Q's about the psx2?

[The_Inquisitor]

I have a couple of q's about the psx2,

What is the new controller like, does it differ from the 1st.
Are the games that are released with the psx2 on a cd or a dvd, if on a cd can they be copied without a patch and is there any special gun for silent scope.

Thank you The_Inquisitor.
