Running PS2 Games From PS3 HDD

[2JZFAN]

Some time ago some "ps2 direct boot" docs were posted. they tell exactly what trick Datel used for their discs.

SOem info here is right. the SLUS number IS in fact encoded in the protection area. that's why all pirate discs are based off of original discs, and hae the same executable file (and ften volume name)

i dot' think anyone undrstands how to "roll their own" protection code yet, but existign ones can be copie,d provided the main exe is renamed to match the previous SLUS.

Datels trick was pretty clever. they used expensive hardware to aalyse the protection area, then came up with a weak sector pattern that when fed thru a scrambler, manged ot create an approximation of the original protection area! It was not perfect, but it was close enough to pass a lto of the time. even a perect AR dsc will sometime sfail to boot and give a red screen. this is because it's not a perfect copy of protection info.

well thanks for the post, but you know i've gotta ask if you have the Datel files. if you do or anyone reading this does please PM me. The more information I can get, the more stuff I can figure out, the easier ir becomes, the closer we get to doing a run of our own silvers.

on another note does anyone know if CB v9.3 boots on the PS3? i've been waiting on a friend o bring his by but at this point i might just go pick it up.

The docs do NOT hae the files needed to make your own selfboot CDRs. they were delberately left out, to prevent mass piracy.

i didn't expect them but i'd like to give them a good read considering what we're trying to do here.

I'm not sure about the details for DVD protection (it's not BCA though; BCA barcodes are visible to the naked eye, and I don't see them on PS2 discs), but for CD (which is what almost all unlicensed PS2 discs are) the protection is nothing to do with bad sectors or barcodes. It's based on modulating a wave into the position of the track itself. The track veers back and forth from the center and the photodiode signal is fed into a special decoder that spits out a serial bitstream (this output is the so-called "SCEX" signal). A normal CD drive will just respond to the position change in the same way as it would for vibration, wobbling etc.

So it's not a question of using the right software to send the right data to the burner, because in that context the data in question doesn't even exist. There was some work toward using creative methods of damaging the disc (after it's been burned) to create interference patterns that are "close enough" to trigger the detector, but as far as I know success has been limited.

Thank you for that. I have always wondered why my Gameshark doesn't work every time I try to boot it. Sometimes I would get the red screen multiple times in a row and get so frustrated. Luckily, I haven't had to really use it since loading the mc exploit.

I think if you google for PS2_ZoneLoader_SRC+Direct-Boot_Docs.zip you will find what you want

yes it runs

BDs have 256bits algorithm... crypt... yeah we need a huge grid... we can do a small soft to crack the keys ... or wait 10 years for it... in a single high end computer....

the SCEX is the ps1 protection, not the ps2 protection.

With SCEX you don't have to copy an existign disc, you can just put the wobble groove into your master and presto, it boots. ddon't work on ps2. they improved it.

The original ps1 prot is, however completely burnproof, because atip wobble conflicts with protection wobble. SO that's why you cannot burn a selfbooting ps1 game.

What about that HDL for external HDD via USB? Has anyone tried that yet?
Seems like that would be the mostly used PS3 loader since 3.5 drives are cheaper and can hold way more.
