Just recently I got my PS2 chipped with the Matrix v10, I have a newer model PS2 (the ones with the quiet fans) and I can't get my multi tap to work. I tried it around a mate's house and it worked fine. I also tried my Lightguns there and they were read properly too. I tried turning off my chip but the multi tap still wasn't read! Is it because my PS2 chipped? Is there any solutions anyone can offer? This is driving me nuts! It works perfectly at my mate's house and he has a really old PS2 so I can't imagine what it could be! Thanks for your time reading this.
