check your associated platform tab for RetroArch by default LB will name the system Sega Master System so if you named it anything other than that it won't work. As for the Famicom Superfamicom they aren't by default listed in the Associated platform tab for RA so unless you have added them to the associated platform tab they won't work either. To get to the associated platform tab go to Tools select manage emulators when the new form opens double click RetroArch this will open another form from there go to the associated platform tab. add superfamicom and famicom in empty lines (assuming you already don't have entries for them).
