PC and Spectrum - a comparison Spectrum emulator: Unreal Speccy VS Z80 Stealth Emulator

PC and Spectrum


                              Golden Max

 Unreal Speccy VS Z80 Stealth Emulator


  Again, the theme of this section - emulators. At this time we 
will compare, contrast the two whales, two, in my opinion, the 
most powerful emulsion. Unreal Spectrum v0.18b2 and Stealth 
v0.500. Configuration companies, which were tested:

P200MMX/32Mb/video S3 Trio64V2 2Mb/sound
ES1698.


  Unreal Speccy we have (U), and
Stealth - (S).


  Let's start ...


            Interface (GUI)



  (U) Window, akin to Windows. In my
view, very comfortable.


  (S) standard, DOS. Nothing
excess, is also very convenient.


  Comment: Here the advantage goes to no one. All of the 
amateur. For example, I convenient to work in that way and in 
another, but I give preference to Unreal'u. Try to remain 
objective and therefore then draw - 0:0 ...



               Customize



  (U) is in this regard Unreal bit
ahead. Here at once from the interface can be
select the type of company, load the ROM,
adjust sound volume, etc.


  (S) Almost everything is set in the cfg-file. From the 
interface you can select Sound chip, on / off other zvukavuhi 
(SD, Covox).



  Comment: Yes, then walked US Stealth.
All that Stealth'e can customize
You can configure and Unreal'e, plus a bunch of
other settings. So, 1:0. Let's see what happens.


            The speed of the



  (U) Out of Control.


  (S) without brakes. However, when turn on the emulation of 
the GS at a low level here it all begins.



  Comment: In the US emulation GS at a low
level, there is therefore safe to say: the speed they are 
equal. With the advantage of one point is Unreal. 1:0. 


               Model ZX



  (U) ZX Spectrum128, Pentagon 128/1024,
Scorpion ZS 1024, Profi 1024, KAY256,
ATM 512.


  (S) ZX Spectrum 128, the Pentagon 128/512,
Ssorpion ZS 256 turbo +, Profi 1024, KAY
1024.


  Comment: As we can see, there is almost
all the same. Only US added ATM,
but in has Stealth'e KAY 1024. So that
give preference to none. We can say, US hit the bar gate 
Stealth'a. 1:0



           CPU Z80, INT



  (U) All right. I did not encounter bugs.


  (S) And here is not so good. A small difference in time with 
the Pentagon. 


  Comment: Stealth bit does not match
INT'om with the Pentagon. This is well illustrated by
Border effects. But the Real Audio Player
when the emulation of high-GS
level has not gone on any or the other. Although if you incl. 
emulation of the GS at a low level (Stealth) everything goes. 
And the US dates back to the big separation 2:0. 


         Supported Formats



  (U) SNA, Z80, TAP, TZX, WAV, VTX, TRD,
SCL, FDI


  (S) SNA, Z80, SLT, SP, PRG, SIT, TAP,
VOC, TRD, SCL, HDD

Comment: As you can see,
Stealth'e, the number of formats will be bigger. True, I can 
say one thing - used mainly TRD and SCL'om and

all others are very rare. And now
Stealth enters the bar, but on the scoreboard -
2:0.


                  Sound



  (U) Beeper, AY (choice of chip, stereo, and volume), Covox, 
SD, GS (Easy emulation).



  (S) Beeper, AY (choice of chip, stereo, and volume), Covox, 
SD, GS (Two-level emulation. Emulated the first time the second 
processor and memory !!!). 


  Comment: As in the US, and in Stealth
AY quality sound at an altitude. But with the GS
Unreal lost in the net. For the first time (in
Stealth'e) emulated processor and GS
his memory, the number which you can choose from 128 to 2048kb. 
However, for This requires complex are stronger than mine. And 
now the gap has narrowed to a minimum: 2:1.



         Emulated device



  (U) Gigascreen, Flash-color, cache 16kb,
CMOS, hardware multicolor, mouse.


  (S) Gigascreen, Flash-color, 512x192
(B / w the Pentagon), 512h240 (color Profi),
Controller hard drive KAY, cache
32kb, CMOS, modem, mouse.


  Comment: Once again Stealth ahead.
Unreal little behind, but who knows what
will be next? And again we have a draw - 2:2.


           Monitor (Debugger)



  (U) is present.


  (S) is present.


  Comment: Frankly, a debugger, I
never used, though I have about
their representation of the legendary STS'u.
So that the account remains the same - 2:2.


              Modes



  (U) A large bunch of filters.


  (S) is not deprived.


  Comment: To be honest once I reviewed them all, chose a more
optimal and there is not more climbing. Although
chunks on Unreal-e look much cool. A large number of filters.
At that meets Stealth video modes
100-150Hz! After an exchange of productive
blows through becomes 3:3. Everything
the above, I would like to add that
Stealth for many fastidious to Hardy.
And if you are on board, for example, fancy sound card, it does 
not necessarily You will hear a sound. Such garbage has been a

AlexGor-a, it has in my Live. On
my computer, I am having problems not encountered. Some, after 
reading all this, not agree with me. And again I repeat

- It works well on my
P200MMX/32Mb/video S3 Trio64V2 2Mb/sound
ES1698, and other companies listed above prog can work 
differently and the other performance. I also want to

asked not to be offended at me authors
I did not want someone to praise and whom to
then break off. I think I was completely objective. Maybe in 
the next fight will take another grand emulation - Real 
Spectrum Emulator. Until next time, on the pages (screens) ZX 
Time. 


  P.S. During the time of this writing,
were flooded neighbors living under me.
Forgot to turn off the water. Damn, and to the same
Wet socks:).

DWT>>> Well, no luck with the socks Max !:))))
