Is it possble to make a copy of a copy?
 

If so, what am I doing wrong?
I´ve tried making a copy of Virtual Tennis selfboot, the burning reports no errors or other comments (using diskjuggler 3.0). When #####ing the diskcontent it´s no longer the same.

Are my settings wrong, is it not possible just to copy?

Do I have to remake the files to .iso or .cue?

Please help!!

Using DiscJuggler, I have copied a couple of my self-boot conversions that weren't originally selfbooting. Maybe it's in your default settings.

Try these:

MODE-2, Blocks=2336, CD-XA

(I'm almost certain of the 2336, I know it's 2x36, but I'm not sure of the second digit. It will be in the drop-down menu after you choose Mode-2.)
