Hydlide Story

In the kingdom of Fairyland, three magic jewels were enshrined in the palace 
to maintain peace in the kingdom. One day, an evil man broke into the palace
and stole one of the three magic jewels. Without the third jewel, the two 
remaining jewels lost their magic sparkle. The magic spell that sealed the
power of Boralis, the most vicious demon in the kingdom, was broken. During 
the turmoil which followed, the last two jewels were stolen. Boralis cast a
special magic on Princess Ann, turning her into three fairies, and hid her
somewhere in the kingdom. He then let loose a horde of monsters across the
land and became the ruler of the kingdom.

Finally, the young knight Jim stood up and took action to restore peace in the
kingdom. He bravely made his way into the wilderness in full armour to fight
the monsters...

Name of the Parts on the Screen

Each bar on the meters represents 10 points.

1. Life Meter
This indicates the level of Jim's life power and shows the damage he receives.
When his life power reaches 0, he is defeated.

2. Strength (STR) Meter
This indicates the level of Jim's strength. The more powerful he becomes, the
more damage his enemies receive.

3. Experience (EXP) Meter
This indicates the level of Jim's experience. The Experience level increases
each time Jim destroys a monster. When Experience level reaches 100, each 
level of Life, Strength, and Magic also increase by 10 points, and the
Experience level returns to 0 again.

4. Magic Meter
This indicates Jim's Magic Power. Each type of magic requires different levels
of Magic Power. The level of Magic Power decreases more quickly when high-
powered magic is used. But you can build Magic Power back up.

5. Information Area
This area indicates the level of the monster's Life Power and of their damage
when attacked by Jim. It also shows treasures when they are discovered.

6. Magic Select
Press Button B to move from one type of magic to another. To execute, hold 
down Button A while pressing Button B. The five types of magic are: Turn, 
Fire, Ice, Wave, Flash. You can begin to use magic when the magic meter
reaches 20.

7. Condition Area
This area shows the sign ATTACK when Jim attacks, and DEFEND when he is on the

8. Message and Password Area.
This area indicates a message to Jim and shows the Password.


Mode Window

Press the Select Button and the Mode Window will open. Move Arrow with Button
+, and press either the Select Button, Button A or Button B to choose which
mode you will open.

This indicates the treasures Jim finds during his adventure.

You can save the data recorded on all the meters (Item, Life, Strength,
Experience, Magic) until you turn off the power. Whenever you save the game,
the data is automatically registered in the program. If you want to save this
data, set arrow to Yes. If you don't set Arrow to No and push Button A or
Button B.

This is used to load the saved data onto each meter at the beginning of a new
game (before the power is turned off). Press the Select Button immediately
after starting the game to open the Mode Window. Set Arrow to Load. Press
either Select Button, Button A or Button B. Set arrow to Yes when you want to
read the data. If not, set it to No. You can start the game again from the 
same situation you saved before Jim was defeated. You will begin with the same
levels for Item, Life, Strength, Experience, and Magic meters.

This is another way of saving the data. Unlike Save, you can start the game
once you input the Password, even after you have turned off the power once. 
Although Experience level goes down to 0 when you input the Password, you can
save the location and items for when you start playing the game again. Write
down the fourteen letters that appear at the center of the Password Window
before turning off the power.

How to Input Password
Input the password you recorded on the Password Screen. Position Jim at the 
top of the first letter of the password with Button +, and press either Button
A or Button B. The letter will appear in the password area. Repeat the same
procedure for the rest of the thirteen letters of the password. After input-
tine the fourteen letters, Jim will automatically move to the top of the end
sign. Make sure you input the right password and press either A or B Button.
Now you can start the game again under the same situation you had when you
stopped the game. If you input a wrong letter, position Jim above the Arrow
and input the correct letter.

You can change the speed of the game. Normal is a slow speed and is for begin-
ners. With this speed, you play the game on a scrolling screen. high Speed is
for advanced players. The screen will switch from one scene to another 
instantly and each movement on the screen gets faster.

When you press Select button by mistake, set the Arrow to Game and press 
either Select Button, Button A or Button B. The Mode Window closes and the 
game resumes.


Treasures and their Powers

You may find treasures and treasure boxes during the adventure. Some treasure
boxes are hard to get, and some are even hidden.

Sword of the Brave
The legendary sword that is said to be kept only by the brave. With this 
sword, attacking power doubles.

Shield of Justice
The legendary shield that is said to increase its defense power only if used
by a person with a strong sense of justice. This shield was stolen from the
court when the kingdom collapsed.

This cross was once kept at a chapel in the kingdom. Someone hid it for fear
of its power. Guess what you can use this cross for.

Magic Vase
This is one of the items in which the magician in the kingdom hid a magical
secret. If you get this vase, you will be able to see something that has been

Eternal Lamp
This is an item the magician in the kingdom used to keep for his own use. It
remains eternally aflame. Even in the complete darkness, this lamp will 
brighten up the surroundings so you can see everything.

monsters. You can use this medicine only once during the game.

Hints for a Successful Journey

- When you walk in the kingdom, watch your step at all times. If you try too
  hard, you'll tire easily.

- Jim wears very heavy armour. Think what will happen to him if he has to swim
  for too long.

- Be smart when fighting with monsters. You have to think of a strategy when
  fighting against a powerful monster.

- Attack is not the only way to destroy monsters. Do not forget to use Defend.

- Be sure to investigate the forest completely.
