when the source? ))

As always, the source of this core is in the repository. This version I'm showing to you will be commited to it in a few minutes.

Hi mcleod_ideafix!
Can you provide the TAP file for the upgrade, please?
Well... I´ve upgraded the SMS core with a TAP file and it worked well.
Same as with the ZX81.
So... the ZX Spectrum must work, right?

Thanks.

ZX81? We have no ZX81 core :O Don't you mean Jupiter ACE core?

Turrican escribió:So... the ZX Spectrum must work, right?

It should. Let me do a few more tests before committing it to the repo
What BIOS version do you have?

Here you have it: the last Spectrum core, T22-01082016.
As you already know, for enabling Pentagon timings, you have to use the zxunocfg utility, this way:
and then, load your favourite prod. Timings are in effect until the next master reset or power cycle.

Oh, sorry. It´s not a real ZX81 core.
It´s this: viewtopic.php?f=37&t=426
I have the 0.42 BIOS version.
If you have a TAP file to update de BIOS, It will be great!

PS: wich is the best way to make an update? A file in SD card or the TAP file?
I have updated using TAP files and it worked well!

Thanks!

Almost perfect !!!

The discrepancy between the border and the screen only 1 pixel. This is normal
Remove possible, but not easy
In another project, i changed the clock phase to delay by 1/2 cycle

I uploaded here the .TAP and the .ZX1 (for upgrade by SD) of the firmware V 0.47. The two files are in the .ZIP file

For BIOSes prior to 0.46, tape is better
For BIOS 0.46 and later, SD works great, as well as tape.

Here you have BIOS 0.46 in TAP format

As I commented to you, this is the far I can go WITHOUT changing the ULA datapath. I just need some more time to re-design that datapath so the border gets updated to the screen as soon port #FE is updated, and not a single cycle later. But for the time being, I think it is a huge improvement over the previous core, isn't it?

I say -Almost perfect !!!
I check out several demo - other problems
Upd
nosignal - must be colored bars.
Again exotic switched mode ??

Thanks for all!
