Galway and everyone...please help me again...

Thank you Galway, for your courtesy last time...and now I have some other questions regarding the dreamcast...
I own some Original DC games and now I want to make some backup copies of them...but how do you do that? Will progs such as CDRWIn works (dumping the image)? But if it works, how do I make it self-bootable? Or how do I use it with the Utopia Bootdisk? I am a bit annoying, sorry cuz I am still a newbie...thanks a lot, please help me again, anyone who can give me some advice plz do so
