I have a few questions about this.......

1) I heard it was only available in Japan, is this true? Do I have to order it online or what?

2) Is it in English? If it's only available in Japan I don't imagine the commentary being in English.

3) Would I need to buy a special part for my PS2? I heard that the games sold in Japan are not compatible with my American PS2, is this true?

1) Order it online.

2) You can download a patch from the internet that translates the Japanese to English (not commentary, but Japanese commentary is better).

3) You will have to get a mod chip for your PS2 IF your PS2 is version 5 or later. I would suggest getting a professional to do it (as mine is being repaired because I don't know what I did to it). Get help from www.ps2modchips.com. The alternative if you have a V4 or lower is the knife trick. From what I know it's not that hard to do and it will allow you to play imports (and burned games ?)

How can I tell which version I have?

Knife trick is a bit dangerous!. If you get it wrong then it is the end of your PS2.
