I finally have a computer in my arcade machine that will run Launchbox! I'm upgrading my MAME roms from 0.85 to the latest release. In the past, I have had all of the extras and snaps to support my MAME installation. I see that extras and snaps are still available, but Launchbox has its own database from which to pull information.
I have seen the Lightspeed tool on the forums, which seems like it will use the snaps and extras, but it sounds like it's currently broken. I also see a tool called CopyMAMEExtras that might be useful. For MAME, is there a reason to use the extras and snaps over the Launchbox database? Can I use the extras and snaps directly in Launchbox?
