Per the main readme, "chapters 4 and 5 are split in two files each due to their size". Is that still appropriate more than 20 years after your original transcription?

Posed as an issue in order to find out what the thinking is.

Chapter 5a
Table 5.1

D# Octave 5 is 0xB4 instead of 0x84

Seems a OCR fail.

En uno de tus ejemplos, tienes esta línea:

1160 LINE (I+33),0)-STEP(0,120),15

la correcta es:

1160 LINE (I+33,0)-STEP(0,120),15

The document used for the MSX-BASIC Kun manual is also released with a disk from sparrow soft in 1988, but in that document the year is 1986. But in both documents they say there are three new commands (#C, #I, #N), but I wonder if this is translated correct since it looks like these commands are already available in the first version.

Also there are three versions:

• MSX-BASIC Kun
• MSX-BASIC Kun Plus
• MSX-BASIC Kun Turbo

I found the original ASCII docs of the last version (in Japanese):
basicn1.txt
basicn2.txt
basicn3.txt

Hello, I tried out the code in chapter 3.2 and the resulting file had 0 bytes.
Seems like the CLOSE statement is missing.
Is it also missing in the original?

At Chapter 4 Section 6 List 4.23:
https://konamiman.github.io/MSX2-Technical-Handbook/md/Chapter4b.html#list-423--example-of-using-the-paint-routine

These lines aren't correct:

1190 LINE (X-5,I)-(X+5,I),15,,XOR
...
1300 IF STRIG(9) THEN GOSUB 1320

The correct ones are:

1190 LINE (X-5,Y)-(X+5,Y),15,,XOR
...
1300 IF STRIG(0) THEN GOSUB 1320

I don't know what this appendix is like, but some time ago I made a table in HTML (it is also available in PDF), with the table of characters with the international codes.
It is at your disposal, to adapt it to the format of this document or I am also available to make any changes you need.
(Sorry for my bad English).

https://github.com/mvac7/MSXhardware_gfxResources/blob/main/MSX_character_set_vertical.pdf

There's this bit of code:

        LD      A,L                     ;make NY and DIY
        SUB     A

To make it work (at least for my usecase), this should be:

        LD      A,L                     ;make NY and DIY
        SUB     E

For reference, I'm scrolling the screen up by 8 pixel rows:

    ld      bc,0
    ld      l,8
    ld      e,192
    ld      d,2
    call    ymmm

Great job, thanks a lot Konamiman!!!
But any chance we can see it PDFized, so I can have it in my library in just one file and formated to print?
Thanks!

Missing some data and when added data, does not work in some cases.

Invalid is : SUB A
should be SUB A,x (D / E)

when copying 0,0 - 240,10 to 10,0... fails (in OpenMSX, not checked yet on real MSX)
you need to reverse 240,0 - 0,10 to 10,0 works (very slow, if DIX and DIY is set correctly)

Also size of NX and NY result is incorrect.

Routine should be rewritten. (by ASCII)

In Appendix 4 the address of MUSICF (FC3FH) is not correct.
It should be FB3FH.

And thanks for your work, BTW :)
