There are different releases of the CBS PAL games for Atari 2600 (same as for the PAL games for Colecovision): Single language and multi language.

Like for the Colecovision, the single language releases seem to be the initial releases. But to cut down costs, CBS probably switched to multilingual releases later. The single language releases probably exist in several languages – I have some in German and English, but they should exist in French, Italian and other languages too.

I have German releases of Carnival, Venture, Blueprint, Donkey Kong and Wizard Of Wor. I have an English release of Solar Fox, so I have to get the German version of that one too.

Note: When talking about "languages", I mean the language of the boxes and instruction booklets, NOT the language inside the games. The games are the same worldwide, with English text.
