Hey, someone knows if is possible to open a door in mossdeep city. Is the back door of the house with a old man. ???

You can't open it without a Gameshark. Use the 'Walk Through Walls' cheat to go through it and all you'll get is a battle with a funky Unown.

Oh sounds like fun.

what do you mean by funky, what letter?

You could use a E-reader to get inside to fight the trainer
