good luck, seriously u need it.
i modded xboxes too, it's alot easier than ps2.
to mod ps2 u'll need to solder a chip's leg pins to attach the wires, the tiny ones that almost touch each other. i screwed it up first time, i accidently had a solder go between two leg pins, and to the back of the two pins, i had to scrap it off all night, tested 5 times, failed, black screen, rescraped, etc, till i got it working again (just fixed it a hour ago infact, it's now 8:40 am here).
pain ass. i cant do it anymore, dont wanna screw my ps2 up again (it's a fat v7 ps2, hard to find/get).
it's very hard, harder than xbox.
im gonna have it profesional installed.
