in island 7, when you take the ship,
when you go into the island the first
building is a house with an old lady inside
n to the back there are boxes
blocking what seems to be an exit?
is there something there?
can i go in there somehow

and

what happens if you catch all 28 unowns
(i cant find the ! and ?) T_T
i tried in the chambers they were supposed to be in
but i only see As or Zs
=/ pls help

There may be something behind the boxes, if you use an E-Reader; I know there have been similar discussion about similar spots. But, unless you have an E-Reader, you're completely out of luck, even if there is something there.
And nothing happens if you catch all 28 Unowns. Other than that you get a special feeling, for having found them all.
Keep looking, they're all where they're supposed to be, although some of them are very hard to find.

whats an e-reader?
where can i get it?

Nintendo was supporting e-cards - to get extra content for games - but they had so little support in America that I think they are no longer available here.

LOL
i don't think i can ever get it
i'm in australia
and nothing reli happens here
=/
o well ty anyways

I know you can get an e-reader on amazon.com. I've looked it up but I don't even really know how to use it, but I really need those pokemon in altering cave. it's really cheap too, only $2.00 used plus S&H

yeah, i think im gonna purchase myself 1

WOW only $2?
but you dont know how to use it?
and anyways
all the pokemon in Altering cave, you can get in
emerald safari zone

hm.....
is e-reader what i use to
get lugia and ho-oh too?

Um no, that would be an action replay. And that would give you a non-legit legendary, which is baaaaaadddddd....
