I just recently bought a Dreamcast and got what few games that I could for it, and I have also already burnt a few games from .CDI files and they work beautifully on it. But there are a few games that I cannot get to work (House of the dead 2, Legacy of Kain: Soul Reaver, soul Calibur, ect.) and I'm stumped as to why they are not working. Do I need a specific Utopid boot disk? Or does it have to do with the files I downloaded? Any guesses or solutions? Also my Dreamcast is 1999 version (or so I believe) it has a 0 circled on the bottom of it.
