PS2 backup on PS2 using modchip!!!! - yes I know this has been asked

[mjf]

Okay....here goes. If possible can someone answer all the following questions.
Becasue there is not much information on the subject here goes.

I want to try creating backups of PS2 games on the US version of the console.
I am going to use a mod chip. For example - What exactly do I need to do to create a backup of of Tekken?

Do all games need to be patched? - All the patches listed say they are for the swap trick, but we won't be doing the swap trick now that we have a mod chip.

Help please...I'd really appreciate it
