Thanks kamyk2000 for he reply. I manage to get Yabause to launch the launch box, here is what I did.
I downloaded and install DAEMON Tools. I then clicked on "Add DT Virtual Drive" under the "actions" tab.
In Yabause, Under file, settings, General, CD-ROM, I made sure the "ISO-File Virtual Drive" was selected, and that the line below led to my Roms folder. Also towards the bottom of the General tab I click the "Autostart" box.
After that I started up Launch Box and selected a Sega Saturn game, it loaded up and was very playable.
