To my understanding I meet all of the prerequisites to recieve the old sea map from prof.oak. I am champion of all regions, i have about 806 hours of playtime, i evolved 146 pokemon, i own and have dex data of all pokemon in the kanto region including the legends, i beat lance and mewtwo. But yet when i go to prof.oak he just gives me a compliment on the pokedex without giving me the old sea map. Can i get some clarification as to what is the problem?

Hi there,

 

It is not Prof. Oak who will give you the Old Sea Map but, it's an old man located on a rooftop of one of the buildings in Celadon. Quoting from this guide:

Go in Pallet Town and talk to Prof. Oak, let him take a look to your Pokedex.

 

It's now time to go to Celadon to take your Old Sea Map.

Enter in the building next to the Pokecenter and go on the Roof Top by taking the elevator.

 

 

 

 

 

If you meet the requirement, the old man will give you the Old Sea Map. Good luck!

 

Best regards,

Astreus.
