Hi there excuzee, welcome to the Absolute Playstation Network.

You basically have 2 options...

Buy a PS2 from the region you want to play games - USA/JAPAN (they are really cheap these days and you can get a used one for little more than the cost of a new game).

Get your PS2 modified to play these games - we dont cover the how and where on this site, but there is lots of information on the internet about this.
