Totally agree! These videos are a great reference!!! :D Everything is bad and very bad :) There is a new, final, series of 7 tests. Z64K correctly shows only one test, the rest fail. The ES.pectrum emulator shows correctly the first 5 tests, the last 2 - fail. There is a video, but I would like bet...

Someone always knows, but writing and telling is usually too lazy.;) To begin with, we decide for which car we are going to build a border. There are three main candidates - the classics zx48, zx128 and Pentagon. Note that building a border for the Pentagon is more interesting, simpler and more beau...

Vertical: 50-76 Hz The Pentagon has a frame rate of 48-49 Hz, not all monitors show even 50 Hz. So just try. There is even a special utility for checking monitors. Even monitors of the same model and lineup perform differently. I have several monitors Samsung SyncMaster 940N - so they work after on...

So far, the most accurate emulation, the video is fresh here

On your emulator I'm debugging snow tests)

Not guessing! The winner is a well-unknown emulator written in JAVA (Or is it JavaScript?))

The picture is exactly the same in both tests, and in one more

Fine!!! Excellent video quality and the right angle !!! btw, I looked at the old snow test and tried to compare with the SpecEmu. It looks like pattern isn't 100% identical... This test demonstration was carried out just in order to clearly see and notice the difference between the real ZX48 and emu...

And one more emulator, this time for Linux and MacOS

In this moment Telegram group of ZX-Uno There is still no telegram yet. It's not time yet% :) I hope these days, I can test your new test core and this snow test again. I will look forward to it !! And in order not to get up twice - check and make a video modifications of this test. https://drive.g...

Otherwise, I think that fix for zx-uno is necessary after all... Please check if it doesn't bother you. And another request. I understand this is your video? https://youtu.be/Ix9Wy2jhDwI Another request - is it possible to make a video of this test again, but for a longer time and with good quality...

https://drive.google.com/file/d/1iHuDDFp8gb3g2CFc52I-At4h2oIu3Bba/view?usp=sharing Just check it yourself. I have not tested on ZXUNO. Added two lines and compiled. But all the same, since the joysticks cannot be disabled in the BIOS, but only changed, you must also use Bob's browser and disable bo...

the game is really incomprehensible and this problem is not worth a damn. With the Kempston joystick, everything is fine :) Connect the joy - and you will have joy :) Well, if we proceed from 100% compatibility - then yes, as a test of the stupidity of the programmers of this game - then it's ok :) ...

@azesmbog of course can turn off the hell of a Kempston joystick, but give it a "wrong" file that does not work correctly. For check.

then you also need to add Z64K


ZXSEC fixed

Watson, this is elementary !! (c)

In principle, a pretty clear explanation. about TR-DOS - there are users who would like to run real floppies. (I'm not one of them :)) I was more interested in musical possibilities. For myself, I have added SAA1099 already. TSFM, of course, I can also try to add, but it is less interesting to me, i...

Maybe that could help? Yes, it did help. I didn't know about such an option, and I can't imagine why it is needed, and why it was disabled by default. But - thanks :) This work of mine revealed a slightly different behavior from other emulators of some rarely used bits of the #FE port in the last t...

Of the major changes - the TR-DOS regime in the Pentagon is seriously broken again. Somehow I didn’t launch my crafts before, but then I tried it and got upset. in specemu-3.1.b080220 - ok. in version specemu-3.1.b201120 - it's already bad :( in version specemu-3.1.b160821 - everything is just as ba...

I was checking the latest version of the emulator and came across a border picture that I drew last year. https://s.micp.ru/BlYU2.png Pentagon timings https://drive.google.com/file/d/1BkZcoFjVeD9L4KBaJIN0aEE4wmDpMQ1J/view?usp=sharing And this I "plagiarized" a little. I really liked the fo...

Now the labels are parsed correctly.
These operands are missing:
INC LX
DEC LX
INC HX
DEC HX
These are all halves of index registers.
It is necessary that the authors of the assembler write a descriptor for them))

It's more significant, better and more interesting. From wishes - I do not know how much better it will be, but I would like the left and right parts to be synchronized when dragging the "elevator" (?) Between them. Of the obvious bugs, there are no operands: LD HX, B LD HX, C LD HX, D LD ...

Did a clean install
1. Downloaded CSpect2_14_03
2. I downloaded cspect-next-2gb.zip and unpacked it into a folder with CSpect
3. Added a batch file from the previous version to the same folder. Voila!

I have it loaded from a batch file, the result is on the right.


With all due respect to Caesar - the interface of his emulator is "For the Strong in Spirit" !!! I use it in the most extreme cases)) but they happen sometimes, yes

I am also not fond of contended memory, I like the architecture of the Pentagon, but nevertheless it is sometimes useful for myself to figure out how it works, especially in relation to the screen and the border. There are still quite a few users of the classic zx48 \ 128 :) Well, when drawing on a ...

It is of course encouraging that the utility is developing. But... In my example, there were only two long lines. And when there are 320 such lines ?? Choose the beginning and the end every time ?? Here's an example a little more complicated :) The picture is big, let it be under the spoiler https:/...

I tried the utility. For me, this is a pretty useless utility :( Parses all instructions into one line, and shows the ticks. I'm more interested in if it would parse and count in one line, in which there are several instructions at once. An example on two lines: NOP: OUT (C), A: OUT (C), A: OUT (C),...
