DEMOS killing ZX-UNO?

Mensajepor YERZMYEY » 30 Jul 2016, 17:49

Well, not exactly killing, this time (it has nothing to do with the effect I discovered in the games' case) but there is a number of demos that don't work properly.
I was wondering if You'd be interested in such a list. I could make for You a list of demos that have problems working on ZX-UNO.
If You intend to develop the cores, then maybe You'd like to know what can be fixed.

If so - let me know, pls. I could put the titles (and links) here.

Regards,
Y

Is author of the post is not available, can I say?
Pentagon mode works, but not exactly
Border in Pentagon one clock 1-t, in other models - 4-t.
the example of the Border

Imagen - real
Border Create - https://zxaaa.net/view_demo.php?id=7367
second trouble - ibid
part of the main screen after drawing jumped up !! Perhaps the problem with incorrect timings processor?

Check the program for real ZX-Uno please :)

I am aware of the border issue. Pentagon timings are not fully implemented, as the border 1T state change would need a redesign of the ULA data path. I will test them to see if there is something I can do to improve the visuals a bit.

Thank you very much!!

I think I know this one :D It's the loading process, that puts the name of the file to load on screen, making it to scroll. Will test if it is that.

EDIT: Yes, it was that. If you modify the BASIC loader and add

Código: Seleccionar todo

10 POKE 23739,111: PRINT AT 0,0;

There is no more screen jumping. The border issue is not as easy to fix, I'm afraid :D

I'll take a look at the ULA datapath to see if there is something I can do about it.

Ah, so this particular phenomenon rather will not get better?
I noticed the same thing, although in another demo - "RAGE": everything works, and the final part - not.

Will look for stuff when I have some time.

Where can I get this demo?

And this one?

This is the best I can go without modifying the ULA datapath, only controller is modified to accept a new border colour on every pixel clock, but there are delays in the datapath that must be bypassed, so this is not perfect.

Hmmm, strange. Seems like they come from the "3BM openair" party
http://www.pouet.net/party.php?which=1575&when=2015
but I cannot see the border demos on the screenshots.

Maybe You could check out those instead (considering their descriptions) -

Tomorrow I have a hard day too but maybe since Wednesday, or at least in weekend I would have some time to sit over it.

It's not exactly a demo, likely drawing on Border :))
but for the timing of the Pentagon. For timings 48 - 128 my crafts
probably seen everything?
In the emulator, you can see the correct results.
Drawings on the Border is easy) but for a long time)

It may. It is only that I'd like to do it altering the datapath as little as possible.

I think that particular demo works now with the lattest additions to the core :)
