XGD3 BACKUPS OVERVIEW

To end the confusion once and for all, *yes*, original XGD3 discs
have a higher linear/track density and therefore a higher physical
capacity than XGD2 and regular DVD+R DL media. As a result, XGD3 ISO
backups are larger as well.

For XGD3 backup support, c4eva has introduced in LT+ v2.0 the LT-MAX
feature, which allows for XGD3 backups to use the maximum possible
layerbreak for regular DVD+R DL media, and therefore all of the
available space (8,547,991,552 bytes) of a regular DVD+R DL disc.

Since there is still not enough space on a regular DVD+R DL disc to
hold the entire XGD3 game partition, not to mention the Layer 1
Video partition, this is not at all recommended as being "safe" for
Xbox LIVE.

XGD3 backups will still boot and play fine on LT+ v2.0 as long as the
last approximately 1.7% of the game partition does not contain any of
the actual game assets, which it usually won't because the end of the
game partition is near the inner edge of the disc, and developers
will try to keep their game data near the outer edge (middle of the
game partition) to maximize read performance.

Another necessary condition to booting and playing XGD3 backups on
regular DVD+R DL media is that the kernel or game code itself must
not perform any CIV (Content Integrity Verification) checks on any
part of this last approximately 1.7% of the game partition (or at
least it must not take any action after CIV failures). Even if there
are no actual game assets in this area, there is still pseudo-random
padding data which can be checked through CIV, and such checks can
even be added later to the game code through title updates, or to the
kernel through system updates.

Just like XGD2, XGD3 backups still require the correct dashboard
version-specific AP2.5 replay data. As they've done previously, MS
has the ability to change the DAE.bin by way of a system update,
meaning you may need to re-patch/re-burn at some point. The abgx360
application and database will be updated accordingly to support XGD3.


BEST PRACTICES AND SETTINGS

Keep in mind that this is the first of several potential disc-based
backup solutions for XGD3. As such, it's recommened that all
subsequent releases maintain the full ISO size and associated
layerbreak (2133520) in the .dvd, which will help to ensure that they
will be forward-compatible should any media manufacturers step up
with new larger-capacity discs (which will be necessary in order to
make XGD3 backups as safe as possible on Xbox LIVE).

The actual layerbreak for XGD3 ISOs is 2133520. However, when burning
XGD3 ISOs to regular DVD+R DL, ImgBurn will automatically reposition/
limit the layerbreak to 2086912 in accordance with the disc's maximum
Layer 0 data zone capacity (2,086,912 [LBA: 0 - 2086911]). The LT-MAX
feature in LT+ v2.0 will compensate for this and allow you to play
XGD3 backups with this wrong layerbreak, and therefore wrong game
partition data PSN locations.

In the case of growisofs as instructed below, in order to avoid
errors when burning XGD3 to regular DVD+R DL, you may choose to first
truncate the ISO to 8,547,991,552 bytes, and burn using a reduced
associated layerbreak of 2086912. This should give you exactly the
same end result as if you followed the instructions below for ImgBurn
on Windows.


INSTRUCTIONS FOR BURNING XGD3 BACKUPS WITH IMGBURN

We recommended that you use the latest version of ImgBurn (v2.5.5.0
at the time of writing, downloadable at
http://www.imgburn.com/index.php?act=download). Older versions may
handle this process differently and/or give a different set of
errors.

Although it is set by default in ImgBurn, please ensure that under
Tools > Settings > Write, you have "Layer Break (For DL Media)" set
to "Calculate Optimal".

Please ensure that the layerbreak is set as 2133520 in the .dvd file.
If you already have the XGD2 (or other) layerbreak value set in
ImgBurn, the .dvd of the XGD3 ISO will override that setting and use
the proper layerbreak.

As mentioned above, ImgBurn will automatically reposition/limit the
layerbreak to 2086912 when burning to regular DVD+R DL discs.

Please see the included imgburn-xgd3-errors.png image for screenshots
of the errors you'll encounter in ImgBurn and what to click on in
each dialog that pops up.

Step by Step:

1. Choose "Write image file to disc", and after loading the .dvd
file, click "Write".

2. ImgBurn will pop up a notice saying that there is not enough
space on the disc to burn the image, and asks if you would like to
continue anyway. Click "Yes".

3. Another message might pop up saying that optimal layerbreak
position exceeds L0 capacity. Click "Yes".

4. An error will then pop up noting that "Set L0 Data Zone
Capacity Failed". Click "Continue".

5. The image will begin writing to the disc.

6. Nearing the end of the write process, ImgBurn will pop up an
error at around 97% or 98% (this is what we want -- it's
intentional!). Click "Cancel".

7. A notice will then pop up asking if you would like ImgBurn to
try and perform the "'Close Track/Session/Disc' functions". Click
"Yes".

8. Let the disc finalize, and you're done!


INSTRUCTION FOR BURNING XGD3 BACKUPS WITH GROWISOFS

truncate --size=8547991552 xgd3game.iso

growisofs -use-the-force-luke=dao -use-the-force-luke=break:2086912
-dvd-compat -speed=4 -Z /dev/dvd=xgd3game.iso

en bref, le support originale des jeux XGD3 a belle et bien une partition de disc plus grand qu'un DVD+R DL vierge, du coup la taille des jeux dumpé seront aussi plus grands.

les jeux seront gravés a 98%97% et grâce a l'option LT MAX que C4eva a développé sur son FW LT+ 2.0 il seront bootable normalement. MAIS tans que le 1.7% de l’extrémité du DVD original ne contiennent pas des donné nécessaire pour le jeux (mais c'est peut probable car les développeurs évite cela pour maximiser les performance du lecteur)

... et ceci n’est qu'une des plusieurs méthode pour "l'utilisation de backup XGD3" et la team continue ces recherches

les backup dumpé avec le logiciel de la team Xkey ne seront pas valable.

layerbreak utiliser = 2133520


dsl s'il y a des erreur, ce n'est que ce que j'ai compris

Rien de bien méchant juste à changer le layerbreak et à forcer l'overburning

Génial C4eva ^^

Attention, ceci vient d'un groupe de pirates, RROD.

Et ils ont l'air de raconter pas mal de conneries qui contraste avec ce que C4eva a dit.

ah oui c'est vrais je vien de lire les coms est effectivement ceci vient de l'"NFO" d'une release pirate, ce n'est donc pas la méthode officiel (layerbrack ..etc)?, a supprimer donc
ps: mais comment ils ont pu dumpé le jeux ? puisqu'il n'existe pas de release public du fw 0800 !!

Je vais quand même faire un article, on aurait tord de ce priver d'une telle info. Je trouve que ça peut être intéressant.
