Random Mod Chip ?'s from a Newbie

[mojo2185]

These questions are probably always asked, but i'm new so i'm going to ask anyway (so please be kind).

From my understanding... some sort of a Mod chip is needed to play CD-R based backups (i don't have a DVD-burner, yet...)

1. What is the best kind/brand/type to get?

2. How can i get it installed?

3. If i would have to install it... are there detailed instructions to install it? I hear you got to fuse wires and stuff, and i'm kinda worried about that part. I really would like to avoid screwing up my PS2.

Edit: Knowing what version/model of PS2 i have would probably be good info to know... so how do i figure this out?

Edit#2: Is there a general method that most use to make a backup? Or is it basicially "find your own method, and do what works"?

Thanks for any info!
