Revision as of 21:40, 16 January 2014

In time this page will hold information about records, races, and strategies. We've also got records and races. See also the menu above for pages on specific topics.

Differences between versions

General differences between versions are available at The Cutting Room Floor. Here are some speedrun-specific notes:

The version most run, with the highest level of competition, is the US NES version. It's the absolute fastest version for any category. The US Virtual Console version is speedrun-wise the same, except that you lose a second every 10 minutes due to the slightly-lower VC NES Framerate (~60.002 vs ~60.099).

The possible advantage of the Japanese FDS version - faster attack leveling - is mitigated by slower elevators, the addition of load times, the inability to pick up items as a fairy, the harder Dark Link AI, the inability to get 'scroll lock' in Glitch Town (you turn into a fairy instead), and the lower gem XP payoffs. The Japanese Virtual Console version about evens out with the original FDS hardware, due to faster load times, balanced by the lower framerate.

The PAL version is most like the US version, only with slower movement on the overworld, and the inability to fairy through doors.

Game Mechanics and Glitches

Experience and Leveling

If you do not level properly in this game, it gets harder, and harder, and the game quickly gets out of hand. Make sure to have Attack level 4 by the time you leave Palace 1. This requires some luck, and some practice. Know your 6 counts. Know your P bags. It's critical to learn how to manipulate your experience, to ensure the biggest possible payoffs at the end of each palace. Level Attack early, and make sure your "Next" level is Attack every time you put a gem into a statue at the end of a palace.

Know the experience chart, and know what monsters are left to kill in each palace (maps to come here soon)

Drops and 6 Counts

There are three kinds of enemies in this game: Enemies with no drops, enemies in the "small" group, and enemies in the "large" group. This is important to know, because when the enemies drop items is not random. Every sixth enemy you kill in a group will drop an item. Kills in one group to not affect kills in the other group. So, if you kill 5 Bots, then an Iron Knuckle, killing another bot after will cause a small drop. Likewise, killing 4 Iron Knuckles, then killing some Bots, then killing two Stalfos will cause a large drop on the second Stalfos. The kind of drop you get, however, is random. Small drops will usually be a blue jar, but have a 1/8 chance of being a 50-point P Bag. Large drops are equally likely to be a red jar or a 200-point P Bag. This means if you kill the same enemies, in the same order, every time you play the game, you will get drops at the same times. This is an important fact in routing the game, as well as in recovering from bad luck or mistakes.

Fairying through Doors

In the JP FDS and US NES versions, if you have no keys, and are in fairy form, you can go through a door without using a key.

If you have a key, a key will be used, even if you're in fairy form.

However note that in the JP FDS version, you can't pick up an item in fairy form, so in that version this isn't useful for doors guarding items, such as the glove, the raft, the boots, and the flute.

Luck Manipulation

Combat Techniques

The most important thing to know is to keep your momentum. If you're moving forward, you can keep hitting enemies, instead of letting them hit you while staying alive. This means that generally, the worst possible attack to make is the standing sword attack. It's slow because of the backswing, and you stop to make the attack. Better is the crouching sword attack. It's faster than the standing attack, but it also kills your momentum. However certain enemies are bad to crouch stab, such as the ever-annoying Tin Suits, who have top-heavy hit boxes. Jumping is the key to combat in Zelda 2. Often a jumping crouch thrust is best. Sometimes you will want to jump, crouch, and then thrust on your way down from your jump. Against other enemies, or for a final attack, you may want to attack while you're coming up in your jump. Enemies like Iron Knuckles need special techniques. Jump at them, do not crouch, and then thrust on the way down to hit them in the visor. However in a two square-high corridor, there isn’t room to jump. Instead, when facing an orange or red Iron Knuckle in this situation, press A then B right after, very quickly, to get attacks in. A blue Iron Knuckle can defeat this. Instead do jumping crouch stabs (most notable at the last key in palace 5).

The Jackhammer

The downstab is a powerful attack. While the game limits the frequency of sword stabs that are possible by pressing B, it does not limit the number of stabs possible by pressing down to do a downstab. This means that getting on top of an enemy and mashing down will get in many hits quickly. The Jackhammer is possibly most notable against Iron Knuckles in three tile high corridors (often seen it front of items). By jumping into the iron knuckle and doing a downstab, it's possible to get *inside* the enemy doing a downstab. By mashing down, one can hit the enemy over and over, killing the Iron Knuckle (or getting through it with a lot of damage done at least) without doing any damage at all to Link. Other useful jackhammer opportunities: Dragon heads, Bubbles (in a casual run or a no-reset run where 50xp is needed), Barba, (in theory) Boss Gooma, Horsehead, Helmethead (after the helmets are removed).

The Whirlwind and the Panicked Dolphin

Related to the jackhammer is the whirlwind. Primarily used in TASes, the whirlwind does aerial crouch stabs, while alternating pressing left and right. Similarly to how mashing down will create multiple hits, so too will constantly changing directions. It's rare that this is doable and practical in a live run, but there is one enemy whom it is useful to attack in this way, or at least try: Thunderbird. Sometimes, you'll just get lucky by mashing around like a panicked dolphin.

Encounters

Spawns

There are two types of overworld encounter spawns that can happen. One spawn is based on steps, one on time.

The overworld random encounter timer always counts down, even in a side scrolling area. When it reaches 0, enemies spawn. If you are on a path, it stays at 0 until you step on terrain that can spawn enemies.

The timer resets to 8 ticks upon exiting a side scrolling area. If you are standing on the overworld when it reaches 0, it resets to a new number of ticks. The number of ticks is based on what terrain you are standing on when the time encounter is spawned.

Grass, Swamp 32 Ticks
Desert, Forest 24 Ticks
Graveyard 9 Ticks
Lava 3 Ticks

When a tick counts down is based on a global timer, usually every tick takes 21 frames. However, the first tick will be variable. It could be 1 through 21. Only where you are standing when the counter is set from 0 affects the time. Moving to a new terrain has no effect once the timer is already counting.

Link moves at about 1 tile every 16 frames, so this works out to be between 10 and 11 steps (~2.8 seconds) before you can expect an encounter when coming out of a side scrolling area. This will always be the first type of spawn you see.

Overworld step counter for random encounters counts up from 1 to 255, increasing by 16 each step. When it rolls over 255 it resets to 1 and monsters spawn. This means every 16 steps there will be an encounter spawn. Terrain does not affect steps-- the path also counts as a step, so if the 16th step is on a path, no encounter will spawn for that cycle. Resets to 1 upon exiting a side scrolling area.

In northwest Hyrule, the area around north palace and palace 1, the step counter isn't active and as such you can never get a step encounter there.

Movement

One fourth of the time, overworld monsters will perform a random walk in any direction. The rest of the time, overworld encounters will try to home in on you Their movements follow this pattern, depending on the monster's position relative to link:

Consequences of this include:

If a monster is far away from you, up in one of the random walk quadrants, there's a good chance it'll never get near you.

If a monster is moving horizontally just above or just below you, it will only break out of that pattern by a random walk.

Valley of Death Red Jar

The jar at the beginning of the Valley of Death is known for despawning. SDA user fiskbit examined the situation. It turns out there's a glitch, where a memory location ($071F) that remembers whether the red jar has been taken, is overwritten by other things in the game.

Long story short, if you attempt the encounter skip at the start of the Valley of Death but fail, you have to scroll the screen to the right, before leaving the screen back to the left to try again. If you don't, you risk despawning the jar.

It's also possible to re-spawn the jar using the same glitch, but it's probably not useful in a speed run.

Beginning Advice

Run the 100% All Keys category. It's the best introduction to the game.

All Keys Route

A true beginner to the game may not even know where to go or, worse, will emulate the routes used by the very best players playing the hardest game categories. This is a mistake. My advice is to follow this route:

Magic Container south of North Palace
Town of Rauru – Shield Spell
Heart Container south of Palace 1
Palace 1: Parapa – Candle
Trophy
Town of Ruto – Jump Spell
1-up south of Medicine
Bagu
Town of Saria – Life Spell
Death Mountain – Hammer
Magic Container west of Hammer
1-up southwest of Mido
Heart Container east of Palace 2
Medicine
Town of Mido – Fairy Spell, Downward Thrust
Palace 2: Midoro – Handy Glove
Palace 3: Island – Raft
Town of Nabooru – Fire Spell
1-up west of Maze Island
Magic Container on Maze Island
Palace 4: Maze – Boots
Lost Child
Town of Darunia – Reflect Spell, Upward Thrust
Palace 4: Complete
Heart Container north of Palace 5
Palace 5: Ocean – Flute
1-up north of the Valley of Death
Town of New Kasuto – Magic Container, Spell Spell, Magic Key
Heart Container east of Palace 6
Palace 6: Hidden – Cross
Town of Kasuto – Thunder Spell
Palace 7: Great

This is a basic route that, if executed well enough, would produce respectable times in the 100% All Keys category, assuming the runner does not fairy through doors.

Maps

If you don't know where these places are, or how to get through the dungeons, there are maps to help. Mike's RPG Center has great maps, though a beginner may find the palace maps of NESMaps.com easier to read. An intermediate form based on Mike's with extra details added is here, with Great Palace map here. A diagram showing some of the ways that do not result in encounters from the beginning is here. Here's a little animation that could serve as a reminder of the route. I link it because it's cute: Only after mastering this route should the runner attempt more advanced routes, such as those run by the top any% runners, which include skipping the candle entirely, getting the Fairy spell before Palace 1, and skipping spells like Life or Spell.

Sample Leveling Plans

7/8/8

This was the leveling made known by John 'Pro_JN' Nurminen. It's relatively easy to pick up, and used to set world records in the past. This is a very beginner-friendly strategy. The only tricky part is making sure to get enough P-bags (or do Trophy Cave before Palace 1) in order to get Attack 4 from the Palace 1 gem.

At Palace 1 Gem: 3/1/1
After Palace 1: 4/1/1
At Hammer: 4/2/3
At Palace 2 Gem: 5/3/3
After Palace 2: 6/3/3
At Palace 3 Gem: 6/3/4
After Palace 3: 7/3/4
After Palace 4: 7/3/7
At Palace 5 Gem: 7/3/8
After Palace 5: 7/7/8
After Palace 6: 7/8/8

8/8/7

Here is a more advanced leveling plan, used by some other record-setting runners. Credit to Feasel for walking me through it:

At Palace 1 Gem: 3/1/1
After Palace 1: 4/1/1
At Hammer: 4/2/3
At Palace 2 Gem: 5/3/3
After Palace 2: 6/3/3
At Palace 3 Gem: 6/3/4
After Palace 3: 7/3/4
At Palace 4 Gem: 7/4/4
After Palace 4: 8/4/4
At Palace 5 Gem: 8/4/5
After Palace 5: 8/6/7
After Palace 6: 8/7/7
Entering Palace 7: 8/8/7

Note that to use this leveling, you must make sure to trigger the full 9000 XP rewards at Palace 5 and at Palace 6.

8/8/7 with 3/1/1 after Palace 1

Here's a variant of the 8/8/7 leveling, which addresses the possibility of not getting 4/1/1 out of Palace 1. Credit to Duxcub, Solairflaire, and Pro_JN in helping me get it nailed down:

At Palace 1 Gem: 2/1/1
After Palace 1: 3/1/1
At Hammer: 4/1/2
At Palace 2 Gem: 5/1/2
After Palace 2: 6/1/2
At Palace 3 Gem: 6/2/4
After Palace 3: 7/2/4
At Palace 4 Gem: 7/4/4
After Palace 4: 8/4/4
At Palace 5 Gem: 8/4/5
After Palace 5: 8/6/7
After Palace 6: 8/7/7
At Great Palace: 8/8/7

8/8/6

And here is a variant at 8/8/6, used by Error72 when he set the All Keys record:

At Palace 1 Gem: 3/1/1
After Palace 1: 4/1/1
At Palace 2 Gem: 5/2/3
After Palace 2: 6/2/3
At Palace 3 Gem: 6/2/4
After Palace 3: 7/2/4
At Palace 4 Gem: 7/3/4
After Palace 4: 8/3/4
After Palace 5: 8/6/6
After Palace 6: 8/7/6
At Great Palace: 8/8/6
