Quelque Information Sur La Gravure Des Jeux Gdx3 Et Du Layer Breack

[hyndrid]

Bonjours a tous j\'ai trouver un FICHIER NFO qui viendrais d\'une release de GOW3 3 ripper avec le nouveau firmware 0800 VOICI LE CONTENUE DU NFO sa parle du layer breack et autres:

c\'est en anglais désoler

p.s:ne me demander pas le lien de la release ou le nom de cette release cest interdit sur le forum

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

The P2P XGD3 ISO rips that were floating around before this point are

for ODDEs and are not compatible as-is with LT+ v2.0. Their PFI, DMI

and SS sectors are in the wrong PSN (Physical Sector Number)

locations and they are missing the critical AP2.5 replay sector and

SS replay table. If you intend to play XGD3 backups on a firmware-

flashed 360, it\'s up to you to make sure you\'re using proper ISOs

made with 0800 v3.0, and to double-check by running them through

abgx360 before burning.

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!
