Newbie here! Help with copying all games!

Hey! I have Nero and need help to copy all sorts of games. PSX, PS2, PC etc... Do you know a good website that gives you step by step instructions for Nero Burning Rom. I need to know what settings to use when copying a game. Also, I am unsure about inserting cracks into the games so that they work. Can you tell me what extracting the crack means and how you do it using Nero.

Pleeeeeez help!!!!
Nuff appreciated!
