Do you mean it won't launch through RA or LB if LB is the issue did you go into the RA manage emulator setting and make a SG-1000 line in the associated platform tab if not you aren't passing the core along to RA when you try to load the game and it isn't working. If your issue is with RA I do have it working using the GPgx core with zipped files but they should work unzipped also
