Chris Houlihan won one of Nintendo's contests. One of his prizes was getting his name in this game. The area that talks about him is a hidden area that isn't easy to find. In fact, there isn't a way to find Chris 100% of the time. To find him, save your game in the Light World, then press Reset. Start the game from the Sanctuary. Dash all the way to the bush that Link had to lift at the beginning of the game to enter the Hyrule Palace. When Link reaches the bush, Dash down the hole without Lifting the bush. If Link is fast enough, Link will appear in Chris Houlihan's room.
The "curse" actually allows Link to only use half as much magic as before (which is a good thing).
Go to the Desert in the Light World. There is a cave under a rock next to the middle-aged man. Move the rock, enter the cave, lift the pots and leave. When you leave, the Rupees in the cave will reset. Here are the basic locations of chests which contain 300 Rupees:
Light World: South of Link's House.
Light World: In the Sanctuary (via the Graveyard).
Dark World: In the Village of Outcasts. Search the top-right house.
Dark World: In the Village of Outcasts. Search the Chicken Coop.
Dark World: South of the Bomb Shop.
There are three possible solutions:
Laser Turrets, which are statues that shoot lasers, cannot be defeated. If Link is stuck in a room with a Laser Turret, Link will need to move a block to open any closed doors.
Link probably left it with the Smithy brothers. Enter Kakariko Village after giving the Sword to the brothers for them to have time to forge a new one. For that time, Link will be without a sword.
Go to the Gossip Shop (Smithy's house in the Dark World) to find a treasure chest. In the Light World, take the chest to the man in the desert to get a Bottle.
If Link tries to use the Magic Mirror in the Light World Dark World Dark World and he gets sent back to the Dark World, move to a different location. The game will prevent Link from teleporting into a bush, rock, building, etc, and then getting stuck.
Aim an Arrow to one side of the Goriya, then move the opposite direction so that the Goriya moves into the path of the Arrow.
It represents the number of times Link was defeated during your quest.
