We reported a few times about a green Fire FR-27 from the Wide Screen series.
Last time in March 2012 (open article in new Window/Tab).

Usually, the case of a Fire FR-27 is blue, but in very few cases it's green. It's still not clear why the case is green. Conceivable would be a manufacturing fault or that it has to do with the plastic pellets used at that time. However, this would not match the quality management of Nintendo. They would have noticed such errors and hardly brought the games to the market. Maybe Nintendo has deliberately changed to green.

The game shown here comes from a shop located in the Netherlands just across the border to Belgium. Therefore the game might come from Belgium originally and that's why one of the instruction is in French. The green Fire from March 2012 (see link above) had a manual in German. It's unclear if the different instructions were shipped from the beginning with the Games or if they were added later by collectors.
