Ok, this is not about pirating games or movies or music, this is about how a DVD is actually copied (the technology behind it).
What makes a copied DVD a copied DVD? whats missing from an \'original\' disc thats been mastered by the record label/studio/games house?
Like, why if you put a copied DVD game into a PS2, it doesn\'t work? What is missing exactly? How does the machine know its not \'original\'?

did you eat paint chips as a kid?

Good question actually,
I never thought of it. My guess would be the ps2 have some sort of built in code to prevent people playing copy dvd instead of the original. How does this code tell if a disc is a copy instead if it\'s original?
My guess would be disc were burned using laser that write into the dye of the disc while original disc is press...how can a ps2 tell?
even i don\'t understand what i am saying, so i gotta run.

All ps2 originals are on silver discs, copies are on purple discs. The bios in the machine will be programmed to read only the silver ones. That is where the m0dchips come in...... :sconf:

I thought they burned errors into the disc that your computer can\'t burn. Then the PS2 looks for these errors. At least that\'s how they use to do it.

Kurt Angle,
How about blue disc CD-ROM ps2 and black disc PSone?
-
Yes, there is specific coding implemented in the PS2 discs. It recognizes PSone discs as well, but the original PSone could play burned games without a mod chip, because it was unable to recognize the coding [crappy technology]. It just read discs as discs. At least that\'s what I experienced when my friend played a burned game on my PSone.
-
So why can\'t coders just crack the code and create a program/writer, to copy the disc and the code?
Im not endorsing pirating, im simply interested as to how it works. What if someone got a hold of a real DVD presser, like the ones used by studios etc?
-
they already do...geez.

bzzzzt. Ps1 still needed a mod chip. It didn\'t play pirated games unless u used a rainbow adapter or it was modded.
Racer, they already have, and burners that help hardware wise too.

Im still confused, so why can\'t big underground pirating studios reproduce a PS2 game (for example) that can be played on an unchipped console as if it was an original?
If SONY puts special code on an original disc, why can\'t pirates who use similar hardware?
-
Whos to say they can\'t. But current computer hardware will not reproduce 1:1 ratio copies on certain games, and because blanks use a dye rather then being stamped/molded like originals. They never will.
-
I guess Soulgrind must have modded his psOne and ps2 and been playing lots of pirated games....
or shall i say, this guy speaks from experience....
J/K...
-
ps1 was modded (for imports) ps2 is not.
-
Yeah...that\'s all I use it for...imported games and backups. There\'s just too many great games, can\'t let them go to waste ;)
-
^^^
LOL. Sure.;)
-
Swap discs and I believe many cheat discs are infact unlicensed products. The discs need to be pressed, it isn\'t a matter of dyes and such, there\'s information pressed (code and errors) that cd burners can\'t write. There\'s, in the case of some DVD players, ways that the laser intensity is adjusted and/or firmware coded that makes physically reading +/-R media impossible. But that\'s not really relevant to PS2.
-
interesting,
even though i am not sure what you really said...perhabs a little too technical for me...

It’s a good thing some stuff hasn’t changed around here…
As for the discs, yes they use a distorted code in some cases but most it’s a simple code that only that particular hardware recognizes. There are plenty of forms of software out there that enable anybody to crack the codes and pirate copies of the software.
