My Dreamcast always played burned games perfectly. When they didn't work, I would use a boot disk to fix that problem.
However, for some reason I can't play burned games anymore. Every time I pop in a burned game, it says "Please insert game disc". The (burned) boot disks I have don't boot up either.
This is really weird, because official games and music CD's work just fine.
What's causing this and how can I fix this?
