Well its not much to tell, but most ISOs I seen where selfboot. All you have to do is burn it to the CD.
If you run into a case where its not a self bootable disk, then you will need a bootdisk (Its been free for awhile) to load it or if you don't like using a bootdisk, you need a selfboot inducer.
Be warned. Some games are not 100% full, maybe 95% to 98% because a normal dreamcast game is over 1GB. To fit on a 700MB disk, they sometimes have to cut music or what not out of the game. Luckily, most burned dreamcast games can run well without cutting little or anything out.
