So you Europeans want to play all of your US Nintendo games on your PAL Nintendo system, no problem, the Magic Key is here. Some company (I don't know who) released the Magic Key several years ago. This was for all of those European people. This adapter works sourta like a Game Genie, you plug the US game into the adapter and you stick the whole works into your Nintendo. According to the box, this adapter lets you play hundreds of US Nintendo games, though I really don't know for sure. Another company released an adapter named Game Key, I wonder which of these two adapters work better? It also seems as if Game Key and Magic Key were copied, the names anyway. If any UK gamer uses one of these, let me know if it works well.
