Hello, dear readers. Today I want to introduce
You with a couple-three recently appeared in our system
programmok.
BYTEMARE v2.0 COPYPROTECTION SYSTEM
(C), Alexander Korolev
First sistemka today - a very powerful protection against
unauthorized copying CDs - BYTEMARE V2.0 COPYPROTECTION SYSTEM,
written by Alexander Korolev, the city of Samara.
BYTEMARE v2.0 will only work on a 128-x machines with
versions of TR-DOS 5.03/5.04T.
Copy protection based on the principle of "floating
sectors", ie neodnoobrazno read. When you copy a conventional
Commander or potrekovymi copiers track containing necessary for
the proper operation of security information will be considered
incorrect and disc copy will not work.
At the time of this writing, the program author,
unfortunately, not knew about such copyist as McDONALD and
OMEGA, and therefore, if really want - can be removed from the
disk, protected BYTEMARE, quite a valid copy.
BYTEMARE has a unique opportunity cascading protection
files, ie one program may not be protected once and for all,
but several times in a row.
When you protect files BYTEMARE resident protection will
always be of different length, which virtually eliminates
writing anti-BYTEMARE!!!
Protection as a whole exceeds the possibilities of all known
MICROPROTECTOR and can be used in the quality of his
replacement. Xor ' Key in BYTEMARE much steeper than
MICROPROTECTOR'e.
If you want to defend the program from its backup, then
either write protect themselves (that is preferable) or Use
BYTEMARE. Good luck!
HRUM v3.5 (48/128)
(C) Dmitry Pyankov
Compressor
Relatively old (January 1997), the compressor, but that
surprisingly, very steep at the moment! Yes, it is the steepest
since shakes HRUM better than PCD v6.2. And if we talk
komressii about speed, then there HRUM is a leader.
Once it becomes clear that the author of this wonderful and
convenient in the bend approached it very professionally.
Now some characteristics:
√ maximum length of 49,033 b kompressiruemogo file. !
√ full length of the decompressor 150 used.;
√ compression speed 1 kb / s (faster than LPC)!!!
√ decompression speed 33 kb / s!
√ Ability to work with included IM2 interrupt, but here
There is one condition: the interrupt handler must be
his stack, that is something like this:
di
ld (old_sp +1), sp
ld sp, new_sp
push af, bc, de, ...
...
pop ..., de, bc, af
old_sp ld sp, 0
ei
ret
And the speed of compression: it is 1.5-12 times higher
than any currently existing compressors.
PCD v6.2
(C) KSA SOFTWARE 1996
Improved by VEKA / CPU 1997
Compressor
PCD v6.2 now occupies second place among the existing
compressors. He is slightly inferior to HRUM'u the degree of
compression, but Still zasluzhivet to use it. This was made
possible thanks to correct glitches that PCD was just stuffed.
In version 6.2 the probability of freezes when decompressing
(due to zoom unpacked part of the block on all unopened) has
decreased significantly.
Compression speed leaves much to be desired, but the
correction smooths out the glitches in this deficiency.
In the end, I would like to thank VEK'u for his work,
through which everyone, without fear can enjoy a fairly good
compressor.
P.S. Speaking of copy protection: we now have a
MEGAPROTECTOR, which is written in help'e, not copies
Xia McDONALD'om v2.0/2.7, a well OMEGA Copy v1.30. But in
a system Lou obscure reasons we protect these files after
protect'om
completely otkazyvyutsya run. Climb to secure data
nym protect'om prog, I found xor'ku who does not
rasksorivaet! We certainly understand that this is just a
beta
release, but still could do so after prog
protection even worked ...
And another thing: saying that at this point is self HRUM
mym fast compressor, I have not seen the Turbo-LZ, so that
quite possible that the Turbo-LZ by SIMM / PhF will be
faster than
HRUM. We can only wait for us of this program.
Overview sistemok to you by Alexander (Paracels).
