Sorry for the late submission, but could anybody please test this if you have the time?

Although I did add a few new enemy variants of original enemy types and two new items, I tried to stay strict to the original game. If, for example, the level palettes do not match with the appropriate enemies, whistle warp, and Triforce piece position, please let me know. Otherwise, constructive criticism is appreciated.
EDIT: Forgot to mention I used build 910 to make this.
