Protect - Protect and antizaschita programs.

(C) LELIK / Diamond software (original idea by SERG)


                 P R O T E C T and D E P R O T E C T.

For opening protection required at least three things:

First, enough free time;

Second, the appropriate protection of iron;

Oh, and the third, his head on his shoulders.

At the expense of time hacking, Screw best protection that I
cracked, have been hacked within a few days (but not as not
weeks or months, as they say, some comrades).
Now more details about some of the chips, which complicate
opening protection: active work with the stack, use
undocumented commands, grout the entire memory, support DOSa,
when decoding, etc. not really complicate the process of 
cracking, but with the appropriate hardware estestvenno.Esli 
you want your program really long time hacking (I mean getting

pirated copies of games), then do not be lazy in the game 
(between levels at Dozagruzka etc. ) To make control

verify the operation of defense mechanisms when the game starts 
and According to the data to change the game situation is not

favor of playing, or continue the game without interference 
(but do not advise you hard, "hang" a wheelbarrow, or reset by 
RST # 0, etc. because these things are easy to catch in the 
program). This the most profitable way to protect your games 
since his promotion HACKERu have to deal with the logic of the 
program, which can hold dozens or even hundreds of kilobytes,

of course it does take time (and small). Also do not forget
about linking the game to disk (non-standard format, unreadable 
sector tracks are very spoiled nerves copyist, as well as those 
who use them uses). But naturally, these methods will only 
prolong the time of breaking (Although the author is right, so 
for some time nebylo pirated versions), but of course sooner or 
later cracked all!

If you want to learn more about existing methods of protection 
and breaking it, the more break other people's prog:)
