Ok, so I've been researching how to change an opcode via injection with C++, and i've ran into a huge problem. The address of the opcode that i'm trying to direct to a cave and store, lets say, the value of health, changes everytime you restart the game. Is there any way to scan the addresses for a certain opcode via c++ so I can inject my new opcode so I can finally defeat this DMA problem?

Someone said something like "look up SigSeek," but there doesn't seem to be any documentation on that.

Note: I have done days and days of pointerscans and sorting through ASM code, I have given up on it.
