Nah it is 190: aside from how Morimoto actually said it was 190, look at what happens after that; the actual Pokémon that show up are junk data and the Pokémon they represent are the early Johto Dex in order. It's like the game automatically just fills in with the Johto dex. Also the beta sketches, all released around the same time, kinda prove it too.
Remember this isn't a hypothesis, Morimoto confirmed it for me! I did stress 190 when I talked to him, and since 190 is seemingly a random number that's probably why he reacted so strongly.
