Changing Great Fairy Items
This is a useful set of hex addresses to know. By changing these pairs of bytes, you can change what items the Great Fairies upgrade. If you're testing out a hack, this is especially useful for being able to load in a fully completed save and then downgrade your items (for example, going from a red tunic to a blue tunic).

Original Bytes:

==Waterfall of Wishing (Near Zora's Domain)==

GIVE: 03/48D3: 0C (Boomerang)
GET: 03/48D7: 2A (Red Boomerang)

GIVE: 03/48E3: 04 (Shield 1)
GET: 03/48E7: 05 (Shield 2)

GIVE: 03/48F3: 16 (Empty Bottle)

Change the GAME OVER sound
$47532 is the location for the sound that plays when the game over text appears.

The values only go from 00-3F before looping.

The original value is 26 (hex)

Conker's High Rule Tail has this set to 33.

Uncle doesn't reactivate rain state.

In case you want Link to do escape entirely swordless but want to give him a sword later on via uncle.
At $02DF65, replace that byte and the next 5 values to EA (NOP). This will prevent Uncle from setting a checkpoint which triggers the Escape sequence (which also re-enables the rain).

The bunny palette issue

oh Nintendo, you troll
Solved the bunny palette problem.

When you construct a custom main sprite (ie Link), you will surely encounter a massive palette bug, when you draw the dark world equivalent (ie bunny) of the sprite, like seen here:

after pressing X for map, and returning:

And this is why:
at
1.) DD308, = green tunic pals for main sprite, 2 bytes for one colour, 1E bytes in hex

2.) at DD329, = same, but...

Force blue tunic before red
If your hack, like Parallel Worlds, does not force a dungeon order, and could potentially allow getting the red tunic upgrade before the blue, and you'd like to stop the player from skipping an upgrade, you can achieve this by placing blue tunics in both chests (assuming both armors are retrieved from chests, if you want to give them to the player in another manner, this may not work), and then setting the blue tunic alt treasure to red tunic. Then, no matter which one the player collects first, they will always get the blue tunic first, then red.

Parallel Worlds boomerang fix

Possible fix for the magic boomerang turning into rupees
Edit: superskuj provided a proper fix, so I'm replacing my original with his. Ignore my dirty hack below, this one works. This version makes the red boomerang chest always give the red boomerang.

Code:
PC 0x03B552: 0x46 -> 0xFF // Red boomerang alt treasure: none

Alternate version. This version puts the blue boomerang in that chest instead, but makes the red boomerang the alternate treasure for the blue boomerang. This way, if you miss the blue boomerang, you don't get the red one. Also, if you somehow...

Turn off the grey and gold colours of Link's hands when receiving Gloves
When you receive the Power glove and the Golden glove (Titan's Mitt), Link's hands turn either grey or gold. This is convenient for Alttp, but if you are using the custom Main Sprite, the grey and the gold colours will affect some other colour, which might be used for any part of the sprite, thus defecting it.

This fix will disable the additinal grey and gold colour to affect the main sprite (mandatory if your hack uses a custom main sprite):

Boots kick off speed
I was toying with Oracle of secret demo today and here's something nifty which i'm not sure if someone already found it.

You know that "startup" time which you prepare to run? you can lengthen or shorten the time via the following rom address.

$07/B29A or 0x3B29A in a unheadered rom.

1D is the default value - 01 is the minimum value which link starts running immediately. (80 is the highest value you can go)

Dark world bug fix when in collecting-pendants phase

There is a severe bug in original Alttp if you go into the dark world early (doesn't happen in original game though).

Native Alttp:
1.) If you are in the phase of collecting pendants and go into the dark world and get defeated Outside, the game will spawn you in the Light world. (Not really a bug).

2.) If you are in the phase of collecting pendants and go into the dark world and get defeated Indoors, you will start back...

Changing the number of flying floor tiles

Well, it's easy enough to change the quantity of tiles that come up.

change this to

$4BA1C: C9 XX B0 06

Where XX is between 0 and 0x16, and represents the number of tiles it forces to spawn out of the floor. This will cause the FlyingTileFactory overlord to self terminate earlier than in a vanilla rom.

Dummied out Frame control in Zelda LTTP

Author: MathOnNapkins
Take an unheadered ROM of Zelda 3 (aka LTTP)

Change $39 and $3A to 0xEAs *Original values are 80 16*.

This NOPs out a Branch Always instruction. That's it. Now load up your game in an emulator.

Press the L button to freeze the game. Music will continue running as will animations like water and flowers, but sprites and Link will be frozen on the screen.

To advance by a frame, press the R button. To unfreeze the game, simply press L again.

Final Fantasy style chests

Author: MathOnNapkins
If it ever annoyed you that Zelda 3 chests can only be opened from the front (which sort of makes sense, but regardless) there is a simple two byte change you can do to eliminate this.

Go to offset $3B576 and change that byte and the following one to EA EA.

The instruction before this looks at $2F (Link's direction) and the instruction you're NOPing out branches if it's not up ( 0 = up, and it's using BNE). The other directions are down = 2, left = 4, right = 6.

So there you have it, Chrono Trigger/ Final Fantasy style chests using only two bytes.
