U360 Joysticks Mapping, RL and Retroarch

[Drybonz]

Now that I'm using RetroArch for all my MAME-ing, I'm not quite sure how to set up auto-mapping for my U360 joysticks.  I used to use something like this Rocketlauncher add-on with standalone MAME.  Is it possible to use this or something like it as a "app" in LaunchBox?  Can someone walk me through the steps for something like this?  I would really like to be done with RocketLauncher.  It would be great if Launchbox could integrate this ahk script for U360 support, but I'm ok with using a third party solution if that's the only way possible... just need some help with the specifics.  Thanks for any help you can offer.  I appreciate it.
