Thank you for playing!
Regarding Professor Oak, I’ve changed the mission so many times that I don’t remember right now which one it is, but I’d say it’s this one:
- Go to the bike shop in Cerulean City with 1 million $, and you’ll be given an herb.
- Take the herb to a neighbor in Viridian City, in exchange, she’ll give you the key to an elevator.
- For the elevator, return to Cianwood City and go to Cliff Edge Gate, to the room where there’s a lake and stones. In that room, there’s a hidden button symmetrically placed to one of the missing rocks. Press it and a new room will open. Use the elevator key and read the journal.
- After reading the journal, go to Pallet Town and talk to Professor Oak.
The numbers in the letters of the Lunar/Solar Sanctuarycorrespond to the Pokédex numbers of the Pokémon you hear.
For regis, use the Braille alphabet!
