Keep trying, mine did the same on .89 tried 4 different USB sticks. In the end it took.
Yesterday, same stick , .92 and worked first time .. go figure.
Good luck.
On another note, balls coming out of the orbit, they need to not hit the top of the slings , right? Causes the dreaded "boom boom ,out without blinking" down either side. Or tilt )
Quoted from Oneangrymo:Guys Im having a hard time getting a USB drive to work for update. I have a Mac, Im formatting the usb drive to ms-dos (fat32). Then I copy the files to the usb drive root like it says. The pinball machine simply doesn't notice the usb drive when I insert it. I have tried two sandisks. Any ideas?
