checked-yes =>Secret GBA Shop: If you play the game on a Game Boy Advance, you can access a hidden item shop with special rings and items. Go to Horon Village in the past and find the building where the target practice game is. There are two doors in this building: the left one leads to the target game, and the right one is normally locked. If you're playing the game on a Game Boy Advanced, however, the door can be opened and leads to a special shop selling $100 rings and items.
