Emulators - Review Spectrum emulator.

               Emulators



 Today, many, perhaps, there is a desire at least for some time 
to throw the "Quake" away and play in

something old and painfully familiar.
Come on, think with what platform begins your introduction to 
the wonderful world of computers? And many would say: with 
ZX-Spectrum.  With the help of emulators, Spectrum, Review

which is devoted to this article, I propose
you plunge into the past and remember your
Computer "childhood." Of course, after PC
you do not even look at the Spectrum
strategy or simulators, but the arcade on
Spectrum has always been good. Personally, I
gladly spent time with some
old games after a long hiatus.
 The first emulator "Spectrum" I saw years
six years ago, but the speed of his work on
286-m processor and four-color CGA instead
Spectrum of sixteen is not very happy. Recently I decided to 
check how well situation with emulators for Spectrum online. 
And what do you think? It turned out the people wrote and wrote 
such vengeance emulators! And now in the court in 1998, and 
Performance PC to emulate 8-bit computers are more than enough. 
The Internet kept tens of thousands of toys and Spectrum 
programs. It turns out Spectrum that is almost completely 
"moved" to Internet.

 I fished from the web about a dozen emulators and
I hasten to share the results. But first
should say a few words about file formats, which are used by 
these programs. All files can be divided into two type: the 
so-called tapes, and snapshots.  The first is a virtual kind of 
tapes used in ZX-Spectrum. Emulators can "boot"

with these files. As you might imagine, the download in this 
case is much faster than real tape loading. There are several 
basic formats of this type.  . Tap-easiest, supported by many 
software emulation (similar Format:. ltp,. spc); keeps only 
files and their titles - sequentially, as in

tape. If the recorded programs are loaded outside the box of 
this size would have to give. But it can be stored Programs 
using podgruzku tape (Eg, multi-level games).

 . Voc-well-known storage format
sounds. The files contain the sound from the tape, allowing you 
to store programs custom boot (though quite

Wasteful this business, I tell you) are most often used when 
transferring programs from tape to computer.  . Tzx-roughly the 
same as that. Voc, but storage accounted particular recording

magnetic tape, so that files of this format takes up less space.
 To download the software from these files must be in BASIC-48 
on the keyboard to type LOAD "" or choose [Tara Loader] menu 
Spectrum-128 and "run" tape with the emulator. Now consider the 
second family of formats.

 Snapshot (z80,. Sna,. Snp,. Prg) - file
Spectrum memory contents and registers. In this case, 
completely eliminating the need for loading programs from tape 
and Disk (virtual or real). With these files, you can store 
programs with non-standard load after

Once you are able to load them into memory
emulator, and you can save the game,
you set a new record in the results table.
 In addition, there are files of floppy TR-DOS (. Trd,. Dsk,. 
Fdi) and mikrodrayva files (. Mdr), but they are also rarely 
used. Often you will fall and. Scr-files containing the image 
of memory "Spectrum" (a picture).  Information on the 
possibilities of programs shown in the table.  Now a few words 
about each of them. To avoid confusion (as the names are 
similar), I will indicate the names of the creators of the 
programs (in parentheses) and the version number (probably when 
you read this line, the network has more than fresh).

 The first was found Z-80 emulator v3.03 (G.
A. Lunter). It was he who inspired me to
further exploration, as in this program, I finally saw all 
sixteen colors that are supported by the Spectrum. But there 
was one snag: it's shareware-program, and

for registration need to put $ 23,
otherwise, certain functions will not work. Registratsiyadelo, 
of course, is good, but There are many totally free

emulators are not inferior to that as possible.
 JPP v14/12/92 (A. Gulbrandsen) and Irish
(K. Phair) - known emulators, but
rather outdated, little support
file formats and emulate only the earliest
Model Spectrum. I mention them only then,
so you do not spend time on them.
 Nuclear ZX Spectrum v3. 69 (R. Garabik, L.
Salanci) - a good emulator, but lack of support for PC-joystick 
and sound maps is disappointing.

 Warajevo v 1. 50 (Z. Juric, S. Ribic) -
roughly the same as the previous
emulator, but with support for PC-joystick
database programs. Have already downloaded this
version, I later discovered that the web is
and a later version (v2.00), supporting tzx-format and whatnot. 
This emulator is quite good and continues to evolve;

so recommend. The authors have started to create a program in 
Sarajevo, when there was war. In doc-file, you can read as

arduous work of the programmer in the field, when there is no 
electricity and other for a peaceful life.

 The next three emulator created by our
Compatriots (loud "Hurrah !!!").
 UKW v 1.2 (?). The program has a rather
a powerful debugger.
 ZX-Emulator v0.30b - apparently the author of this
Program VS Yudin is a great expert in the field of video 
programming, as this emulator better than all of the I have 
seen celebrating, Xia with effects on curbs and other 
associated with the frequency lines and personnel. Excellent 
emulation and sound. Disadvantages: low frame rates

(About 50 Hz as the TV) and the lack of support for the 
joystick.  ZX-Spectrum v3.04b (H. Shalaev) - good

choice for enthusiasts to experiment.
The program provides a wide choice of
settings and allows you to create and connect the extension, eg
to download files of any format. K
Unfortunately, through the sound card output
only the sound of a synthesizer sound speaker output from the 
PC-Speaker.  ZX-32v1.03b (V. Kapartzianis) - the only one of 
all the emulators for Windows 95. I note of the shortcomings of 
distortion, and the fact that when working in full screen mode 
appears interlaced.  X-12V v0.8 (J. MsKeu) - this emulator I

I use most often. Emulation, including on Windows, is 
excellent, the program supports all the formats are well c 
joystick works, good prints sound. Of course, there are many 
more emulators for different platforms. Perhaps

I found the most perfect and powerful of
them, but if so, then here you are, and maps
in hand.
