It is not possible to break the boxes in Seven Island on Pokemon LeafGreen. The room behind the boxes is a feature that was removed from the game that involved the use of the E-Reader. It was removed due to the cards needed to use with the E-Reader were never going to be released outside of Japan.
you can get to blain in seafoam islands next to cinnabar island where you meet green/blue and if you talk to hom he says you have to beat blain
from the bottom of cinnabar, follow the bottom line of rocks to the right (surfing) till you see the island w/ the picknicker (green hat). go inside for gym.
