How to play ps2 games on an 80gb ps3.?

May be...

I recently bought a PS3 and learned that I had to update it to play my PS2 games. So I updated it to version 2.80 ands it still would not play. The game I tested was the original kingdom hearts. I am not sure if I downloaded the wrong thing or if the game is just not compatible. Please tell me what I need to do to get it to work.

The newer 80 gig ps3 models have Limited backward capability if you want to be able to play your ps2 games you'd have to get the 06 and 07 versions which are the 20 gig and the 60 gig

only the 06 and 07 models of ps3 are backwards compatibility, 20gb 60gb and some 80gb's. Only way is to buy one off ebay, gamestop, amazon etc. "used"
