Hi, I want to create a trainer for an emulated game (Super Mario 64). I have a specific opcode I need to NOP, but the only way it can be found is by manually searching for it each time by right-clicking on the address it writes to and clicking "Find what writes to this address", and then it finds the opcode and I can NOP it. This is because each time the game is reset or the emulator is closed and opened again, the opcode I'm looking for is located at a different address and I have no idea how to find a static address or pointer to it. So, is there any way to make a trainer that takes a known address and searches for what writes to it?

are you sure you can't find it by scanning for it's byte signature?

you can do a find what wrires in lua, but it's not as easy as an aobscan
check out http://cheat-engine.googlecode.com/svn/trunk/Cheat%20Engine/bin/main.lua
and look up debugger_onBreakpoint and debug_setBreakpoint.

use setBreakpoint to create a write triggered breakpoint, an in onBreakpoint fetch the address from EIP/RIP and go from there.
(note that the instruction pointer contains tge address of the instruction right after it)
