Thanks, @Einherjar. Yes, this is an issue, but there's not a lot we can do about it, outside of guesswork. There's no way to identify a game between LaunchBox and Retro Achievements other than via the name of the game. So if we can't identify a match by guessing, then we're basically out of luck. The only other option would be to allow you to manually match them up, which may be a possibility going forward.
