Nintendo Power's Zelda Strategy Guide

The Nintendo Power strategy book for Legend of Zelda is okay for completing the first quest.  It doesn't tell you exactly how to get the heart pieces or magic sword, but you don't need it.  It didn't tell me I had to burn the bush along the row of trees to find Dungeon 8.  The map is a little misleading.  It makes it look like the tree is alone in the middle of the woods.
You need to buy meat at E-5 for one of the dungeons, but they don't tell you that.  A moblin will block your path and go "Grumble grumble" until you give him the meat from one of the shops.
They also don't tell you that you need a red power bracelet to move rocks, they just tell you "move the rocks".  I wasted a lot of time on that one.  
The guide tells you you have to defeat all the enemies around a specific stairwell to go in, but it's not just that one.  Every secret area in a dungeon requires you to destroy all enemies in that room before the secret passage will open up.  
It says you can defeat the bunnies with the flute, but I've never been able to make it work.
If you stop time while Digdogger is big, you can never defeat him.  You have to play the flute first.  So cheating there doesn't help.
I don't know why they say you can defeat Pols with a flute.  It doesn't do anything.
Gannon is the only thing your stop time Gameshark cheat cannot protect you from.  Watch your health, keep hitting the dark area with the sword until he becomes visible and shoot him with silver arrows.
Second quest:
Here is where the strategy guide breaks down.  I guess they didn't expect you to get that far or something, so they slopped through it.
First of all, the yellow circle on the map that says "push tombstones" is pretty much the same color as "blow the whistle."  Gold.  That means I spent about twenty minutes trying to push open a grave to get to Dungeon 6.  A lot of other websites don't explain what you have to do, they even suggested you needed twelve hearts and a power bracelet to move the grave.  Nope, you need a friggin' flute.
The hungry Moblin in Dungeon 3 came as a surprise, but I was able to find a shop with meat a short distance away.  
The instructions about pushing blocks for Room 7 is a little confusing.  You don't have to defeat the grabbing hands to open the secret passage, though it might help you save hearts.  Try pushing all the blocks on that vertical column.  
When the guide says you can pick up a key with a boomerang, it's a damn lie.  I tried it.
"Don't go downstairs link" item 20 on Dungeon 7:  I pushed a block to open a staircase, and on the other side, I became trapped in a room with those tumbleweed skull things.  The doors would not open.  The only way out was back the way I came.  I think the tumbleweed things are invincible.  I have no clue how to get past that area.
Dungeon 7-23:  I thought the stopping time cheat prevented the door from opening, but really you just have to push a block after killing Manhandla.
Dungeon 8:  The green "use candles" icon looks just like the aqua blue "use bombs" icon.  The guide says some of the blocks you can push at this or that angle, but in actuality, I ended up pushing one sideways into another block.
When it comes to Wallmaster rooms, stopping time can screw you up, because you have to defeat all of them to push the blocks to access the next room.  Make sure they're visible before stopping the clock.
If time is stopped, no flute usage will make the eye vulnerable on the boss.
In Dungeon 9, there's a room with a T shaped platform in the middle of the lava.  The map is wrong.  There's no left door.
