Thanks for the suggestion Jason. Although renaming my platforms does get me the sort that I'm looking for in BigBox, outside of renaming the emulator platform associations, it looks like I also have to rename each platform video and re-associate each of the media types for each platform with its original folder. Maybe I'm missing a step somewhere or there's an easier way to do this? I also noticed that I ended up losing my platform metadata after closing and reopening Launchbox.
