You should do the Cheat Engine tutorial and learn about pointers. There's no need to be editing anything in the EXE.

Google for Ollydbg, download it, and the tutorials there will tell you how to save the changes to the EXE file.

which is why I am 99.999% of the time set to invisible.

Also, I predicted the outcome of this thread from the first post, which is why I didn't reply...

Anyhow, to try to answer the op's question:
that the address changes each time is because the game calls memory allocation routines and windows assigns a random location to the game each time.
So, you will have to edit the .exe where it initializes that specific region of memory. Perhaps you could set a hook on the memory allocation routines to find out what code allocates what, then find the address in a allocated block, find what initializes it, and with some luck you may find the initialization routine nearby.
Then edit that initialization routine so it sets a specific value on the address.

And I think I just thought of yet another reason to delay the next ce version because I might have to implement a new feature that sounds pretty useful

Lol, DarkByte sometimes I think you tell us exactly what to do in as simple a way as you can KNOWING its still going to confuse us just to be ironic.

Yes and you can use CE to locate the current address in the executable as well. Thats if you are in the exe and not a DLL.
Afer you know where it is you can edit it with CE or use OllyDBg or a hex editor as well. BUt using CE or Olly would be a better bet.

Then you could possibly run into some crc checks because you edited the file.

Simplest way to find it in the module your looking in is to use CE.
