american consoles use NTSC format ours are PAL, if your tv isnt capable of displaying both, black an white pictures.

NTSC and PAL are the two main Television formats that are used all over the world. If your game console is not the same format as your TV, or the game you buy is different from the console format, then in most cases your games will not work properly (or at all).

A television screen is made up of hundreds of tiny dots or pixels which give off colored light when contacted with a beam of electrons. This beam is fired by an electric gun from the back of your TV which sweeps across the lines of pixels row by row extremely quickly. Because PAL and SECAM systems use an extra one hundred lines, it offers increased picture quality. However the NTSC scans the picture at a faster rate due to the American electricity supply being regulated at 60Hz rather than 50Hz but this has little effect on the picture quality. What does make a difference is when games are developed using the NTSC system. This affects the PAL and SECAM performance due to line difference and scanning frequency.

NTSC

The first color television set developed in the United States after the war. NTSC stands for National Television Systems Committee and uses 525 lines and a 60Hz field frequency. This means that an electronic gun fires a beam at the back of the screen illuminating phosphor dots one at a time. To create a clear picture all 525 lines are updated 60 times in one second.

PAL

Developed in Britain and West Germany during the 1950's. PAL stands for Phase Alternation by Line and uses 625 lines and a 50Hz field frequency. This means that an electronic gun fires a beam at the back of the screen illuminating phosphor dots one at a time. To create a clear picture all 625 lines are updated at a slightly slower rate of 50 times in one second
