Re: PDP-11

Fantastic work! I'll be taking a look at this over the week, and trying to get an understanding of it!

I'm hoping to do some more PDP-11 on my friday livestream, so hopefully I can make some more progress thanks to your help here.

Re: Video: Lesson P10 - Tilemap graphics on the MSX1

I've made a new tutorial covering the use of 768 tile MSX1 mode to show a full screen color image on the MSX1 I've also upgraded akusprite editor so it outputs a second file with the color information in addition to the Black and White bitmap https://youtu.be/pobGYc2iPfE http://www.chibiakumas.com/z...

Re: Setting CRTC

The Amstrad code works in pixels, so the screen is 320x200 My code works in Bytes, so the screen is 80x200 Using just one bytes for co-ordinates is more efficient, as the 8 bit cpu works with bytes faster than words, but your characters will probably move too fast across the screen... Oh, and if you...

Re: Video: Lesson P10 - Tilemap graphics on the MSX1

Lesson 10 used AkuSprite Editor to create a tile image onscreen, but it only used the 256 tile limited mode, not the one spit into 3 https://www.chibiakumas.com/z80/platform.php#LessonP10 I will make an example for you of loading an image that uses 3x256 tilemaps - however please note AkuSprite Edit...

Re: Lesson H3 - Hello World on the MSX / MSX2

I'm sorry, I can't help you with this, I'm only a software person... I've no experience of circuit design, my MSX game was released on floppy disk Maybe someone else can advise, but I think you'll have more luck on MSX.org - there's a lot of MSX specialists who can point you in the right direction f...

Re: I'm new

I mis-spoke when I said DevTools.7z - the file you extracted was correct, but when I did it, it worked, I can only assume something is going wrong on your machine... I can't help you any more at this time, I can't work out what is wrong, there's too many possible factors. I will create a new set of ...

Re: Final Fight CPC (VERY early demo video)

That looks great! The animation is fantastic, and the sprites don't look like they've suffered from recoloring/resizing. Things will certainly get slower when you add backgrounds and other sprites, music etc, but they'll also get faster as you learn better ways to code things - so I wouldn't worry a...
