If possible it would be best to limit your game to a single 64k diskload to save yourself some sanity, but if that's not possible, then things are going to get more complex... You can clear an area of memory with the command below - it uses LDIR to copy zeros over an area: Cldir: ;Fill BC+1 Bytes fr...

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.

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...

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...

Thanks for all your help with this... I'm sure you're saving me weeks of work here - I'd be fumbling around for days figuring this stuff out!

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...

Update: 99%+ of hits coming from China! I've changed Clou...

'Sync Width' is the size of the sync pulse (the offscreen bits) You want to change Reg 1 - Hdisp This will change the width of the screen to 32 characters wide. ld c,&01 ; Load Register (&01 = H Disp) ld a,32 ; Load value (Set Speccy screen size of 32 chars) ld b,&bc out (c),c inc b out ...

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 ...
