The download will also include the necessary configuration files needed for Retroarch to show them.  The script will also update the required retroarch.cfg files for the emulators located in the /opt/retropie/configs directory.  These changes are necessary to show the PNG bezels with an opacity of 1.\n\nPeriodically, new bezel packs are completed and you will need to run the script updater to download the newest version to see these additional packs.\n\n**NOTE**\nThe MAME bezel back is inclusive for any roms located in the arcade/fba/mame-libretro rom folders.\n\n\nDo you want to proceed?" \
