​ eight-door artifact is a common game modification tool on Android, iOS and Symbian platforms, which can modify values and parameters in memory. When the game is running, both the memory and the processor will exchange and change very complex data for the game. Because the game has a lot of data, such as money, HP value, rating, attack, defense, combat effectiveness and other data, especially the PVE combat on the client side. Lack of server verification and so on. And these data, in the various addresses of the memory and the processor, the player only needs to search for the relevant data values in the eight artifacts, and the eight artifacts will display each address that records this data. After many data changes, the player will search again, and finally will determine which address this address is, and then modify the value of this address. Back in the game, the relevant data will also change. The principle of the eight-door artifact is like Kingsoft Ranger, whole-person expert, game modification master and other types of modification software, but the eight-door artifact can only be used in smartphones.

​ is unable to modify or save the modified data when the eight artifacts are modified in the game, because the game itself has undergone special processing. Safe plastic surgery. Mainly used for memory storage function. Prevent plug-ins such as eight-door artifacts from tampering. According to the plug-in mechanism, the simple encryption of memory shaping can be used in game development. That is, the real value An is hidden. The value in memory is just the shadow of A. The specific principle is the ingenious application of OR and operation.

Or operation principle

1. Constant An or variable = constant B. Variable or constant A = constant B. Constant Alav 383391203 constant BRV 34603266 Analysis: the distribution is converted into binary and the formula 10110110110100001010111100011&0X01X00X10X0XXXX0X0X1000XXX10 is equal to: 000100001000000000100000010 conclusion: variables are regular, in which X can be 0 or 1, the number of 12 Xs can be: 1nValue) return true; return false;}}
