Okay I am not an expert at all so any help would be appreciated. I am on system menu 4.0 ISO 249 REV 13. I am trying to use an external USB for the first time. I created a partition on the drive and used WBFS Manager to format it to WBFS and then I used the manager to load an ISO on it. I plug in the drive and go to NeoGamma R7. However it says that Neogamma should be used with REV14 or later. It still allows me to proceed but when I try to mount the USB drive, nothing happens! Is there something I am missing? Also, what do I do to install Rev14? Thanks.
