A Link to the Past Glitches - Altered Credits
You must not have drawn the Master Sword.
- Complete the first three steps of Sword Degration
- Finish the other four dark dungeons and get the Golden Sword and the Silver Arrows either normally or through Reality Overlap III, but NEVER DRAW THE MASTER SWORD!
- Now go kill Ganon as normal, and view the credits.
Watch the Credits closely. If you did the Glitch right, then during the Lost Woods segment, the Woods will still be misty, like they are before drawing the Master Sword.
This also occurs when completing the game via the Fast Triforce glitch.
I believe that this works because the end sequence uses the current state of the area. So, because you never cleared the woods of mist, it stays even in the end sequence.
