Release:	"MSX Magazine" Nov. 1987 Issue

Space: Release flames(Player 1), Trigger1: Release cold air(Player 2), ESC: Go to the "Continue/Quit the game" screen.
Enter: Show items / Exit the store(Player 1), Trigger2: Show items / Exit the store(Player 2)
A key and B key: Choose an option(1P mode / 2P mode, Buy a key / a heart item, Continue the game / Quit the game)

Note:

You need to create 2 Basic files and 2 memory dump files first, then run the first Basic file.
CD32 users must load the game on MSX1 mode, otherwise nothing happens after the title screen.
"Basic Kun.rom" that attached to AmiMSX2 must be selected for "Slot 1:".
Choose "MSX1" and click "Power ON", then swap diskettes at the MSX Basic screen.
This way, you don't have to type "CALL BC" in advance, just type the following:
LOAD"WORLD.BAS",R

To detect your typo, use version 3.1 coded by the "MSX•FAN" team, however,
this time you have to modify each line number because the 2nd Basic file uses 9000s lines.
So an example is "CHECK65K".

The 1st Basic file named "WORLD.BAS":

Issue 1: It doesn't show "NOW LOADING!!" message.
My suggestion: Modify the line #110 as follows then delete the line #1020.

Issue 2: The rock's graphics seems corrupt.
My suggestion: Modify the lines #20140~20170 as follows.

The rock's graphics data is in lines #20140~20170.
It consists of 4 lines(=4 tiles). Each tile consists of 8*8=64dots, however,
you can see only 32 characters per 1 line.
This means that a set of four characters refer to 8 dots in a horizontal row.
The first 2 characters refer to the placement of 8 dots in 2 colors,
and the remaining 2 characters refer to which color the 2 colors are.

Issue 3: A part of the flame sword of Player 1 becomes blue that seems strange (at the item screen).

My suggestion: Modify the lines #20380 as follows.

The flame sword's graphics data is in lines #20380~20390.
Actually the matter is the 3rd set of the first tile (=line #20380).

If we modify the code as described above, each checksum will be following:

I tested the above modified data, including the ending, and had no problems.

The 2nd Basic file named "WORLD.MIN":

Particular attention should be paid when typing lines below.

Issue 4: After the player dies and choose "END", characters mess up at the MSX Basic screen.
My suggestion: Modify the line #9140 as follows.

Issue 5: After type any key(s) at the ending screen, characters that mess up appear.
My suggestion: Add the line #11550 as follows to return to the title screen.
11550 RUN
If we modify the code as described above, each checksum will be following:

I tested the above modified data, including the ending, and had no problems.

The 1st memory dump file named "WORLD.MAP":

Use "Monitoring RAM" code that "MSX Magazine" team coded.
Don't forget to compare each checksum with that in the magazine.(Type "DB800".)
Save the file typing following:
BSAVE"WORLD.MAP",&HB800,&HC207

The 2nd memory dump file named "WORLDBGM.PLY":

Use "Monitoring RAM" code that "MSX Magazine" team coded.
Don't forget to compare each checksum with that in the magazine.(Type "DD870".)
Save the file typing following:
BSAVE"WORLDBGM.PLY",&HD870,&HDE1F

How to play:

This game is action RPG where you control two main heroes at the same time.
You may want to choose the 2P mode even if you are playing alone.
One warrior can attack by releasing flames and the other warrior can attack by releasing cold air.
Each time you defeat an enemy, your maximum HP value will increase.
Trees and rocks turn into items once they are frozen by cold air and thawed by flames.
Items include blue keys, money, and hearts (that recovers HP).
Blue keys and hearts can also be purchased in stores.
To find the breaking walls and hidden bridges you'll need to freeze them once.
Be careful of their collision detection.
Toward a suspected location, release cold air at various distances.
The objective of the game is to get the six diamonds hidden in this world and defeat the final boss that awaits beyond the red door.

Joystick Support:

Originally, it supports Joystick for the 2nd player if 2 players mode was selected.
However, in 1 player mode, only keyboard was available.
Modify the 2nd Basic file as below.

For modern emulator users, if you got an "Out of memory" error, delete the line #11105 or modify the line #130 more. Thanks in advance.
