This program is designed to find differences in the groups of binary files. Download any 2 or 3 groups of files (in columns A, B, or A, B, C). Each group ignored the bytes that differ within the group. Then compared between the groups of remaining bytes. The bytes that differ between groups – this is the desired results, their addresses are stored in a text file. The practical application of this – for revers. For example, you should look into the RAM storage device some options. Done by some (to screen foreign change) dump RAM in different states of the desired option. Then use RamDumpCmp eliminated foreign addresses and calculates the address associated with the change option.
