if it's a burn of a bootdisc, you will still need a modboard to read it (or sue of the swap trick...). the only difference ( i think...) is that it would let you swap in imports... essentially, a burned saturn bootdisc is almost useless, if you ask me, since it's primary purpose was to allow the playing of cdrs, and a burned bootdisc is a cdr itself, so it won't run without another workaround...
and why is this post under dreamcast? either that doesn't fit right, or i totally misunderstood the question...
