Since two types of lockout chip were used in Europe, European NES game boxes often had an "A" or "B" letter on the front, indicating whether the game is compatible with UK/Italian/Australian consoles (A), or the rest of Europe (B).[citation needed] Rest-of-Europe games typically had text on the box stating "This game is not compatible with the Mattel or NES versions of the Nintendo Entertainment System". Similarly, UK/Italy/Australia games stated "This game is only compatible with the Mattel or NES versions of the Nintendo Entertainment System".

European "Mattel" and "NES" Versions

In the UK, Italy and Australia which share the PAL A region, two versions of the NES were released; the "Mattel Version" and "NES Version".[39] When the NES was first released in those countries, it was distributed by Mattel and Nintendo decided to use a lockout chip specific to those countries, different from the chip used in other European countries. When Nintendo took over European distribution in 1990, they produced consoles that were then labelled "NES Version", therefore the only differences between the two are the text on the front flap.


По сути получается, что Маттель или НЕС версии имеют Пал А, остальные (не знаю, как их назвать) Пал В. Чуть запутано, но получается, что для английских версий лучше собирать Пал А.
