From Jason (LB Dev)
I haven't tested this out yet as I'm already all set up and not sure I want to tinker with it, haha. But this is good news for anyone who wants to use LB with RocketLauncher.
Keep in mind that I've actually simplified this even further now. If you remove your Rocket Launcher emulator in LaunchBox, and then add a new one to replace it, you'll see that Rocket Launcher is now in the list with the latest beta. Selecting it will automatically populate all the right settings (saving you from having to manually add the path to LaunchBox, etc.).
