The game was originally going to be released on the GC alone, but when they decided to put it onto the Wii, they noticed the Wiimote was meant for you to use your right hand to swing the sword and not your left. So, since the game was just about completed with all the maps and stuff very close to completion, they mirrored the entire game to fit the Wiimote. See more...

The Legend of Zelda: Twilight Princess - 6 mistakes
Glitch: If you save while in the cannon room and load the game again, you will be unable to progress any further. The reason for this is that you cannot warp out or leave the room because it says Shad is still in the room with you. But he is not actually there, so it is impossible to ask him to leave, leaving you stuck in the room.
Glitch: This is for the Wii version of the game only. In some places, like the Goron Mines and Arbiter's Grounds, there are places where Link can fall into either lava or quicksand. If you do, a short cutscene will play showing Link sinking into the lava/sand. If you press the 'home' button just as Link's fingertips are the only things you can see, you can press the 'Reset' option on the home menu and you will appear on the version of the Bridge of Eldin map you see on the title screen. On this screen, do not press any buttons or the game will freeze. Run to the north where you will find the edge of the map. Run off, and you will get a game over. When the option to retry comes up, hit yes. The scene where King Bulblin kidnaps Colin plays. You will be trapped on the Bridge of Eldin without Epona. Jump off the edge of the bridge three times and retry. The cutscene will play again and you will get to re-play the fight with King Bulblin.
