Ok I don't know what my PS2 version is but I believe its V4 (It says SCPH-30001 and has a electric warning on the bottom).
Anyway aside from what version is my PS2 what Mod chip should I buy? I'm getting ready to order one currently and I don't want to be stuck with a piece of crap. I would like something with a good boot rate and not to hard to install of course. I'm sorry i'm asking this question but like I said I don't want to be stuck with a piece of crap.
