The Early Master Sword Glitch

One of the biggest discoveries in Twilight Princess has been The Early Master Sword Glitch (or EMS for short), discovered by Paraxade along with the help of Kazooie's jump strike trick.

Soon after it's discovery, two major dead-ends were found.

1. The Sumo Wrestling fight is broken when the Master Sword is obtained too early. Fighting the Elder Goron and winning allows you to enter the Goron Mines. Since you can't fight, you can't enter the Goron Mines, and if you can't enter the Goron Mines you can't get the Bow or purchase bombs from Barnes. Without the bow, you can't beat the game.
   
2. Despite not having a bomb bag, it's possible to enter Laranyu Province by either doing a "horse wedge" maneuver, or by CD-Streaming. And with the Master Sword, it's possible to play through the game normally up to the Second King Bublin Fight. Without a bow, King Bublin is invincible here, and that means no Zora Armor. But there might be a way to avoid that fight. Through Action Replay, it was discovered that if Link was to fall into a void BEFORE the fight, the fight would be skipped, and the 2 gate keys would be obtained

These dead-end can be avoided with the Early Master Sword Fix
