newbie help

I have a couple of questions:
1. Do i need a modchip to play the games, or cn I use a boot cd like i use for my dreamcast?
2. do you copy ps2 games the sameway you copy psx games (like using cdrwin and diskjuggler)
3. will my backup psx games run on my ps2?

thanks

1.yes you need some sort of mod chip no its not like the d/c where you can just put in a disc
2.yes just copy like ps1 aslong as they are not dvd games (silver bottom games are dvd games)
3.yes as long as ps2 is chipped
