ps2 games on ps3 help

My nephews got an 80gb ps3 and we're trying to play their ps2 games on it. They play just fine, but the graphics look awful. There are jaggies everywhere.

Do I have to adjust the settings for the system to make them look like normal? Or is this it?

Some games will play better than others with the 80gig's software emulation.

You can set your preferences in the System menu, or you can press the Home button while you're playing a PS2 game and select "Options", "Other Options", and that will allow you to turn "Smoothing" on and set the screen to 4:3 or Stretch.
