I haven't ever stopped using rocketlauncher, so I can give you some pointers on that sometime if you want. When I first switched over I moved all my media into the appropriate folders of launchbox (box front, back, disc, cart, etc.) and then when I imported the romsets I didn't select any media from the scrapers, and it matched pretty well. The awesome thing about launchbox is that you won't have to mess with any xml crap, you just rick click and get to the media window and from there you can manually point to any missing media from your HQ Hyperspin set that actually is in the folder, that LB just missed. Since you are running through Rocketlauncher, the only thing you will be doing by importing your romset into launchbox, is setting up all the metadata, and images and videos. It will all still run through rocketlauncher just like it does right now.
