bugs Chips and firmware ROM and Dallas for win slot machines Mega Jack. Bug on doubling or extradition of major characters
Bugs in the firmware gaming machine Mega Jack
On this website bugavtomat.ru I will try to tell them about bugs in the firmware slot machines Mega Jack, and how they win.
For a start, a little bit about what the math program .. According to the developers (Casino Technology - manufacturers of the software) is implemented in a program called a statistical algorithm. It is understood that each of the combinations following is not a result of the behavior of the board in the previous period. Percentage who remains the owner, achieved through the planned rate of loss of any character (character combinations). For example, the mechanical Roulette - the casino profits through the loss of the ball on the ZERO (in the classics - the player is not able to put on the field). how to win at slot machine? MegaJack useless reset even if he lost a lot of money. He will act independently of meter readings and the last payment. Just does not make sense "to win back the" Mega Jack slot machine before installing the object ("that would not be betrayed"). It is much cheaper (and, incidentally, takes less time) to sprinkle holy water on board (before switching to dry out) - the same result.
In most programs, released before the year 2000, used "funded" system. The prize fund (the maximum amount that the program may issue at the moment) is stored as a certain percentage of the money lost by players. This scheme is more predictable, but less interesting for the player to normal (ie not the one who knew the amount of the lost device gets his win). Thus, the gaming machine Mega Jack - more unpredictable program that can go into the "minus", and these situations are less conspicuous than in the case of cumulative systems.
Math Mega Jack closed to the public, personally unknown to me, so all of the above - my guess, though confirmed by operating experience.
Now, how introduced bugs or bazhnye firmware in slot machines MegaJack.
The real way to win in the machine Mega Jack
IC DS5000T (commonly referred to as «DALLAS»). This is one of the most tamper-resistant commercially available processors. There are as available and not available for reading area. In the reach of just part of the program is stored, which is responsible for issuing the layout of characters on the screen in videobarabannyh (slot) games. This refers to the following: on a specific command (for simplicity - press START) issued a set, presented on the screen in the form of fifteen characters. In Dallas and stored INCASO EEPROM STATISTIC. In the DALLAS chip card information is transmitted on the IN, OUT, BET, WIN, and some other parameters, both current and absolute values.
Everything else (including mathematics for doublings, bonuses, poker games) is in the chips U1, U2, and they are not protected from reading.
There are two currently known how to win Mega Jack.
The first way hack - the substitution of the ROM U1, U2. Instead, staff set their own chips (with the program "patch" or a bug). How it works - on the set of a password from the keyboard the machine is won or some combination, or drops a bonus, or perhaps doubling does not make mistakes. In fact, at this moment we are not dealing with MegaJack, but with a completely different algorithm (so that the developers have laid the bug). Out of this regime is realized, for example, removing the credit, set another password, and so on - depending on the flights of imagination of the developer. Typically, for each chipset has its own password, so knowledge of a password does not guarantee knowledge of all. The two most common variants of the "work" for the substitution of chips with firmware bugs. The first is the ROM (chips) are mounted in the board, are in it for a while, then comes the "player" and won him the necessary amount. These "visits" may be repeated several times, and between the device behaves like a normal MegaJack. The second way: at some point made a substitution bagov chips, won the required amount of chips and regular return. In order to replace the ROM chip with a bug, you need to power off the machine. Insertion of a bug in the ROM content is performed by the programmer.
The second method hack is to install a bug in the gaming machine MegaJack - chip Dallas. This is the most dangerous for the owners of vehicles the way. The method of obtaining a prize is almost the same (set a password, etc.). There are dramatic differences in the way it is implementing the "Bookmarks". Most importantly, it is impossible to determine whether there was general alter DALLAS. At this moment I will focus in more detail. As already mentioned, DALLAS - One of the most tamper-resistant kriptoprotsessorov. It is understood that spelled out in a closed area of ??information can not be read by an ordinary programmer, even if it supports this type of chip. It turns out that you can not assume (as in the case of the ROM) and compare with the original content of this chip. In this case it is impossible to determine when it was done "tab" and by whom. Hence, the high cost of the program to insert a bug in dallas slot machine Mega Jack (version 30.25) and for its flash programmer.
It should be noted that in all versions of Mega Jack «younger" than 30.25, there are "holes" - such as the version 1.25 has a bug with shutting down. That is to win against such a gaming machine may not be getting into the compartment with no access fees. While something similar can be present in 30.25, such rumors are always there.
