The Legend Of Zelda I on NES (Mini) - Prologue of Quest 1

The introduction sets the scene for the game. Note that Ganon (Ganondorf) was spelled "Gannon" at the time. Here is the transcription of the introduction and my translation.

Many years ago prince Darkness "Gannon" stole one of the Triforce with power. Princess Zelda had one of the Triforce with wisdom. She divided it into "8" units to hide it from "Ganon" before she was captured. Go Find the "8" units "Link" to save her.
