Newbie Needs Help

[xx_joe_joe_xx]

I recently started reading up on mods for the ps2. I don't know much at all about them, but would really love to get a chip installed. I have a few questions concerning this and would be appreciative of any help.

1)do i need "special" software to burn the games?
2)can i use a cd burner or do i need a dvd burner?
3)can i watched burned dvds with a chip?
4)is getting a chip (soldering) the best way to go?
5)can my laser be damaged (i have read this)?
6)how difficult are the chips to install?
7)can i play old nes games, etc. with a chip?

I know this is a lot to ask but i am very interested in getting a chip and i want to make a wise decision.

Thank you to anyone who replies!!!!
