Most of the SONY 1st party games have that integrated into the software ... but the 3rd party releases don't.

Even if you want to play PS2 games online games on a PS3 you'll need that network setup disc to create an online profile on a virtual PS2 memory card!
You can just download the necessary software on PSN for free now actually, no need for the disc.
