Does anybody remember in (I think) FireRed and LeafGreen this old guy in a house that talked about his house being drafty? Behind him was a door way covered up by boxes. I never figured out if you could do anything with that or get into the door...Just a random question I was wondering about today.

That's pretty much nearly every PC in every house you just described.

I'm pretty sure there's something like that in Emerald's Sootopolis City too. From what I remember, I think it had something to do with using an e-reader. (Don't take my word for it though)

I did actually enable such an e-Reader feature in Lilycove City in Sapphire using the Battle-e cards. I never tried them with other games, so I am not sure, but I have heard about the houses of which you speak.

The E-Reader stuff was so unpopular they removed is from Emerald.

Funny thing is, when they first revealed Ruby and Sapphire the e-reader got revealed along side it like it was the next big thing for the franchise.

The Barcode Battler? I've seen that thing. It didn't work as well as advertised.

Fun fact: the Barcode Battler has a Super Famicom game that it can link up with.
