y0,
Right go to google and type in 'Playstation Place' follow the site to find out what version PS2 you have.
If you ps2 is a v4 I would personally sell it on eBay or local paper, and buy another ps2 and try and get a v7 (i have one for sale

) as this is the best version.
Then get a 'Matrix Infinity' modchip, as this is the best one
For xbox, you need to do some research, find out version etc. If i bought the infinity, I would get the Aldain modchip for free.
