Guia para grabar DVD9 para el O2!!

"...Here you have the method to create a correct copy 1:1 from you original PS2 Dual Layer Game
PTP & PS2
PTP are the abbreviations of "Parallel Track Path". This method is supported in the news game librarys for DL disc.
The disc can be treaty how an only disc of double layer (ISO information only in layer 0) or the disc can have double ISO filesystem (in both layers). In this last mode, you can see the disc similar to a double side disc.
From the PS2 console, the developers have two functions: one to know if the disc is dual layer and the LBA from the layer 1 starts and other function
to search a file in layer 0 or layer 1 (you must to specify the layer).
The first function can be used to do a dvd check or to handle a LBAS table to access to the differents files in layer 1. For this reason, it is necessary
create a exact copy (1:1) from you original disc that it respects the layer information.
Some of the competitors of O2 announce support DVD9 when in fact, they have done a patch for the GT4 game only.
I prefer not to deceive to the O2 users: I have made a real patch thinking to support this and others games! So if have done a bad backup, it cannot work under O2 patch, but if you have done a good backup (with the real layer information) it work perfectly. The other solution is to create a patch only for GT4... well if you want to create this patch, you can start now, but i must think in a generic patch and it is not possible to do without a exact copy 1:1. OK? Wink
OTP and PTP differences
OTP are the abbreviations of "Opposite Track Path". This method is used in DVD Video and for you backup under DVD+R DL. The difference betwen PTP and OTP is: in PTP the layers starts from the center of the disc and finish at the border of the disc. In OTP, the first layer start from the center of the disc and finish at the border of the disc, but the second layer is read of opposite form (border to center). So the real change for the software is the layer 1.

(extracted from DVD DECRYPTER)
Here you have the information about original GT4 game. To create a good backup, it is neccesary the coincidence of the two last lines between your backup and this original. But in addition, a compatibility problem exists.I have done some test with the aid of a friend: if you backup have DVD+R DL as booktype, it work in V4 to V7 and V11 models (V11 is a 'rare' case). In V9, V10 and PSTWO is necessary DVD-ROM book type (or you dvd backup is rejected by the DVD controller and you can can see a precious red screen Razz)
Some models of DVD DL burners put DVD-ROM book type by deffault (surely in new models). But other models need to change the book type manually.
Making the Backup
To create the backup, you need the software DVD DECRYPTER. Only with this software, you can be sure the backup work. The reason is: DVD DECRYPTER use a extra file (MDS file) to know how the info must be writed in the differents layers. With other software, you can burn the info but it can have different layer information (so a sector in layer 1 in the original, can be in layer 0 in the copy Confused)
===============================================
Reading the original disc.
1) Starts DVD DECRYPTER application. put GT4 game in the DVD burner.
2) Select in the menu Mode->ISO->Read
3) Select the source (you DVD Burner)
4) Select the destination file
5) Click in the ICON decrypt to start
When the operation finish, you have two files: ISO file and MDS file
Writing the DVD+R DL copy
1) Select in the menu Mode->ISO Write
2) Select the file MDS as source
3) Select in the menu Tools->Drive->Change Book Type. Select your appropriate driver and change the book type to DVD-ROM
if you driver is not supported it is possible put DVD-ROM by deffault.
4) Click in the icon to write (if you have a DVD+R DL of course! Very Happy)

This is the information readed from the backup:

As you can see, in the Physical information last recorded, the booktype is DVD-ROM. With this information the backup works in alls PS2 Wink
The layer information is the same, so my patch can work correctly Very Happy
About 1.61: the betatesters have the patch. i hope to release this patch in short time. This patch is not thinking in HDL support. For this support you have a patch from the ps2 scene, the right way to patch only a game.
The new patch can be considerer as one beta: to test this new support and the surprise (i hope you wild be happy with this new feature Wink )
Please, to do the backup use this method: if you use other and the disc don't work, you are the responsible..."
