Are actual Dreamcast GD-ROMs copy-protected?
Yes, as a matter of fact they are. That’s why the DC warez scene came up with the CD-ROM format conversion. It bypasses all of the GD-ROM format’s built-in protection completely. Oh, by the way, three or four actual Sega developers who contacted me recently (and who are going to remain anonymous, thank you very much) have made mention of some kind of a special protection track similar to what late-generation PlayStation games use that their official Sega GD-ROM burners can’t (or won’t) duplicate – hence the need for the CD-ROM format conversion by the software pirates. Interesting!
