Ok in the left pane when LB is open your SNES platform is named Super Nintendo (SNES) just like your associated platform is? Sorry to ask it sounds like you are saying it does but since I'm not sure I thought I would ask again. I'm relatively new to RA but SNES was the first system I setup using it and it worked so seamlessly that I'm surprised that there is an issue if you have everything named correctly though I'm out of ideas as to what is causing your issues. Mismatching platform names and core mistakes are usually the leading causes of RA troubles in LaunchBox.
