Pre-requisites:
truncate
growisofs, XboxBurner or OSx360
Links:
download truncate/dvd+rw-mediainfo/growisofs pack here or here
download XboxBurner here (XboxBurner bundles/installs growisofs and dvd+rw-mediainfo to the following dir: /Applications/XBoxBurner.app/Contents/MacOS)
download OSx360 here
Alternatively: Manually installing truncate:
1) Install XCode 4 from the App store (Note: this downloads the Xcode installer)
2) Run the “Install Xcode” app created in your Applications folder
3) Install Macports (download here)
4) Install the necessary binarie(s) using the following commands:
sudo /opt/local/bin/port selfupdate
sudo /opt/local/bin/port install truncate
Step 1
Truncating an XGD3 ISO on OSX:
/opt/local/bin/truncate myXGD3backup.iso 8547991552
Step 2
Burning w/ XboxBurner GUI:
This is not possible yet as the LayerBreak field is fixed. Will update if/when XboxBurner is updated to support the required offset
Burning w/ growisofs using XboxBurner binaries:
/Applications/XBoxBurner.app/Contents/MacOS/dvd+rw-mediainfo /dev/rdisk5
(use this command to verify which drive is the DVD writer)
/Applications/XBoxBurner.app/Contents/MacOS/growisofs -use-the-force-luke=dao -use-the-force-luke=break:2086912 -dvd-compat -speed=4 -Z /dev/rdisk5=myXGD3backup.iso
(repace rdisk5 with the correct drive number)
Burning w/ growisofs (using attached binaries):
dump the 3 binaries into /usr/sbin
dvd+rw-mediainfo /dev/rdisk5
growisofs -use-the-force-luke=dao -use-the-force-luke=break:2086912 -dvd-compat -speed=4 -Z /dev/rdisk5=myXGD3backup.iso
(again substitute rdisk5 with your DVD’s drive number)
Burning w/ OSx360:
In OSx360 “Configuration” uncheck everything except for “Perform Action on File Open” and set to “Go to Burn View”
Check “Specify Custom Layer Break” type 2086912 *hit return/enter* then close the configuration window
Before burning set “Speed” to 4X (or 2.4X)” and “Method” to growisofs
