The "Super Mario 3D All-Stars (Switch, EN)" version is mainly in English, but according to Nintendo's official information, the Super Mario 64 and Super Mario Sunshine games are available in French with English voices in the compilation. However, the "EN" version generally indicates that the packaging and the game text are in English, so the availability of French depends on the configuration of the console and the game. It is advisable to check the language configuration on the console to access the available language options.
