technically this is kinda a warez topic heh, but i'll post one last time...
Installing a mod chip is not that hard...takes about 25 minutes if that...little longer if you are unfamiliar with soldering...all you do is connect the pins on the chip to the included wiring..then solder the wires to the pins on the motherboard...you don't even have to physically solder the chip to the mobo you can just tape it up inside the case as I did...
providing the person you buy it from includes the diagram that comes with the chip it's a big color poster and it's hard to mess up

besides playstations are like what 30 bucks nowadays heheh
