Double Dragon II: The Revenge (NES)
Game Mechanics - Hit Points, Attack Values, Misc. Data - Version 1.11

*I. Introduction*

This is a guide to hit points, attack values, and other relevant game 
mechanics information for Double Dragon 2 - The Revenge on the NES. All values 
are in eighths, because this is how the game divides hit-points - 1/8 of an HP 
is the smallest unit used. Where whole hit points are concerned, I use whole 
numbers or mixed fractions as needed. Values are listed from lowest to highest 
unless otherwise noted. Subjects within categories are organized by order of

*II. Notation*

Hit patterns: Some attacks, instead of hitting for consistent damage, hit for 
varying amounts of damage in a repeating pattern. In this case, I describe the 
pattern with #-#-#-#. Each number is in eighths, not a whole number - I left 
off the "/8" to make it easier to read. In all other cases, eighths and whole 
hit points are clearly delineated.

Some attacks have particular effects, which are notated thus:
(kd) - knocks down the target in one hit.
(shortfly) - sends the target a distance of one quarter of the screen.
(longfly) - sends the target across approximately half the screen.
(flyup) - sends the target mostly upwards.
(diagonal) - this move/attack can be used diagonally across the screen.

Any shortfly/longfly attack automatically causes knockdown, so (kd) is not 
used. See V. Gameplay, F: 2 1/2 D for more info on (diagonal).

*III. Player Character*

(Billy/Jimmy Lee)

8 HP (all difficulties)

A. Standard Attacks

Knee stun.............2/8
Knockdown kick........3/8 (kd)
Knockdown uppercut....3/8 (flyup)
Jump kick.............4/8 (kd)
Cyclone Kick..........1 HP (shortfly)
Hyper uppercut........1 2/8 (flyup)
Flying knee...........1 7/8 (longfly)

* This can vary based on Extra Tough enemy status. See V. Gameplay, A: Hit 
Counter/Extra Tough for more info.

The Knee Stun can only be used while your opponent is getting up. It stuns in 
1 hit.

The Cyclone Kick allows you to hang in the air for a short time, which can be 
useful for some platforming sections and for avoiding attacks.

The Flying Knee shifts your position to the side faster than getting up and 
walking. This can be used strategically in platforming sections, or for 
outmaneuvering enemies.

B. Shopping Cart

In addition, the player can use the hair grab/shopping cart technique on a 
stunned enemy. This allows you to hold the enemy and deliver a combination of 
up to 3 hits.

Possible shopping cart attacks -

Knee bash.............3-2-3-2
Throw.................6/8 (shortfly)
High Kick.............7/8 (flyup)

Up to three knees/elbows may be used, while throws and high kicks finish the 
hold. The damage varies depending on the combination. It requires 3 hits 
and/or a finishing attack to complete the hold, unless it is interrupted by a 
third party attack. Damage values add up exactly, the whole is equal to the 
sum of its parts.
Here are all possible combinations:

If interrupted

1 knee................3/8
1 elbow...............3/8
2 knees...............5/8
2 elbows..............6/8

Normal Situation

1 throw...............6/8
1 high kick...........7/8
3 knees...............1 HP
1 elbow/2 knees.......1 HP
2 elbows/1 knee.......1 1/8
3 elbows..............1 1/8
1 knee/1 throw........1 1/8
1 elbow/1 throw.......1 1/8
1 knee/highkick.......1 2/8
1 elbow/highkick......1 2/8
knee/knee/throw.......1 3/8
knee/elbow/throw......1 4/8
elbow/elbow/throw.....1 4/8
knee/knee/highkick....1 4/8
knee/elbow/highkick...1 5/8
elbow/elbow/highkick..1 5/8

Most enemies are vulnerable to the shopping cart, exceptions are noted. 
Enemies with 2 1/8 HP or more will break the hold, knocking you down without 

If the shopping cart is interrupted, the enemy will be knocked down.

C. Weapons

Some enemies carry weapons, some of which can be picked up and used by the 
player. Damage that can be done with weapons by the player is described below. 
Enemy use of weapons is described in their relative sections, since weapons 
are only used by their respective enemy carriers.

All weapons cause knockdown.

Pipe (swung)..........2/8
Throwing knife........5/8
Grenade...............1 HP (shortfly)
Morning star..........1 2/8
Incendiary............1 2/8 (shortfly)
Pipe (thrown, far)....1 2/8 
Pipe (thrown, close)..3 3/8* (shortfly)

*At point blank range, the pipe can travel through the target and hit another.

It is important to note that while you are holding a weapon, your attacks are 
limited. Other than using the weapon, you may only jump, jump kick, and kick. 
In the case of the pipe, you cannot kick (the pipe is thrown instead).

*IV. Enemies*

There are many enemies throughout the course of the game. They are divided 
into standard enemies, strong enemies and bosses. Standard enemies are grunts 
who use weapons. Strong enemies are distinguished by their extra tough status, 
fast attack rate, and non-use of weapons. A boss is any enemy that appears as 
the boss of a level with accompanying music, even if they are used as regular 
enemies elsewhere.

Each enemy category describes their HP and attack values. HP is given for each 
level they appear in, as it often varies. Where the HP of an enemy type varies 
within the level, this is notated in order of appearance.

There are three different difficulty levels - Practice, Warrior, and Supreme 
Master. The Hit Points vary between them, although the attack values remain 
the same. The HP values for all difficulty settings are given for enemies 
where applicable. Practice has only the first 3 levels, Warrior has 8, and 
Supreme Master has 9, so not all enemies are present in easier difficulties. 
The enemy attack rate increases incrementally with difficulty - see V. 
Gameplay, C: Attack Rate for more information. There are also minor 
differences in the levels themselves based on difficulty, see VI. 
Environmental Hazards.

There is a universal difference of 3/8 in enemy HP between warrior and master. 
(The only exception is in level 5, see X. Notes: 3 for more info). The enemy 
HP difference between Warrior and Practice ranges from 2/8 to 6/8.

Strong enemies and most bosses are Extra Tough, while standard enemies are 
not. Extra Tough enemies have a doubled hit-counter, but are more vulnerable 
to punches. More information on this is under V. Gameplay, A: Hit 
Counter/Extra Tough.

Standard enemies use weapons, while strong enemies and most bosses do not.

same damage pattern if used consecutively. The straight-leg kick is faster and 
is not used in combination. The roundhouse kick is slower, and can be used up 
to 4 times in a row in combination. 1 kick will stun you; but in a roundhouse 
combo, the slower attack speed means that they come in right after the stun 
window and won't knock you down.

Combo punch (4).......2 HP* (kd)
Flying spinning fist..3 3/8** (shortfly)

*Each punch in the 4 punch combo does 4/8 damage.

**The flying spinning fist, his strongest attack, is typically used as a 
counter-attack to your cyclones or hyper knees, especially if they miss.

During the first half of the fight, he can turn invisible periodically. This 
can be interrupted by attacking him during the fade-out. After losing just 
over half his health (8 1/8 damage), the screen will change from the illusion 
to a temple. His attacks and patterns remain the same, but he will not be able 
to turn invisible.

*V. Gameplay*

A. Hit Counter/Extra Tough

All characters have a hit-counter which determines when they are stunned. 
Standard enemies are stunned by 1 kick or 3 punches, while Extra Tough enemies 
are stunned by 2 kicks or 6 punches. However, the mechanics are slightly more 
complicated. To be specific, you need one hit on the extra tough enemy hit 
counter to stun them with a kick; or 5 hits on the hit-counter to stun them 
with a punch. For standard enemies, it requires no hits to stun them with a 
kick, and 2 hits to stun them with a punch.

The hit-counter is reset for all characters after being knocked down, or after 
approximately 3 seconds without hits.

While extra tough enemies have a doubled hit-counter, they are vulnerable to 
punches. Punches hit extra tough enemies in a pattern of 3-2-3-2, instead of 
the usual 2/8 damage. The only exception is Burnov, who gets hit for 2-3-2-3 
by punches.

B. Stun/Knockdown/Duck

  *1. Stun Window*

The player gets stunned for .300 seconds. All enemies are stunned for .600 

  *2. Knockdown*

The player stays down for .500 seconds, while the enemies are down for 1 

  *3. Getting Up/Ducking*

Characters will take a crouching position while getting up from a fall, 
getting up from a jump, or while picking up a weapon. This state lasts for 
approximately .300 seconds. While ducking, the character will evade all 
attacks. Most enemies can duck at will to avoid attacks, except for the Ninjas 
and the Mysterious Warrior. They will typically do this in response to aerial 
attacks. The player cannot duck at will, however he can use the effect to his 
advantage through proper timing.

C. Attack Rate

Enemies attack at certain rates of speed which change in increments of .066 
seconds between difficulties. There are two attack rates, Standard and Fast, 
with a difference of .133 between them. The Standard Attack Rate refers to 
Standard enemies. The Fast Attack Rate refers to strong enemies and most 
bosses. These figures are for attacks which use 2 frames of animation. 
Naturally 1-frame attacks are faster, as 3-frame attacks are slower.

  *1. Standard Attack Rate*

Practice - .733 seconds
Warrior - .666 seconds
Supreme Master - .600 seconds

  *2. Fast Attack Rate*

Practice - .600 seconds
Warrior - .533 seconds
Supreme Master - .466 seconds

  *3. Exceptions*

 i. Burnov

He follows the guideline in Level 1, but he speeds up in Level 7 to become one 
of the fastest enemies in the game.

  Level 7

Warrior - .466
Supreme Master - .400

 ii. Ninjas

Their attack rate stays the same between difficulties, but changes between 

Level 2 - .533 (2 knife hits, 1 punch)
Level 8 - .490 (4 knife hits, 2 punches)

As noted, the attack pattern also changes between appearances. His striking 
pattern will fall into repetitions of the aforementioned combinations. Other 
than that, the patterns are the same, except for different interactions with a 
2D or 2 1/2D environment.

  *4. Player Attack Rate*

The players attack rate varies based on input. However, it is possible to 
reduce the delay to .300 seconds.

D. Attack Speed

Some attacks are faster or slower, depending on the number of frames in their 
animation. This is always the case with jumping attacks, since they are more 
complex. But this also applies to ground attacks. For example, the Right Arm's 
roundhouse kick takes longer to execute than other attacks. The Ninja's Punch 
is faster than the Knife Hit. Many attacks are not uniform in length of 
execution. Where there is a significant difference in ground-based attack 
execution, this has been noted in the enemy section. For example, two of 
Abore's attacks are described as Quick/Slow Karate Chops, respectively.

E. Ranged Attacks

Some enemy attacks are only launched from a certain distance. An enemy will 
approach or move back to the corresponding distance before using the attack. 
The distances and related ranged attacks are listed below.

Short (5 screen units) - Jump kicks by Right Arms, Williams and Ropers. Chin 
Taimei's Somersault. Ninja's Shuriken (ground)*. Doppelganger's Hadouken. 
Mysterious Warrior's Flip Kick and Flying Spinning Fist.

Long (10 screen units) - William's Knife throw. Roper's Boomerang and 
Incendiary. Linda's grenade throw.

*The 5 unit screen distance is also a trigger for other attacks by the Ninja.

While some projectile attacks go across the screen until they are stopped, 
others act differently. Roper's Boomerangs will travel 16 screen units before 
stopping and reversing. Incendiaries and grenades are thrown about 12 screen 
units before bouncing to a stop.

F. 2 1/2 D

Game areas are either 2D (two dimensional) or 2 1/2 D. The latter is a design 
that provides the illusion of three-dimensional space. In addition to moving 
left and right, you can walk up and down in 2 1/2 D areas. However, fighting 
for the most part takes place in a 2D plane - if you are slightly above or 
below your opponent, attacks will not land. However, there are a few attacks 
that can move diagonally across the 2 1/2 environment, instead of being 
restricted to a 2D plane. They are noted with (diagonal), and are as follows:

Chin Taimei - Somersault
Ninja - Running Bash, Shuriken (air)
Doppelganger - Hadouken
Mysterious Warrior - Backflip

G. Walking Speed

The player character can walk quickly, with the ability to cross a screen 
length in about 4 seconds. Most enemies are about half as fast, with only a 
few exceptions. The Doppelganger and Mysterious Warrior walk at the same speed 
as the player. The Jakes walk at the normal slow speed, but their Cartwheel is 
at player speed and their Run is slightly faster than the player. Ninjas 
always run, and are faster than the player.

H. 1-player vs. 2-player Enemy Waves

There are extra enemies to fight in 2-player mode. However, this is only if 
both players are active. If one player loses all their lives, subsequent waves 
of enemies will revert to 1 player numbers (starting with the next wave). 
Numbers in parentheses () indicate additional enemies in 2-player mode. 
Brackets [] indicate the weapon used. Angle brackets <> indicate special 
groupings of enemies. Slashes / separate the enemy waves.

For more information on 2-player mode, see IX. Miscellaneous, A: 4 & 5.

*VI. Environmental Hazards*

Throughout the game, you will find hazards in the level itself. Falling off 
cliffs, into spikes or water, or falling out of the chopper door in level 3 
will take away one life. Other hazards will do a certain amount of damage 
without being fatal, which are listed below.

2 - Chopper Bullet....4/8
4 - Spike Crushers....1 HP
5 - Bulldozer Exhaust.3/8 (shortfly)
6 - Mansion torches...4/8
7 - Flying spikes.....2/8

All environmental hazards listed cause knockdown.

The following is a list of all environmental hazards encountered in the game, 
excluding pits/spikes/water.

A. Level 2 - Chopper Bullets
Chopper bullets typically come out in a burst of 3, then bursts of 2. Getting 
hit by a bullet causes an extra bullet to fire, which can alter the pattern. 
For example, getting hit by the first 3 causes subsequent bursts to be 3 
instead of 2. Other hits can lead to a staggered stream of bullets. This is 
the same in all difficulties.

B. Level 3 - Chopper Door
The chopper door switches between open and closed. While closed, it is 
harmless. But when it is open, it actively pulls the player, enemies, and 
loose weapons towards it. Anything that reaches the open door is sucked out - 
enemies are defeated, loose weapons disappear, and it costs the player one 

The timing of the opening and closing is the same in all difficulties.

Door Open - 2 seconds
Door Closed - 6.5 seconds

C. Level 4 - Spike Crushers and Treadmills

  *1. Spike Crushers*

There are 4 Spike Crushers. They will synchronize with each other - either 
rising and falling together or in opposition, usually together. The spikes 
alternate between movement and rest, with timing windows that vary by 


Move - .600 seconds
Rest - .400

 Supreme Master

Move - .533
Rest - .333

There is a difference of about .066 between the values, which is consistent 
with enemy attack rates.

  *2. Treadmills*

At the end of the level is a screen with 2 pairs of treadmills on two 
platforms. There are pits at the sides and in between. The top treadmills move 
toward the center, while the bottom treadmills move toward the sides. In 
Warrior difficulty, the treadmills move slightly slower than you walk. In 
Supreme Master, they move at your exact walking speed. 

D. Level 5 - Exhaust Pipes
The timing and pattern of the exhaust blasts varies significantly between 
Warrior and Supreme Master difficulty levels.

 i. Timing

The exhaust blasts always last for 1 second. However, the delay between them 
differs between difficulties.

Warrior - .590 seconds
Supreme Master - .390

The .200 difference is consistent with enemy attack rates.

 ii. Patterns

To describe the patterns:
1 - The shortest exhaust on top.
2 - The medium-length exhaust in the middle.
3 - The long exhaust on the bottom.

Patterns are described in order of appearance.

  Warrior Pattern

In the beginning, there are 4 random blasts, followed by 2333. After that, the 
cycle consists of two patterns:

122333 (3 reps)
112333 (4 reps)

After each cycle, there is an extra 3, and then it loops.

  Supreme Master Pattern

In the beginning, there are 5 random blasts. This is followed by 5 reps of the 
first pattern, and it follows normal cycles after that.

There are three patterns in the cycle:

321 (5, then 8/7 reps)
331 (4/3 reps)
332 (3/4 reps)

There is an extra 3, then the cycle loops.

The repetitions vary in their own pattern from one cycle to the next. The 
first cycle is 5/4/3, the second is 8/3/4, the third is 7/4/3, and so on.

E. Level 6 - Torch Flames and Platforms

  *1. Torch Flames*

The timing and pattern of the dripping torch flames vary between Warrior and 
Supreme Master difficulty levels.

In Warrior, the delay is 2.5 seconds.
In Supreme Master, it is 1.5 seconds.

To describe the patterns, the torches are labeled thus:

1 - The lower torch furthest to the left, above the spikes.
2 - The torch in the middle.
3 - The torch furthest to the right.

Warrior Pattern: 1132
Supreme Master Pattern: 1123

Both patterns loop indefinitely.

The other two torches by the icon are harmless.

First Screen:

            2   3            
        1   \/  \/  %%%%     
        \/        ..%%%%..

__           ||  || \\||//___S__
//           ||  ||   ||  \\||//

Second/Third Screen:

       ==  ==                
       __________  ________--___
         \\||//     \\||//    \\
^^^^^^^^^  ||  ^^^^   ||   ^^

The relevant screens are illustrated in ASCII above. They are 32 characters 
horizontal and 12 lines vertical, giving a close approximation to the game.

^^^^ - spikes
____ - solid ground
---- - solid platform
==== - fading platform
 \/  - torches. With a number above, a dripping torch.
  S  - the starting point.
#### - the exit door.

The rest are decoration.

  *2. Disappearing Platforms*

While the platforms don't cause damage, their disappearance can drop you onto 
spikes, costing you one life. The timing and pattern of the platforms are the 
same between difficulties. There is no delay between the disappearance of one 
and the appearance of the next. The time windows of the platforms are 
consistent within each screen, and are as follows:

First screen - 1.5 seconds
Third screen - 2 seconds

On the first screen, the platforms change in a counter-clockwise pattern. On 
the third screen, they change from bottom to top in sequential order.

There is always only one platform on the screen at a time.

F. Level 7 - Treads, Bridges, Flying Spikes and Gears

  *1. Treads*

The treads appear in this layout:

           1              ####  
               >>>>  <<   ####  
                2    3    ####  

The ASCII illustration has 32 characters horizontal and 12 lines vertical, so 
it is approximately proportional to the game.

^^^^ - spikes
---- - solid platform
<<<< - tread moving left.
>>>> - tread moving right.
  S  - the starting point.
#### - the exit door.
%%%% - background/decoration

The ASCII indicates the direction the treads move you in - left for 1, right 
for 2, and left for 3. The treads move about half as fast as you walk.

  *2. Bridges*

There are two bridges, both have the same properties. They collapse from left 
to right, one segment at a time. 25 segments disappear, with a total of 31 on 
the screen, which leaves a small platform on the right at the end. There is 
one segment off-screen to the right, so the total is 32.

The speed of collapse varies between difficulties. Here are the values for the 
length of time a segment stays on screen.

Warrior - 2.3 seconds
Supreme Master - 1.9 seconds 

  *3. Flying Spikes and Gears*

This is the layout of the gear room:

 ####   ..               --II   
-------{5v}  --  --   ..   II   
                     {v4}  II   
 %%%%                      II   
 %%%%             ..       II   
 %%%%        ----{v2}      II   
 %S%%   ..            ..   II   
-------{1v}          {v3}  II   
       1   5   2   4   3

The ASCII illustration has 32 characters horizontal and 12 lines vertical, so 
it is approximately proportional to the game. The flying spikes are not shown, 
but are lined up with the numbers at the bottom.

^^^^ - spikes
---- - solid platform
{  } - gears. The v indicates the direction of turning.
 II - the ladder.
  S  - the starting point.
#### - the exit door.
%%%% - background/decoration

 i. Spikes

Spikes fly up from the bottom of the screen in a fixed pattern. Referring to 
the diagram, the flying spikes are labeled in the order of their appearance, 
from 1-5. The pattern is the same in both difficulties and continues 

The spikes stay on the screen for 1.6 seconds in both difficulties. The only 
difference between difficulties is in the pause length between spike launches, 
as described below:

Warrior - 1.5 seconds
Supreme Master - .5 seconds

 ii. Gears

Each gear consistently turns clockwise or counterclockwise. They turn in two 
groups, upper (4, 5) and lower (1, 2, 3), taking turns consecutively. The 
upper gears turn for 2 seconds. In the lower set, gears 1 and 2 turn for .6 
seconds. Gear 3 starts turning .2 seconds early, so it turns for .8 seconds.

Turning speed is determined by difficulty. In Warrior, the gears turn exactly 
as fast as you walk, allowing you to resist the motion. In Supreme Master, 
they turn slightly faster than you walk.

Individual gears are described below with their orientation, # of revolutions 
for each turning, time window, and unique characteristics.

Gear 1 - Clockwise. 1 2/8 revolutions. .6 seconds. Reverses by 1/8 at the 
         start of turning.
Gear 2 - Counter-clockwise. 1 7/8 revolutions. .6 seconds.
Gear 3 - Counter-clockwise. 2 2/8 revolutions. .8 seconds. Starts turning .2 
         seconds early.
Gear 4 - Counter-clockwise. 2 2/8 revolutions. 2 seconds. Reverses by 2/8 then 
         moves forward by 1/8 at the end of turning.
Gear 5 - Clockwise. 2 1/8 revolutions. 2 seconds. Reverses by 2/8 at the end 
of turning.

*VII. Point Scoring*

Throughout the course of the game, you can add points to your high score by 
landing attacks. Here are the point values for all attacks.

Any attack with a weapon - no points
Knee stun - no points
Kick - 10 points
Punch - 10 points
Jump kick - 30 points
Knockdown kick - 100 points
Knockdown uppercut - 100 points

Shopping cart:
Using the hold - 20 points
Kick - 10 points
Elbow - 20 points
High kick - 30 points
Throw - 50 points

Cyclone kick - 500 points
Hyper uppercut - 500 points
Flying knee - 500 points

*VIII. Naming*

I have included various names for the enemies and bosses. My naming convention 
is to include all relevant names, as well as names I made up in childhood. The 
official names are on the left, my made up names are on the right, and 
alternate unofficial names that are frequently used are in the middle and/or 

  *A. Made-up names*

Crossing Guards
Fading Helmet Dude

  *B. Unoffical names*

Martial Artists
Shadow Clone
Shadow Master

  *C. Official names*

Migiude(Right Arm)
Chin Taimei
Mysterious Warrior

Migiude is Japanese for Right Arm. See IX. Miscellaneous, C: Japanese 
Translation for more information.

Bolo is frequently referred to as Abobo, as he does look very similar to that 
boss from the first Double Dragon game. However, he is officially known as 

The final boss is officially known only as the Mysterious Warrior, but "Shadow 
Master" is the best and most descriptive name I know of.

I have tended to use the plural form for unofficial enemy names.

Names for weapons and attacks are for the most part my own invention, with 
some influence from the official names in the instruction manual.

*IX. Miscellaneous*

A. Random Facts and Oddities

1. The screen is divided into 32 units horizontally, and 24 units vertically.

2. Every time you go through a door and change screens, your health is 
refilled. This happens once in Level 4, and four times in Level 8.

3. Whenever enemies drop a weapon that they can recover, they will walk 
towards the weapon to pick it up, ignoring everything else. They will duck to 
pick it up even if the weapon is removed.

4. In two-player mode, enemies will focus on one of the players while ignoring 
the other. Typically, two enemies will focus on both players respectively, and 
enemies tend to focus on player 1 first. This can be used to your advantage.

5. In two-player mode, the players must be in proximity for the screen to 
scroll properly. When going down to a new area, a player can lose a life 
unless both descend at the same time. For this reason, using ladders is 
recommended for 2-player mode.

6. Boss enemies cannot climb ladders. Standard and Strong enemies can all 
climb ladders, with the exception of Chin Taimei. Going up a ladder against a 
Chin or a boss will result in them freezing in place until you are within 
reach again. It should be noted that characters can be hit while on ladders. 
It is not known whether the Doppelganger can climb ladders.

7. Ninjas can be tricked into falling off the screen in both appearances. In 
stage 2, they disappear if they travel too far to the left. In stage 8, they 
can fall down the pit at the bottom of the screen.

8. Ninja jumps can bounce off of walls.

9. Grenades cause no damage to a target when they are stunned, only knockdown.

10. Occasionally, enemies throw two weapons in rapid succession. This applies 
to all enemy thrown weapons - knives, grenades, boomerangs, incendiaries, and 
Shuriken. I am not as certain about the Shuriken due to the Ninja attack 
pattern, but they seem to fit (see X. Notes 5 for more info). This effect can 
occur in any difficulty.

9. At the chopper fight in level 2, you can knock the enemies onto the lower 
rooftop on the right. If you do, they will automatically jump off.

10. Chin Taimei use Kali sticks for fighting, making them practitioners of 

11. When Burnov fades out, his helmet makes a clanking sound when it hits the 
ground, just like knives. The fade effect usually drowns it out in the noise 
channel, but pausing and unpausing beforehand will let you hear it.

B. Glitches

1. There is a dramatic glitch in Level 1, which can be triggered when fighting 
the Jakes equipped with knives. You take a knife and throw it off the left 
side of the screen. The Jake will walk to the left, and you follow him. Once 
he reaches the step, he will walk diagonally up the wall. Once he is above the 
door, he will duck to pick up the knife (which briefly flashes under him), 
before teleport-jumping to ground level.

2. In Level 8, a glitch can be triggered where you fight the three bosses. If 
you jump off the bottom of the screen right after defeating a boss, the next 
one will walk in on the very bottom of the screen with only his head visible. 
To trigger it, you must jump while the previous boss is in his last frames of 
flickering, before he disappears entirely. This will prevent you from 
advancing in the level.

C. Japanese Translation

This section will describe the meaning of all Japanese, as well as the 
relevant Romaji and Unicode designations. Romaji is in On reading unless 
otherwise stated.

The three characters on the title screen mean "Twin Intercepting Dragons". The 
Romaji is Sou-Setsu-Ryuu. Unicode is U+53CC U+622A U+9F8D. The first Unicode 
designation is for the Kanji equivalent, since the first character is in 
cursive/Sousho form.

The enemy name Migiude is Japanese for Right Arm. More specifically, the 
Romaji is "Migi Ude". This can be translated literally as Right Arm, but more 
accurately as "Right Hand Man", or reliable henchman. After all, "Ude" can 
also refer to wrist. Interestingly, this is in Kun reading. Unicode for the 
corresponding characters is U+53F3 U+8155. 

The Lee's martial arts style is Sou-Setsu-Ken, which means "Twin Intercepting 
Fist". Unicode for the corresponding characters is U+53CC U+622A U+62F3.

The Mysterious Warrior's martial arts style is Gen-Satsu-Ken. Possible 
translations include "Phantom Killer Fist", or "Illusion Assassination Fist". 
Unicode for the corresponding characters is U+5E7B U+6BBA U+62F3.

*X. Notes*

1. Knockdown attacks usually move the target a short distance. However, it is 
possible for an "improper knockdown" to move the target an even shorter 
distance. This can happen in various ways - a knockdown uppercut delivered in 
the opposite direction of the initial attack will often cause this. A regular 
punch or kick that causes knockdown will have this effect as well.

2. The first two Ropers in Level 2 can throw boomerangs in Supreme Master 
difficulty. They may be equipped with boomerangs in lower difficulties, but I 
have been unable to prove this. Because boomerangs are thrown from half a 
screen length, they only use them if they are standing on one edge of the 
building with you on the opposite edge. Jumping off the building while the 
Roper is far back can cause this more easily. In normal gameplay, you will 
usually not encounter this, although the difference in movement patterns can 
be seen.

3. The first Roper in Level 5, on the platform, is a strange case. It is 
certain that he has 1/8 HP at maximum. It is possible that he has no HP - if a 
character loses all HP, they are only defeated after being knocked down. Since 
I cannot knock down an enemy without doing at least 1/8 damage, this is one 
point I am not certain of. It is notable that this is the only enemy that 
doesn't get the uniform 3/8 boost in Supreme Master. The way I tested this, by 
the way, was getting close to him while he was punching - then I walked 
through him as he jump kicked, so I could kick him from behind while he was in 
the air. This knocked him down with 1/8 damage.

4. As a general rule, I have ordered all damage value lists from least to 
greatest. The damage value list for Linda is the single exception. Normally, 
3/8 would be listed after 3-2-3-2 - however, I switched them to keep the two 
weapons next to each other.

5. In the case of Chin Taimei and Ninjas, it was somewhat difficult to 
classify weapons. Chins use Kali sticks; but they're always equipped, used for 
regular attacks, and do not cause knockdown. All other weapons are sometimes 
equipped, distinct from regular attacks, and cause knockdown. Based on this, I 
decided that the Kali sticks could not be categorized as a weapon. However, 
the Ninja presented difficulties. The knife is just like the Kali sticks, but 
the Shuriken are different. The player can't use them, but the Boomerangs also 
can't be used. They are used two different ways, but so are Pipes. The latter 
pair of Ninjas in level 8 typically don't use them, so they're not always 
equipped. Also, Shuriken seem to be consistent with the occasional rapid 
throwing seen with other weapons, although this is difficult to determine due 
to the attack pattern. Based on this, I have decided to classify Shuriken as a 
weapon. It should be noted that the Hadouken attack of the Doppelganger is not 
considered a weapon, even though it is a projectile. It doesn't fit the 
characteristics, although it is used in a similar way to weapons. I could be 
wrong, but that's my judgment for now.

*XI. Addendum*

In compiling this data, I had no help from the source code or programmers. All 
information came entirely from gameplay experimentation. I was very thorough 
and exacting in gathering the values, however, I cannot be 100% certain that 
all information is complete and correct. If you find any errors or omissions, 
feel free to contact me at bigdan201 [AT] yahoo . com (remove spaces).

In particular, I would like to know more information about enemy AI/attack 
patterns and precise in-game timing windows.

With that said, I am confident in the veracity of this guide. In particular, 
patterns such as the universal 3/8 enemy HP difference between Warrior and 
Supreme Master lend credibility to my results.
