u cant open it dumb huh
You can't. You need to hack it.
You will need an e-Battle card that has been scanned into an E-reader. This will allow you to get past the door in Mossdeep.
How do you unlock the door in the old man's house who lives on mossdeep city on Pokemon Ruby
not
A player needs the e-reader with a trainer card to unlock the door in Mossdeep city. This was a feature put into the game but since the e-reader was not very well taken to in the US and Europe most have never unlocked the door.
with your foot
The thibg is, you need a cheating game system, or a game shark. If you do, you might be able to get in the door. When you are in, talk to the mirror of yourself. It will probably glich up, but just remember, this is a flaw of the Japanese makings. Hope that helped!
what door?! open seasame
You can open a key lock on a door knob, or you can open a deadbolt lock on the door itself.
If the door is not closed and the draft is going out the window, then yes. An open window can indeed make a door open.
well, go to mossdeep city and talk to the guy out side Stevens door and he will ask you if you want it
well after you go through the encounter in mossdeep he is still in mossdeep in a house to the north western part of mossdeep
