Running PS2 Games From PS3 HDD

[2JZFAN]

Ok guys with the recent release of the Playstation 2 Hard Disk Drive support and the size of this community where are we on getting PS2 games to run from the PS3 HDD?

• What do we need to do to get PS2 games to run from the HDD?
• Where are people working on such things?
• Where do these people talk about such things?

I've looked all over the net and found nothing about anyone trying anything..

I mean has anyone even tried the old MC exploit on the PS3..? I know it's far fetched but let's get some chat going on. If we discuss it maybe we can come up with something. With the lack of interesting titles currently available on the PS3 I'd love to get some PS2 ISOs on this beast.

Yes, they have already tried the typical things, but none work. They have been able to boot apps on retail discs, like SwapMagic,HD Loader, etc.
MC exploit was fixed in the slim PS2 version.
SM boots ok, but theres no metheod to swap a disc thru the slot yet.
HD Loader boots ok, but cannot find the HDD.
There is talk all over the net, but not many people have the PS3, so patience is required. Some of the brilliant coders may not even have a PS3 yet.

PARADOX is working, its only been 1 month since release it took the XBOX 360 about 4 months just to get a video up let alone get released.

Thanks for the very informative post! To me it sounds like nothing more then HDL pressing a disc that can find the PS3HDD or emulated PS2HDD on PS3 HDD..? So all they need to do is map out the HDD and where things are and HDL should work with the PS3..? Let me ask you this, how do companies like Pelican and the makers of HDL press discs? Is there any place we can buy such discs? What is the process that goes into pressing them? With gothi and his people making way on PS2 saves from the PS3 and HDL botting on PS3 it sounds like it'll happen sooner then later.

Lastly, where did you find all this information out? If need be PM me because I'd love to get involved where I can.

PARADOX released PS3 rips if I'm not mistaken.. I'm not so much worried about piracy, I'd like to run my backup PS2 discs from my PS3 HDD much like I use them on my PS2. I don't think this idea is entirely far fetched.. Further, this isn't the same situation as the 360 and in my opinion the PS3 is much more open then the 360 will ever be.

Im not sure how those people aquired the "stamps" to press the discs, but im sure Sony has taken extreme measures to ensure it dont happen too easily this time around.

as for where i found the info, a lot right here in the PS3 Forums, some at PS3News (although im not fond of them, they do spend a lot of time getting info others have to offer) , ps2hd.com and sksapps.com. Theres a few other sites i dont recall offhand, but if i come across them, ill post them. Im sure once the PS3 is more readily available, more progress will be made at a faster pace. The real question is, what is Sony up to when they post the firmware updates!

Yeah see that's one thing that has always bothered me.. I always wondered how a silver HDL disc worked in a PS2. I mean if someone gave out that info we could work on burning our own discs.. I know about the bad sectors but I believe there's ways to burn them on a disc in linux.. Similar to how people rip 360 games if we could rip the entire disc raw we could mirror it in a burn.. custom software may have to be written to access parts of the disc but in theory it would work. I just can't imagine after all these years and all these insiders NO ONE ever explained how products like GS/CB/HDL boot as pressed discs..?

What about my theory on something like HDL working with mapping of the PS3HDD? If it can boot from a pressed disc.. they could make the changes release a new disc and we'd be on our way..

[JNABK]

The info the PS2 reads to authenticate the disc is pressed into the inner ring of the disc, there is no burner capable of duplicating this. This info is stamped into the disc.

mapping for HDL, i dunno. Maybe a new app will be easier, since Sony is well aware how HDL works by now.

pressed? like region coding? can't region coding be written over in linux with the proper software? The burner can duplicate, it's the software we need written to write to the burner. I believe this software as well as a key from the official Sony discs is what allows GS/CB/HDA/HDL silvers to boot. If they created such software why isn't it out now? If there is no software what type of machine do you need to press such information into a CD? How did these companies get it?

Ok so we start a new app just like HDA/HDL which uses the PS3s file structure.. Rip some games to the HDD or send over some ISOs.. that simple? I'm surprised it hasn't been done already. I'd think the people capable would have ways to get a console..

I guess your still not getting it:
How it Works
The authentication system for the PlayStation 2 is twofold. When a disc is placed in the drive, the PlayStation 2 first checks the media type of the disc. After detecting mediatype the PS2 looks for an engraved barcode in the Burst Cutting Area (BCA) of the disc, a few centimeters from the hole in the middle of the disc. If the disc has this barcode, and the barcode matches the format of naming games (SCEx-XXXX), the disc check is finalized and the TOC of the game is loaded. If no engraving is found in the BCA, the PS2 will not boot the disc, unless it is a DVDR, and contains an encoded movie. (thus allowing home movie DVDs to be played on the PS2 as if it were a DVD player)

If you have a disc press, rather than a disc burner, you can press a game with a glass master, and give it a barcode in the BCA. The PS2 will then play the game or whatever homebrew with no problem. Like i said, i dont know how the people who have the 'stamp' or 'glass master' aquired it, but it how they press the discs to boot on a PS2.

[JNABK]

Heres the process to create the glass master and stamp:

Glass Master preparation of the 200 cm (8 inch) diameter 6mm thick glass master starts by stripping the old photo-resist from its surface (since the glass blanks can be recycled). This is followed by cleaning and final washing using de-ionized water. The blank master is then dried carefully and ready for the next stage. The surface of the clean glass master is then coated with a photo-resist layer 150 microns thick by spin coating. The uniformity of the layer is measured with an infra red laser. The photo-resist coated glass master is then baked at about 80 degrees Celcius for 30 minutes. This hardens the photo-resist layer ready for exposing by laser light.

Laser Beam Recording is where the photo-resist layer is exposed with laser light in a Class 1000 clean room-controlled environment using a blue gas laser directly from the source audio or CD-ROM data.

The photo-resist is exposed where pits are to be pressed in the final disc. The photo-resist surface is then developed to remove the photo-resist exposed by the laser and therefore create pits in the surface. These pits should extend right through the photo-resist to the glass underneath to achieve good pit geometries as specified in the Red Book. The glass itself is unaffected by this process.

The active surface (called the "father" - containing pits) of the developed glass master is then metallized either with silver by evaporation or a nickel or nickel alloy created by sputtering. The glass master is then played on a Disc Master Player (DMP) to check for any errors. Audio masters are actually listened to at this stage.

The final stage is then making the reverse image stamper or "mother". The mother is then form-pressed onto the extruded "children" membranes using high speed hydraulic presses. This membrane will ultimately contain all the binary information used to play the disc.



The finished compact disc that the customer receives is a combination of the child's membrane layer, an aluminum layer which reflects the laser light back up into the player, and a polycarbonate (plastic extrusion) outer shell. The final disc must be perfectly uniform and well balanced if the disc is to perform flawlessly.
