people think about what your doing puting a chip in your ps2 will mess it up and sony wont reply if you need your ps2 fixed if you modified it. so what am trying to say is your not allowed to modifie ur ps2 if you do install the chip and if it stops working because the chip and you ask sony to fix it they will say NO because ur not allowed to modifie it. but if u want to thats ur choice I cant stop u
