RightThere Posted February 8, 2017 Share Posted February 8, 2017 When it comes to 1990s Mixed-Mode CD PC games, such as Quake or Descent, what would actually be contained in the Sub-Channel data? That's solely for audio, right? Since ImgBurn does not burn Sub-Channel data when you burn a CD, what would be missing from the newly burned CD, then? Can someone clarify that?

LIGHTNING UK! Posted February 9, 2017 Share Posted February 9, 2017 https://en.wikipedia.org/wiki/Compact_Disc_subcode Sometimes they'd make use of the subchannel area as part of copy protection. I expect Quake predates that though. ImgBurn reads and writes ISRC, MCN and CD-TEXT, so you aren't really missing anything - unless it's something 'unusual' that's stored in the R-W channels. With the exception of CD+G Karaoke discs, that's not going to be anything you'd ever see or use. Link to comment Share on other sites More sharing options...

LIGHTNING UK! Posted February 10, 2017 Share Posted February 10, 2017 That's covered by the PRE flag in the CUE file and the drive gets told about it in the 'send cue sheet' command. Link to comment Share on other sites More sharing options...
