The game:

This is the land of rats. Some hundreds of years ago, a terrible monster appeared here and took over this country.
The hero of that time, "Nezumikkun," sealed those monsters with the power of mysterious stones called "Nezumikkun's Stones".
However, the seal has now been broken, and the country has once again become a den of monsters.
At that time, two people happened to appear. The rats asked them to exterminate the monsters.
Fortunately, they gladly accepted the request and set out on a journey to exterminate the monsters.

The 1st file:

Particular attention should be paid when typing following lines.
nezumikkun-1st-file-lines
Modify the line #2930 to add the extension. I'm assuming that we're managing a huge amount of MSX games' files.
If you modify the code as described above, each checksum will change as follows (using version 3.1 coded by the "MSX•FAN" team).
nezumikkun-1st-file-checksum
Sorry if there are any typos, however, I have tested my data, including the ending, and had no problems.

The 2nd file named "NEZU-2.BAS":

Particular attention should be paid when typing following lines.
nezumikkun-2nd-file-lines
In addition, the lines #1550, #1750 and #2710 include CHR$(161), not CHR$(46), I think.
The line 1370: "NEZ" string should be also included, not only "MAP-". I'm assuming that we're managing a huge amount of MSX games' files.
Correct the author's typos. This is because "SLIM" and "SLIME" are words with completely different meanings.
nezumikkun-2nd-file-typos
If you modify the code as described above, each checksum will change as follows (using version 3.1 coded by the "MSX•FAN" team).
nezumikkun-2nd-file-checksum
Sorry if there are any typos, however, I have tested my data, including the ending, and had no problems.

The 3rd file:

Particular attention should be paid when typing the lines #530 and #540.
In addition, the lines #30 and #180 include CHR$(161), not CHR$(46), I think.
nezumikkun-3rd-file-lines
Modify the line #210. "NEZ" string should be also included, not only "MAP-". I'm assuming that we're managing a huge amount of MSX games' files.
If you modify the code as described above, each checksum will change as follows (using version 3.1 coded by the "MSX•FAN" team).

How to start the game:

First, load the 3rd file and type following.
RUN100
"NEZ-MAP1.DAT"~"NEZ-MAP6.DAT" will be created on the same diskette.
Then run the 1st file. Choose "MAKE CHARA". Enter your 2 characters' names and the file name.
Suppose your file name is "NEZ-SAVE", then "NEZ-SAVE.NDT" will be created automatically on the same diskette.
Finally choose "GAME START". Choose which of the two characters you would like to control now.
At this starting point, you can select a character and save the game by pressing the Esc key.
(Every the game was saved, your ".NDT" file would be updated.)
From the next time, simply run the 1st file and choose "GAME START".

My suggestions for English version:

The 1st file:
nezumikkun-1st-file-en-suggestion Checksum: UiM0

The 2nd file:
Modify following lines, first.
nezumikkun-2nd-file-en-suggestions-part1
Then type following!
nezumikkun-2nd-file-en-suggestions-part2
If you modify the code as described above, each checksum will change as follows (using version 3.1 coded by the "MSX•FAN" team).
nezumikkun-2nd-file-checksum-en-version

The 3rd file:
nezumikkun-3rd-file-en-suggestion Checksum: 180>EbC0   190>SL30   260>5ta0
nezumikkun-en-screensFully tested!
For modern emulator users:
It recommends to hold CTRL key when you turn on MSX to disable the 2nd disk drive.
This is because this English version gives an "illegal function call in 1510" error when advancing toward the breakable wall with no hammer.
I could not confirm any other glitches, so it is not that much of a concern.

Joystick support:

The 1st file:
"STICK(0)" is found in the line #2520.
"STRIG(0)" is found in the line #2540. The quickest way is to simply replace each "0" with "1".

The 2nd file:
"STICK(0)" is found in the lines #410, #600, #800 and #2010.
"STRIG(0)" that you must modify is found in the lines #460, #820, #960, #1300, #1590 and #2010.
The quickest way is to simply replace each "0" with "1". In addition, modify following lines.
nezumikkun-2nd-file-joystick
Now you can use Trigger 2 instead of ESC key or Return key while the gaming.
Of course you can delete the line #350 and "STRIG(0)ON" / "STRIG(0)OFF" to shorten the code itself.
"STRIG(0)ON" / "STRIG(0)OFF" is found in the lines #360, #580, #850, #880, #970, #1030, #1040, #1060, #1320, #1370,
#1550, #1770, #1900, #2290, #2430, #2550, #2630, #2640 and #2670.
For SNES+AD adapter users:
nezumikkun-gba-screen MSXAdvance doesn't cause "illegal function call in 1510" even if you didn't delete "STRIG(0)ON" / "STRIG(0)OFF", though!
