Here is my attempt to rewrite the guide to burning dreamcast discs from Linux.
It is an updated and enhanced version of this post:
Burning Dreamcast CDRs from Linux
Which is stolen from here:
Using mkisofs and cdrecord to Burn a Dreamcast CD-R
My plan is to break down the guide a little more and give better explanations about what is happening at each stage. This was done on an Ubuntu desktop machine running the development release of Hardy Heron on 2 March 08.
