Sadly no, with Mode 13 it wouldn't work since it doesn't use ld-swap-ld for palettizing, but a different technique. But I contrived a method how it is possible to cram the ld-swap-ld technique for palettizing in 6 cycles per pixel, and on that, this blitter would work! (See the linked post above) Fo...

It is still a long way to make it sort of "official"! I didn't even fully decided on the interface yet. To summarize, the following key elements are missing, need further work, or I plan them in: Scrolling assistance functions to have an user-friendly support for it with sprites. I already...

I took an another look on this 6cy / pixel code to see whether it would be possible to get 192 ROM tiles out of it. There is a catch, a double-catch at that, but it seems doable! Catch one is that you will get a fixed 2K RAM area for RAM tiles, which you can place at any 256 byte boundary. This come...

Yes, I meant compared to the good old breadbin, you have no sprites! If anyone is really interested, I might build these modes up later, but right now you can see I am a bit swamped by video mode ideas on their way of realization :) . I think X scrolling (Y is always rather easy...) is possible afte...

Interesting ideas! I didn't yet look in what happens when one calls update_sound, only digging in it when I noticed how it also uses the T flag (got some nasty bug from that, its not the register usage which is the problem, rather the occasional lack of its correct documentation). I saw there is a l...

Mode 74 now has sprites!! Long tedious work it was, but the bulk of it is done! :) The Mode74 code is up on GitHub: https://github.com/Jubatian/uzebox/tree/mode74 I did a small tech-demo for it to test all that code, you should see something like this if you start / compile (good luck) the attached ...

I was just experimenting with partial code tile techniques (similar to CunningFellow's Tempest engine) to see what I can get out of them. And it seems like there is a quite epic mode hidden within! I post its render loop and properties, might inspire someone to go on with it. Maybe later even me, bu...

Thanks, I imagined it is something along these lines. Yes, I understand if I needed two sectors, then I would have to send another CMD17, wait, and only then would anything happen. My thoughts on use cases would be that when I want to fill up VRAM or fetch a larger set of RAM tiles etc, that's betwe...

I will also likely use it, at least once I finish up more or less with my video mode experiments (still working on sprites). What I will try to do though is messing around with the video mode itself so it can load an arbitrary part of an SD sector, so it would be possible to receive bytes from there...

Huh, that's an epic little piece of code there! Nice use of the capability to do anything for getting pixels on screen! I guess you already spotted it, just mentioning: I think you rather wanted to calculate the color in r25, not r24 there (as that register was loaded with the wall color). Not only ...
