Backup does not work

[filippos]

Just use clone cd for backing up original CD-R games.
My oppinion is clone cd version 3..... not 4.

Choose read to image and tick the 2 first boxes ( Read subchannel data from data tracks, and Read subchannel data from audio tracks)

When your image is ready then choose Write from image file and tick the box ( Don't repair subchannel)

If you can tick the above boxes you should be fine if you can't tick the above boxes then your cdr is probably not 100% fully clone cd compatible.
