I hate the idea of merging systems from different regions. Each system should be treated separate with their own metadata and images. Lumping the PC Engine, PC Engine CD, TG-16, TG-CD and SuperGrafx is a complete nightmare when sorting the game titles and calling back to Emumovies for correct videos. I can assure you that is going to put a lot of people off and keep them away from LB because you are limiting the database. The only way around this is importing your rom folders separate, let it pull down all the meta data from the lumped TurboGrafx 16 or sometimes TurboGrafx-16 folder (it likes to split sometimes) and then going to platform management and rename it to the correct system and do it all again. I have been able to make separate library for all my NEC systems this way and it you prioritize Emumovies over the images it will pull mostly correct data. Now the Nintendo systems are a whole other beast but I wont get into that.
