Zelda 1 and 2 on the NES are 2 of the toughest games ive ever played, heres a new rom hack released:

The Zelda II Rev edition hack updates the graphics for Zelda II for the NES. Almost every enemy, boss, item and character in the game has received a minor or major changes. The over world tiles & palettes have also been tweaked.
Many enemies and a few items now resemble the first Zelda game better. This includes Zoras, Wizards, wise men and more. Other enemies such as Gooma, bots, Megmats & wosus now look closer to the instruction manual artwork. A full list of changes is in the readme file.
