"If you can't keep your program below 16k, I think one way or another you're going to have to learn about bank switching."

Now I understand how to do bank switching and hence I am paging in the
required 16K memory to show the screen. So I can now show the desired background image using all three ...

Hello Keith,

This question is regarding your Chibisound described at

https://www.chibiakumas.com/z80/platform2.php

for the MSX 1 you describe loading the mixer register,which is register 7,

A game entry into msx-dev twenty has a 64x48 screen 3 game and it looks great

Yeah, screen 3 is 64 columns by 48; and in addition in can still display some high resolution using the 32 sprites in screen 3. Because it does not use tiles it makes it easier (and uses less memory) to program some type of games in 16 colours such as 3D games (lacking on the MSX-1) or pseudo 3D ...

Hello Keith,

According to

https://www.msx.org/wiki/SCREEN

Early 1980s home computers , for example, like the MSX and ZX spectrum
and others a main application for them computers was text applications

Hello Keith,

I don not understand why you say words that mean

I have been learning z80 assembly using this site
and using the method of using OpenMSX,VASM,Winape to develop
code. But this method does not work for Arkos Tracker 2.
I have attached a minimal example of using Arkos Tracker
2 for the MSX and it plays a song in the OpenMSX Emulator.

Hi Voyager_Sput,

Thanks . But there is another more subtle bug when I tried to use this code for animating sprites. Adding a simple infinite loop to the code , the relevant changes to the code is shown below, shows the bug

Hi,

I have gone through your tutorial (video and the writing) of
using tiles for simulating sprites on the MSX-1.
I have copied and pasted your code ,from
your files, into a simpler cartridge program that
has only MSX1 code-
(instead of leaving in all the code for all the
different platforms and ...
