This compatibility fix fixes problems with any application that uses the Shrinker resource compression library. This library hacks resource functions in ntdll and kernel32 and redirect calls into their own function routines. But Ntdll code has different opcodes in Windows XP. The program failed to find the opcode signature and decided to cancel WriteProcessMemory call to write their redirection. Because of this, the necessary decompression of program code and resources were not executed and caused access violation. Shrinker compatibility fix resolves this by providing necessary opcode signature so the app could write those redirection into ntdll.
