Re: Video: Lesson P31 - Hardware Sprites on the MSX1!
"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...

Re: Video: Lesson P5 - Bitmap graphics on the TI-83 and MSX
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 gam...

Re: Video: Lesson P5 - Bitmap graphics on the TI-83 and MSX
Hello Keith, According to https://www.msx.org/wiki/SCREEN screen 3 is the only true bitmap mode (screen 1 and 2 simulate bitmap modes with tiles) for the MSX 1. Do you show anywhere how to use screen 3 MSX? I am looking how to plot a pixel,with a chosen colour, in screen 3 using assembly. Of course ...

Re: Video: Lesson P31 - Hardware Sprites on the MSX1!
Hello Keith, I recall I read it somewhere but don't recall where as it was so long ago. If I can remember the reference I will let you know. Early 1980s home computers , for example, like the MSX and ZX spectrum and others a main application for them computers was text applications (e.g. business ap...

Re: Video: Lesson P31 - Hardware Sprites on the MSX1!
Hello Keith, I don not understand why you say words that mean you need to use a buffer for MSX-1 scrolling up an down (vertically) and/or there is no hardware scrolling on MSX-1 machines in your recent video Lesson P59 - Hardware scrolling on the MSX 1/2/2+ at https://www.youtube.com/watch?v=-vKt68T...

Re: Video: Lesson P35 - Playing Digital Sound with WAV on the AY!
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. . The problem is...

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 Programstart: call INIT32 ; SCREEN 1 Programstartwithoutclearscreen: ld de,12...

Re: Video: Lesson P31 - Hardware Sprites on the MSX1!
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 usi...
