From the dreamshell site, which one of these is the one I burn into the disc for my dreamcast, and which is the file I need to have at the root of the sd card?

DreamShell 4.0.0 Beta 3 / DreamShell / DC-SWAT - Сайт о Sega Dreamcast и не только.

options;
DreamShell 4.0 Beta 3 (CDI Image)
DreamShell 4.0 Beta 3 (Form SD Loader)
DreamShell on PC Loader v1.3
DreamShell 4.0 Beta 3 (Module SDK)
DreamShell 4.0 Beta 3 (Docs)


I'm guessing that the first is the cdi image for the disc, and the second is what needs to be unrar'ed and placed on the root of the sd card?
