Hi all! And a Happy New Year! Today I have a very good mood,
confident that you, too. Therefore I will depart from its
customary roles, "grumpy uncle, always dissatisfied with all
USERami, programmers, writers, destiny, life ...
° ° ° °
Finally! Hooray! My quest (rubrics "WANTED" and "Mosaic")
failed! So far I have forwarded only two fugitives
game. The first - "2112 A.D." shook me Yuri Vasin, known to you
on articles in the "stuck?", the second - "KAT TRAP" sent
Andrew ... (On the joys, I forgot to ask how the name and phone
number). Despite the lack of cover images, games fully
functional. But because they were not interested in me, I'm
willing to give them to anyone who wants to make a normal
version.

Another happy (I hope) news for you. Coming soon restored
version of the game "CAPTAIN BLOOD" with all podzagruzkami. I
think this game should not be. Those interested can learn about
it from the 15 th issue of the journal "SPECTROFON". I handled
the game, INTRODUCTION wrote KSA SOFTWARE. Game performance on
computers with memory 48k and 128k. Implemented two independent
loading conditions on the disk, and users can enjoy a 128k car
AY-music written specially for this game KSA SOFTWARE, some
good special effects (written by me, of course) and also enjoy,
in addition to shipments to a floppy, two shipments of memory
and the possibility of restarting the game in memory (and then
understand why it is needed). Work on the game is almost over,
but still makes it possible for postponed New Year (you know
why ...). Edition of the game is scheduled at the very
beginning of the year, most likely, we will have time to finish
it for release "SPECTROFON" N 17, where it appears. Freaky
game, honestly! So far, it has no man has gone!

NIKO SOFT (BBS NEWS) threw me the other day a bunch of
numbers "ZX-Revue" and "ZX-FORUM". Frankly, I've long these
logs are not read it, because after that panky, what's
published in early 90, I have developed aversion to this
edition. It turns out, in vain. Now, despite the support of
dubious hardware and software developments (... had promised
the same do not swear ... see, I was not correct), there are
many interesting things. Articles devoted adventyurnym and
role-playing games have been written exclusively professional!
Expert analyzes games - the best I have ever seen (although, in
the "ON-LINE" no worse, if not better!). Notes addressed to
novice programmers can indeed help them (yeah let's be honest,
I myself, at one time, a lot of them picked up) and, although
an experienced coder to look for them there is almost nothing,
so I dug into them:
Now very common ways to refer to the drive through
"Direct programming" VG93. Through # 3D13 virtually nobody
works. I'm not talking about the TURBO-LOADERah who have
already become a standard device. But almost all such
procedures apply to the floppy drive A. And where there is
realized an appeal to any drive, such nakrucheno ... Meanwhile,
all ingenious is simple. Try to explain it so that I understood
not only by those who even fills in the text of articles TASMe,
but those who use procedures, pulled out of other people's boot.
So, in any such procedure is a periodic setting of the disc
by zasylaniya to register # FF controller number # 2C and # 3C.
So, if these numbers are, and # 2D # 3D, then the appeal will
to drive B! In other words, bits 1 and 0, the above constants
are responsible for the number of the drive. When it comes to
boot for games, it is enough when you first start to initialize
the constants with respect to cell # 5D16, established
TR-DOSom.
Yes ... I looked at the previous paragraph, and realized
that I hardly ever anything I can not explain the hacker. Well,
okay, smart enough.
I'll be back, perhaps to the "ZX-REVIEW." Can me someone say
what kind of team: INK HL, pictured on the cover of magazines
for 1995?

Finally, I want to say hello to DrLongman'u! DLNews - really
interesnoya newspaper. But now it goes about it, and file
"IBMgraph", issued by him. I would like to share my information
about the format of PCX. I want to share in the pages of
"ON-LINE", because I think it will be too many are interested.
Unfortunately, I only know about black and white PCX ... As
already understood by those who dug it - the image is stored in
the compressed form. Header has a length of # 80 bytes. There
is nothing interesting, except # 42 bytes, which stores the
string length in bayytah. Discard the header and checks the
first byte. If 6 and 7 bits set, then reset them and get the
number of repeat the next byte. If the bits are reset, then
just send the byte and move to the next. Naturally, when number
of bytes written exceeds the length of the string, go to line
down.
In fairness, I note that this information podcherpnul in
one of the Kharkov demonstrations and have not tested it
myself, so I it seems logical that a single byte is considered
not only when 6 and 7 bits are reset, but if not set at least
one of these bits. So, please: DrLongman, when tested and get
results, call me, if not difficult.
