What do I need to play back-up using Jap PS2?

[xclr8]

I need help!

I am not sure what I need to do in order to play backup games. I've been looking for some info about this, but most of what I found were only related to US PS2. I heard that there's a way to play all CD-R and DVD-R without using any modchip at all, using AR2 or DVD Region X, and a knife swap trick (which I already learned how to do ). Any comment is greatly appreciated. Thank you.

By the way, my PS2 is the Jap one, SCPH 10000.
