The area behind the boxes on Seven Island in Pokemon FireRed cannot be accessed. It was an area created for the E-Reader. However the function was taken out when the cards were not planned to be released outside of Japan.
You can't get behind it. But you can hack it with Advance Map.:)
I hope this helped
There is no 12 Island. There are 7 islands - that's why it's called the Sevii Islands.
Seven island is a place where you can train your strongest Pokemon you can only access it by showing the sailor who took you to the SS Anne the rainbow pass.
You have to catch 60 different species of pokemon then talk to prof. oak and he`ll give you the national pokedex and the rainbow pass which allow`s you to go to 4-7 islands.
