how do i burn dreamcast games?

As Wayne says, there's a way, but it's a hard work.
You need to link your DC to your PC, then use a specific software to rip your GDRom, then downsample your files so that everything fits on a standard CD, then hack all BIN files to removes protections and finaly, burn your game.

People who release games know their stuff. I can't help you more if you want to rip your own original. Sorry.
