In French, Spanish and Korean, these names are properly translated, while UK English, German and Italian replace the names with dummy text showing which language the file is meant for (written in English).

森のでんせつ
森のでんせつ (Mori no Densetsu) contains the text used in the Two-Player Endless Game Bossa Nova, and is stored between "Rhythm Rockets" and "Concert Listings".

ボスのちょうさメモ
ボスのちょうさメモ (Bosu no Chō-sa Memo) contains untranslated text in Rhythm Heaven Fever. It was translated in Beat the Beat: Rhythm Paradise, however. The text itself appears to be intended as instructions for Police Call, and is stored between "A Musical Term" and "Investigation Notes".
