> NES and Famicom cartridges
They are Game Paks and cassettes, respectively. Of course it's obvious what the author is referring to, but I really enjoy seeing the term “cassette” used for something that doesn't contain magnetic tape, so please pardon my pedantry :)
Peep the Famicom system manual where the cartridge connector is straight-up labeled in English as 「CASSETTE CONNECTOR」with katakana furigana (カセット / kasetto): https://ia601903.us.archive.org/17/items/Family_Computer_198...
