Do you need to chip ps2 ?

[penz]

I really just want to play back ups not too bothered about imports ...main thing is the warrenty cause it's still got another year and after having several sony products break down on me i would like the option of being able to take the thing back .....guess i'm gonna have to wait a while eh ? before i can play back ups or at least until warrenty runs out....do you still have to access the main board for the external mod chip devices ? or is there anything like gameshark etc .....used to be able to do straight copies with clone for ps1 and use external mod ....no more eh ? thanks for taking the time to answer though..
