Hi all,
I've been thinking of having my V3 PS2 chipped as games are very expensive but theres all these chips about that do all wacky things and I just want a mod chip that will not do to much harm to my V3 PS2 and that will not involve a swap trick and thats not hard to install can anyone Help

I just need to know how much the chipa are and what they do and how hard they are to install cheers
