Hi Nephesh, If you didn't understand Keith's explanation I will add a little more to it so maybe you can understand it. To convert a hex value to an ASCII letter first notice that in the ASCII table there is a gap, of size 7,between the two groups of characters 0 to 9 and A to F, this obviously sugg...

I had a read of some of documentation screen 3. The screen three mode (as it is known in MSX BASIC) can have 16 colours on screen and each pixel in the the 68 by 48 screen can be set to any of the 16 colour without any restrictions. The common definition of bitmap means there is a one to one corresp...

All right. Personally, to be frank, I would not sponsor you to do it-if that what your reply above may mean-because the reason but I am unable to do it, for now, is because I can't find any information,so far, on it on how to plot a screen 3. I can't find any information,so far, on it on how to plot...

I did my own pixel plot function for the MSX1 in screen 2 a few months ago, and I used it for that basis of lines, then 3d wireframe models, but I found it was too slow for such 3d graphics. I came to the conclusion that coloured 3d wire frames graphics on MSX1 can be done at a good speed in MSX1 sc...

Hello Keith, This is regarding the Akusprite image conversion to MSX1 screen 2 (the 8x1 color node), when I am doing a conversion from akusprite , so akusprite generates the exported files .RAW and .RAW.COL, of the test image for MSX1 screen 2 in 8x1 color , the colors are not what I expected; the t...

The problem I am having for completing a game is making Arkos Tracker 2 work properly I mention the problem at the page Video: Lesson P35 - Playing Digital Sound with WAV on the AY! I guess the issue is CBIOS differs from the real MSX 1 BIOS in a way that makes Arkos tracker 2 fail on a real MSX 1 (...

"Unless you have some clever ideas to exploit this (like objects that move with the screen - staying in their 3rd)" I have though about this again. I do not think you need clever ideas to do vertical scrolling if that is what you meant in your video lesson P52 (https://youtu.be/pobGYc2iPfE...

Hello Keith, I think there may be a bug in akusprite. So I have a 16x16 BMP test image (imagetoconverttomsxtiles.bmp in the zip file attached) to convert to MSX 8 by 8 pixel tiles,with 8 bytes in a tile to demonstrate the problem; thes test image is also shown as a png image in this message. The pro...

"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...

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, with the value --NNNTTT. Don't you need to set bit 7 to 1 and bit 6 to 0 when setting the mixer register (regi...
