Testing emulators using z80test-1.0. Quick results

[PeterJ]

I missed this first time round [mention]druellan[/mention]. Excellent work!

[PeterJ]

Do you have time to test it on ZXBaremulator [mention]Pegaz[/mention]?

[Pegaz]

Thanks for adding the link @Pegaz

I deleted my post asking for the link, and your post saying you had added it. Thank you.

Its probably because nobody else had heard of it. Thanks for mentioning it. They also have a version build into Visual Studio which looks neat!

Has anyone tried it?

I think they are from different authors.
The author of SpecIde is Marta Sevillano Mancilla.
As far as I can see, the author of this second emulator is Istvan Novak.

Do you have time to test it on ZXBaremulator [mention]Pegaz[/mention]?

Sure, no problem, Baremulator goes through all the tests, but I think zx81 already mentioned it...

[PeterJ]

Interesting, it's all under the same GitHub subdomain. Assume they are working together as a group. All good stuff.

Great that ZXBaremulator passes all tests as well as the latest Fuse.

[Pegaz]

In fact, [mention]MonkZy[/mention] has already tested the Baremulator, here:

I've tried SpecIde in the past, and it works well, but its accuracy comes at a price. On my machine, it uses a lot of CPU and runs too slowly to be really usable. I don't know if that aspect has been improved since then, but maybe it runs better on other people's computers anyway.

[PeterJ]

A rather left field one for you, with an interesting frame.

ZXSpectrum4

The free version is very limited (The buttons don't work, apart from keyboard). You have to drag and drop files onto the emulator, but the results are good.

[PeterJ]

I also thought I would try the latest version of ZEsarUX from [mention]chernandezba[/mention]. One of my favourites!
The results are the same as with the earlier version tested.

No$zx
2 of 152 failed. Link below.



ep128emu (Enterprise / Amstrad and ZX emulator from 2010)
5 of 152 failed. Link below.



The Windows version of RealSpec 0.97.26 gave me 20 fails out of 152. 1 more than the DOS version.



Found this whilst searching this morning. Its a bit out of date, but still some good stuff included:

Finally, unbiased as we are here, I tested Spud 0.252 and it did very well and passed all tests:



I like the link to infoseek. Just a pity no software to download. The same thing could be done with the OpenAPI to ZXDB as others have done successfully.

Last few versions I tried, work just fine on my old dual core laptop in full screen mode.
If you've only tested in windowed mode, it's still crawling.
Fortunately, full screen mode is the only thing that matters to me, and it works really well there.
I also tested 50hz sync via the hdmi port on the TV and it is great, I would say perfect.
Also, the emulator is rock solid stable, but until it has some sort of GUI, I doubt it will reach a larger user base.
btw, it's really refreshing that after many years, we've got a female author, an extremely talented programer, like we may not have had in the Spectrum scene, since Veronica Megler.

Is there any test, that we can run, to determine if the floating bus is correctly implemented ?

I have not tried it [mention]RMartins[/mention], but there is a test file here:

Edit - Just loaded it up:



Have I found something not in ZXDB [mention]Einar Saukas[/mention]?

looks like this one needs strict 48k emulation, not even the 128k in 48k mode

The first ulatest3 was for 48k only. Probably, the Smith's version derives from it. Jan published updated versions from his tests, but I can't find it to download now.

There's also a test for the well known "snow effect".

Just a few emulators can run it properly, SpecEmu and SpecIde for now, but of course I didnt test them all...
Here's what it looks like on a real 48k Spectrum, as a reference:

Can you share home page or some link for more details about this emulator?

[polomint]

Wow, that one looks like it could be very cool, eventually

[Pegaz]

Still waiting for the link to that mysterious emulator.

Your wait is over...

https://github.com/mikedaley/SpectREM

It's not been touched for two years though. It's Apple MacOS only.

If users are posting about unusual Emulators please include a hyperlink to the project page. Thank you.

There is also the CPP version of the above at https://github.com/mikedaley/SpectREMCPP

[PeterJ]

Excellent [mention]polomint[/mention] . Do you need to run compile it with Visual Studio or similar? I can't see a pre-built binary.

[Pegaz]

I don't have a Mac, but thanks anyway.
Windows build would be very welcome of course...

btw, Patrik Rak has opened a github page dedicated to his z80test programs so anyone can find and use them to check the emulator's accuracy.
