Don't assume there is automatically a hack of a game that is exactly how you want it.
There is no hack of Black/White that turns the game into Ruby/Sapphire/Emerald. There is no way to edit the overworld of the game due to the immense amount of 3D objects.
The closest to what you want would be a hack somewhere in this very subforum that turns Diamond/Pearl/Platinum into Ruby/Sapphire/Emerald. However, I don't know if it was ever finished or a patch was ever released.
Though if you can wait, there will eventually be a remake of Ruby/Sapphire made for the 3DS. Or at least it looks that way.
He's a pretty decent troll if he's made you all open his thread, read his post, comment on how bad of a troll he is, and then made you all look upset and defensive.
Yes but not as easily as just swaping. You have to install fresh copy of Windows on it, and you may be able to save some stuff from old windows on it, you will have to reinstall most
