Hello, max_iwamoto
I wrote here www.amiga.org.ru/article.php?sid=7720, we are waiting for a reaction.
Hello, All
Enjoy!

C; Cashum is just the opposite. I don't remember all the details, but everything
commands come from even addresses, the location of the processor command emulation code is from
addresses divisible by 256, etc.
Although they were sharpened for 68030, they might have forgotten to correct it for 68040 (or vice versa).
So in one way, Dr. Titus is right. But it was already there anyway
optimization optimization. The emulation code itself was debugged very well (according to
tacts), all commands are tested + all undocumented commands too
included.

It is this 256-byte alignment that harms them. Cache on 030, for example, 256
byte, and all commands located at addresses, for example, 0x0000, 0x0100, 0x0200 and
etc. will end up in the same cache location, thereby overloading each other. On 040
not much better.
Undocumented commands (flags) are also implemented partially.
But in general, I don’t want to swear at the emulsion, because... I used it myself: v2_blush:
Hello, max_iwamoto
max> You need to dig in the place where the ROM is patched.
There, the ROM is patched immediately after loading. And, in general, for what purpose?
Hello Titus
Tit> Undocumented commands (flags) are also implemented partially.
Wse komandy emulatsya through tablicy. Wse flagi 100% original Z80... Privedi
primer? what is not 100% emuliruet flagi?
Hello Titus
Tit> Well, not to mention MEMPTR, I remember offhand that add hl,dd doesn’t have everything
Tit> flags were emulated (or it was adc, I don’t remember)
Yes, can byt' ty i praw. add ili adc (a can get i obe) zanimali mnogo taktow i
tablica ne wlazila. No eto wsego 1-2 komandy. We need to look at it. I've become selfish
interesting.
Hello, max_iwamoto
but I wonder if the emulation of LD A,R is taken into account
sometimes this command incorrectly sets the P/V bit, and secondly, what is it?
happens at the moment the interrupt arrives, and not whenever...
details in Roshchin's article:
http://ivr.webzone.ru/articles/ldar_new/index.htm
Hello, Daniel
dan> but I wonder if the emulation of LD A,R is taken into account
LD A,R 100%. Ya wcera smotrel sources. Tam na protiv kagdoj komandy stoit ++
or +N. Ya ne pomnu chto eto oznachaet, no pomoemu ++ ya pomechal 100%
emulayacii komandy i wseh flagow.
Hello Titus
if you run this from TR-DOS, the CBSpeccy 0.25 emulator will freeze: v2_cry;
http://crank79.narod.ru/A1200_reboot.zip;
I would like to see a new working version of the emulator on winUAE

Hello Crank79
Cra> I would like to see a new working version of the emulator on winUAE
Why go to Kyiv through Magadan? CBSpeccy is a project in itself, not emulating
fully specced (it was not required of him, he was required to fit into
performance 68030), and it’s unlikely that anyone will add to it.
And to work on WinUAE you need, at a minimum, a correctly emulated MMU and not
just...
Hello, max_iwamoto
max> A esli podstawit' drugie roms?
haven't tried it
Hello, goodboy
I also couldn’t download it from Internet Explorer at first. took off
error window, I clicked the green “Go” button and the file was downloaded. Try it
several times, this file is there.
Hello, Sergey
disk B is damaged if you substitute TAP/TZX, the tape image is placed on the disk image.
Hello, max_iwamoto
max> A esli podstawit' drugie roms?
Regarding other novels, I was happy early:
Through the "NeOS" ROM I successfully started TRDOS-128 and ProTracker, which booted
was registered. However, when I tried to launch the game "Run away2", the emulsion hung
firmly at the stage of starting redrawing
TRDOS screensavers.
"Inferno Guide-6" launched normally, but after the end of the intro it froze.
What to do?
What’s interesting is that on 030 everything goes without problems.
And one more thing:
1. Does not start under OS 3.9 at all. :(
2. The contents of disk "B" are corrupted.
Hello Crank79

I checked v0.25b of the Blizzard 1230-IV axel, nothing happened to the Amiga

I don't know about OS3.9, but the fact that TZX corrupts drive B is normal. It was
It was done temporarily, and then they never removed it or released a new version.

strange; I launched it with the same axel - the Amiga froze, log in using F10
It didn’t work, I had to reboot the system.

So it's not CBSpeccy!
Hello, max_iwamoto
By the way, due to its very free handling of the system, CBSpeccy is quite
buggy thing. I have repeatedly observed PFS crashing when using the emulator :-)
Hello Titus
My clock often reset to zero, it seems also because of the emulsion.
Hello, goodboy
here is the emulator kit I used
http://crank79.narod.ru/CBSpeccy025_Crank79.zip
Hello Crank79
I checked, everything seems to be fine, maybe it’s the NewMode program, now I have Monica
VGA, screen in DBLPAL:LowRes emulator
the easiest option is to check on an empty system, without any add-ons
Hello Crank79
Cra> strange, I launched it with the same axel - the Amiga froze, into the system by
Cra> F10 could not be exited, I had to reboot the system.
That's right - it's strange that it didn't start. worked for me on 030
wonderful. In my opinion, I even used it on the 603e with 040 on board without any problems...
Hello, acidrain
The emulator worked, but sometimes it froze, I used this archive and the emulator
naturally worked.
there were cases - I searched FRZ, then very quickly pressed Start, the file was still complete
I didn’t have time to download, but the emulator had already started)), in the end I see a sad picture
- black screen with a floppy disk in the corner. You can’t return to the system, you need to reboot
Hello Crank79
Cra> needs to be rebooted
Try the button combination - RA-M and no need to reboot. I think even in this
These buttons just work. you just need to know a little more about the Amiga ;)))
Hello, acidrain
aci> Try the button combination - RA-M and no need to reboot. I think even

If the emulator turns off the system completely, then NO system buttons will work
will
