DEMOS killing ZX-UNO?
DEMOS killing ZX-UNO?
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

Re: DEMOS killing ZX-UNO?
Is author of the post is not available, can I say?YERZMYEY escribió: list of demos that have problems working on ZX-UNO.
Pentagon mode works, but not exactly
Border in Pentagon one clock 1-t, in other models - 4-t.
the example of the Border
- 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

Re: DEMOS killing ZX-UNO?
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!!

Re: DEMOS killing ZX-UNO?
I think I know this one 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.azesmbog escribió:part of the main screen after drawing jumped up !! Perhaps the problem with incorrect timings processor?
EDIT: Yes, it was that. If you modify the BASIC loader and add
Código: Seleccionar todo
10 POKE 23739,111: PRINT AT 0,0;
I'll take a look at the ULA datapath to see if there is something I can do about it.

Re: DEMOS killing ZX-UNO?
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.

Re: DEMOS killing ZX-UNO?
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.

Re: DEMOS killing ZX-UNO?
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) -

http://www.pouet.net/prod.php?which=54207
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.

Re: DEMOS killing ZX-UNO?
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)

Re: DEMOS killing ZX-UNO?
It may. It is only that I'd like to do it altering the datapath as little as possible.YERZMYEY escribió:Ah, so this particular phenomenon rather will not get better?
