Guys, help me out here. How can I copy a multisession dreamcast game!!! I try to copy it. It prompts me a message saying that this is a multisession disk. I don't know what to do. Help me out here. Also, I got the iso, it is under .cdi format. What do I need to do next? Thank You

You need a mastering software that's capable of handling multi-session operation. Like, Nero, CloneCD, DiskJuggler(recommended). The .cdi files are DiskJuggler formats. Let me give you a useful link for informations.
