All PS3s are backward compatible with PS2 software.

This method involves injecting a game into a single game emulator. It's how the Wii "emulated" the GameCube. Or how the PSP does it. If a game is similar enough you can inject a game and it'll run. They don't include it stand alone cause of the testing required. Plus extra cash.

As walsufnir said, this is nothing like the Wii, it's exactly the same as the PSP though emulating PS1 games (which was opened up for hacked PSPs to run basically any PS1 game perfectly).

 

Pure software emulation using NO hardware of the original console, the Wii had Gamecube hardware in it (same CPU overclocked) and basically the same GPU overclocked with same CPU code instruction sets.

The PS2 has a completely different instructions set to the PS3 for it's CPU.

The difference in technical achievement is akin to comparing a drawing by a 2 year old and the Mona Lisa ;) Same analogy goes for BC PS3 console.

Whoever are the people involed in creating the emulator for the PS2 classics have some skills that are unmatched, to accomplish this on hardware only 1 generation ahead of the emulated console, is a feat never accomplished before.

Exactly, this is a great piece of software, I think. MS did also a good job emulating the xbox with 360 but ps2 had a very complicated architecture but somehow they could do a lot of stuff by using the spes, obviously!
