into the USB cable by the cash box. Go to Utilities - Hit USB Update, hit enter. Screens says updating then may go black. Wait patiently, when all done the game reboots - pull out the USB stick, close coin door and you are good to go.
