Knowledge hole

[Xebulous]

I read on a site somewhere that it is mighty strange that Sony's little protection system has never actually been cracked. Yes there are modchips but the actual reason why a blank cannot be burnt and the PSX/PS2 read it as an original has not to my knowledge ever been explained. E.G Where the disc differs from the original. Given the time it been in existence I find the absence of an answer hard to accept.

I have some theories but first would like to ask the members of this formum their opinions/knowledge.
