Hi, im about to buy a Matrix Infinity fir my V4 Ps2 but I've seen many people with problems with this modchip. Is it an easy modchip to install and use? Is there a big chance of the modchip not to work or to damage your PS2 if you solder it yourself. Any tips for installing the Infinity so my Ps2 doesnt break since I have no more money left for a new Ps2. Please help.
