I never had much luck with the .bat I setup additional apps for every game one to mount the disk before the emulator and another one to unmount the disc when the emulator closed basically it is doing the same thing except I put in much more work then the people using the .bat.
Mednafen Saturn Core is the future of Saturn emulation to use in LB I would suggest that any day no more needing to mount the discs RetroArch's built in controller support and the shaders I pretty much plan to never run SSF ever again.
