How can I modify a DVD image (ISO) and then burn a new DVD?
I know of two techniques to modify readonly disk images - using either a sparse image or a shadow file. Here is what to do using a shadow file:
Create an image of your cdr (which you have already done)- I will call this xxx.cdr.
Use hdiutil attach xxx.cdr -shadow
which mounts the read-only xxx.cdr
image along with a shadow file where all changes will kept. So it behaves like a mounted read/write image.
Make your changes.
Unmount the disk - you will now have xxx.cdr and xxx.cdr.shadow
Now run:
hdiutil convert -format UDTO -o newxxx.cdr xxx.cdr -shadow
Then burn the newxxx.cdr
to `DVD-R.
This is the method I have used to create a Snow Leopard image for use by Parallels or VMware. My posting in a MacRumors Thread is just part of a long discussion.
You may need to vary the above to suit your particular needs - I have no direct experience of working with PS2 images.
