I saw one that sounded really cool, its called Chankast. Only problem is getting the Dreamcast bios files. Now I would never ask for help finding dreamcast bios, knowing that would be against the rules of this forum. I would also never ask you to email them to me at
elizabeth.jones@mchsi.com. So, do not worry, I won't ask. I would also say if you get this emulator it should be used for demo purposes only, and I am positive no one here on this board would ever dream of trying to play some ILLEGAL ISO they downloaded for it. So, for hypothetical purposes, this is a neat little program. If you do play games, play the ones you own. With the program you can play your games right off the CD. However, like I said before, you would need the bios and they are hard to find.
