Well i have a gameshark and used the code all key items in the beginning of the game. Now i am in slateport city. I saw a crowd and the captain. i talked to the captain and what not and then team magma stole the submarine. Team magma is still in front of the museum and i cant get them to move. I talked to the blueprint guy and he didnt give me anything probably because i already have the devon goods. I cant move on in the game until i go into the museum and team magma is in the way. Does anyone know what to do or a code to delete key items?
