When the G7400 series was released, new games came in a new kind of box, known as "Plus". Some of the most selled existing games were re-released with a new label (games 22 and 38), but some others with additional content: background colours -only on a G7400- (games 1, 11, 20, 34, 39, 43).
48 Backgammon was the first new game to be released only in a Plus style. The last (and rarer) game was 60 Trans American Rally.
Not all the Plus games have Plus content. Some games are the same on a G7000 and on a G7400: 22, 38, 48, 49, 50, 57 (the + symbol is not present at the cover).
Only 3 games don't work on a G7000: 56, 59, 60. These games were only compatible with a G7400.
So in total there are 21 games in Plus box, 8 old games and 13 new games:
