Australia and Europe use PAL
America uses NTSC
Japan uses NTSC only in Japanese
In each different zone, the Playstations are made differently. Playstations made in Australia and Europe are made to play only PAL games. American playstation are made to play only NTSC games. And Japanese playstations are made to play only japanese NTSC games. So you can't play a NTSC game on a European playstion.
But, if you have a mod chip installed in your Playstation, which are now illegal it will allow you to play any version of the game on your playstation as well as burned copies of the game.
