Update RetroPie
The following instructions will update the RetroPie Setup script and Package Update.

On RaspberryPi:

• In RetroPie Menu, use DPad to scroll up & down, highlight 'RETROPIE SETUP' and press 'A' button.
• Press 'X' button at the notice screen.
• Use Dpad, highlight 'Update all installed packages' and press 'X' button.
• Use DPad, highlight 'Yes' and press 'X' button.
• Press 'X' button to acknowledge RetroPie-Script update.
• Press 'X' button at the notice screen.
• Use DPad, highlight 'Yes' and press 'X' button to update underlying OS Packages.
• Wait for updates to complete...
• Press 'X' to acknowledge packages have been updated.
• Use DPad, highlight 'Perform reboot' and press 'X' button.
• Use DPad, highlight 'Yes' and press 'X' button to confirm reboot. 

Note : The frist thing I noticed is the 'RetroPie' menu header now displays 'CONFIGURATION' instead of the misleading 13 GAMES AVAILABLE message.

FIX : DragonRise Inc. Generic USB Controller Issue - After RetroPie Update
Following the RetroPie update the controller stopped working when navigating up & down using the DPad.The controller name and the DPad up & down values have changed.

On RaspberryPi:
