If you have an import version of the PS2, for example if you are in USA and you have bought a Japanese PS2, then you will encounter several compatibility problems. In fact, every console is produced to work just in a precise area of the world. In other words, a Japanese PS2 will work only with Japanese DVD movies and Japanese games; an American PS2 will play only american DVDs and American games. Anyhow, there are several mod chips available which make your PS2 able to play games and movies coming from every part of the world. Use of modchips to play games imported from other countries is not illegal. < I google that...
