Can Anyone Give Me Some Advice On Copying Dreamcast Games Please!

[moley]

Hiya again
Just another quick message.
Im trying to copy Dreamcast games is it true that you cant actually copy them to play on the Dreamcast.
Well so i have been told anyway
Or if you can whats the easy way to do it and what type of software do you need, I have Nero Burning Rom 5 but im not sure if you might need a seperate program to help copy them.
Any suggestions would be grateful in this Hour of Need
Again thanks in advance for any tips you might have to make life that little bit easier in the world of Copying.
Regards
Moley
