hey guys, I'm new to the DIY arcade life. i built a full size cabinet with my son. It came with a i-pac 2 controller and i purchased a Pandora Gbox-ex2 thinking i can just plug the usb into it and all will work. Well it doesn't. has anyone tried this that can give me pointers. Its already wired with the i-pac 2, i can copy the files from the Pandora just don't know where to go from there. Thanks in advance.
