Technical Reason Why Copys Will Not Work w/o Mod

[Trek2344]

Hi all,

I am curious as to what the technical reasons are behind why a copy of a PS2 game will not work with out a mod chip. What types of protection are being used? And why are copys not capable of booting with out the mod in detail?

Thanks!
