MORE GAMECODE AVAILABLE AT STERN for the PRO model.Original was 1.25 which was replaced by 1.4, but version 1.5 added today for PRO model.
Check the STERN site again for LE and PREMIUM models guys.
Note - easiest way to check for the gamecode version, is to look firstly at the "Read Me" file which shows the software version. Then, if its a higher number then your current version, then go to the download file and ofcouse copy.
