How to get MSU1 games to work in Launchbox

I'm looking for some tips and tricks to get MSU1 games to work in launchbox. I've enjoyed playing them on my Emulation Station (retropie) and had not problem importing them to the Retropie. I can't get the MSU1 games to play, I zipped them up and have used several SNES cores.

Thanks

When you say "zipped them up", are you putting the entire folder contents into an archive? ROM, MSU file and PCM files? Individual MSU1 games should be in their own folders, the ROM should be okay to be zipped, but the MSU file and PCM files shouldn't be.
