I have retail versions of Spriggan and Castlevania and I want to make the best quality back ups of them to play on my Turbo Duo. Most new CD burners only allow you to burn at a minimum of 16X which does not make the best quality backups. I've read other posts in this forum that suggested anywhere from 1X to 10X depending on the burner and the medium. What is the best currently made Burner for making backups for the Duo?
