Exploring Oak's lab either before you step in the tall grass or just before you pick your starter when Oak asks you to reveals the two Pokedexes he hands you and green aren't mechanical devices like the anime, artwork, and later games present them to be - they're literally a pair of notebooks (and their sprite is that of a physical book, see pic related in the upper left), and the dialogue you get when you click them states that they're 'some kind of encyclopedia - but (it's) completely blank!'. Oak hands these two blank physical books to you and Green after you fight and asks you to fill them out. Since these things aren't machines that auto-update like later games and media establish, but are instead physical paper books in RGBY, then the only way they're getting filled is if Red and Green are the ones writing in them; we can assume Oak later compiles them into a formal scientific journal in digital format after he rates both characters' dexes.
